• LAbeling with Percentage in R plot

  - by Libo Cannici

  Hi I have made this function that takes a table and prepare the label for a barplot prepare_labels <- function(ft){ labs <- ft labs <- paste(labs, "\n", sep="") labs <- paste(labs, round(prop.table(ft)*100,2), sep="") labs <- paste(labs, "%", sep="") return(labs) } It actually works fine, but is there any better way to write that function, the above code looks ugly and I want to write beautiful code :-) ex: ft <- table(mydata$phone_partner_products) prepare_labels(ft) [1] "3752\n34.09%" "226\n2.05%" "2907\n26.41%" "1404\n12.76%" "1653\n15.02%" [6] "1065\n9.68%"

• R table column order when including the empty string

  - by Libo Cannici

  I have a series of value that include the empty string levels(mydata$phone_partner_products) "" "dont_know" "maybe_interesting" "not_interesting" "very_interesting" "very_not_interesting" If I make a frequencies table I get this table(mydata$phone_partner_products) dont_know maybe_interesting 3752 226 2907 not_interesting very_interesting very_not_interesting 1404 1653 1065 How can I reorder the columns in a more meaningful way? How can I rename the empty string "" level? Thank you a lot in advance.

• Ethernet on an Acer Aspire One D255E not working

  - by Dustin

  Ok very frustrated here, but hopefully can find an answer here. I have an Acer Aspire One netbook D255E. I installed 10.04 desktop edition via live USB, only to find out ethernet is not connecting. The thing is, I had installed previously 10.04 thru wubi as 30GB, but wanted more so did this install. With the Wubi install it worked great internet worked added LibO, mint menu ect. So I know it could work, and it works on Win 7(what little GB is left). I have ethernet enabled, and gave myself all permissions, but still not working. Thank you for any help, and if you do more details in the steps i need to take the better :).

• codes to convert from avi to asf

  - by George2

  Hello everyone, No matter what library/SDK to use, I want to convert from avi to asf very quickly (I could even sacrifice some quality of video and audio). I am working on Windows platform (Vista and 2008 Server), better .Net SDK/code, C++ code is also fine. :-) I learned from the below link, that there could be a very quick way to convert from avi to asf to support streaming better, as mentioned "could convert the video from AVI to ASF format using a simple copy (i.e. the content is the same, but container changes).". My question is after some hours of study and trial various SDK/tools, as a newbie, I do not know how to begin with so I am asking for reference sample code to do this task. :-) (as this is a different issue, we decide to start a new topic. :-) ) http://stackoverflow.com/questions/743220/streaming-avi-file-issue thanks in advance, George EDIT 1: I have tried to get the binary of ffmpeg from, http://ffmpeg.arrozcru.org/autobuilds/ffmpeg-latest-mingw32-static.tar.bz2 then run the following command, C:\software\ffmpeg-latest-mingw32-static\bin>ffmpeg.exe -i test.avi -acodec copy -vcodec copy test.asf FFmpeg version SVN-r18506, Copyright (c) 2000-2009 Fabrice Bellard, et al. configuration: --enable-memalign-hack --prefix=/mingw --cross-prefix=i686-ming w32- --cc=ccache-i686-mingw32-gcc --target-os=mingw32 --arch=i686 --cpu=i686 --e nable-avisynth --enable-gpl --enable-zlib --enable-bzlib --enable-libgsm --enabl e-libfaac --enable-pthreads --enable-libvorbis --enable-libmp3lame --enable-libo penjpeg --enable-libtheora --enable-libspeex --enable-libxvid --enable-libfaad - -enable-libschroedinger --enable-libx264 libavutil 50. 3. 0 / 50. 3. 0 libavcodec 52.25. 0 / 52.25. 0 libavformat 52.32. 0 / 52.32. 0 libavdevice 52. 2. 0 / 52. 2. 0 libswscale 0. 7. 1 / 0. 7. 1 built on Apr 14 2009 04:04:47, gcc: 4.2.4 Input #0, avi, from 'test.avi': Duration: 00:00:44.86, start: 0.000000, bitrate: 5291 kb/s Stream #0.0: Video: msvideo1, rgb555le, 1280x1024, 5 tbr, 5 tbn, 5 tbc Stream #0.1: Audio: pcm_s16le, 22050 Hz, mono, s16, 352 kb/s Output #0, asf, to 'test.asf': Stream #0.0: Video: CRAM / 0x4D415243, rgb555le, 1280x1024, q=2-31, 1k tbn, 5 tbc Stream #0.1: Audio: pcm_s16le, 22050 Hz, mono, s16, 352 kb/s Stream mapping: Stream #0.0 -> #0.0 Stream #0.1 -> #0.1 Press [q] to stop encoding frame= 224 fps=222 q=-1.0 Lsize= 29426kB time=44.80 bitrate=5380.7kbits/s video:26910kB audio:1932kB global headers:0kB muxing overhead 2.023317% C:\software\ffmpeg-latest-mingw32-static\bin> http://www.microsoft.com/windows/windowsmedia/player/webhelp/default.aspx?&mpver=11.0.6001.7000&id=C00D11B1&contextid=230&originalid=C00D36E6 then have the following error when using Windows Media Player to play it, does anyone have any ideas? http://www.microsoft.com/windows/windowsmedia/player/webhelp/default.aspx?&mpver=11.0.6001.7000&id=C00D11B1&contextid=230&originalid=C00D36E6

• Compiling OpenCV in Android NDK

  - by evident

  PLEASE SEE THE ADDITIONS AT THE BOTTOM! The first problem is solved in Linux, not under Windows and Cygwin yet, but there is a new problem. Please see below! I am currently trying to compile OpenCV for Android NDK so that I can use it in my apps. For this I tried to follow this guide: http://www.stanford.edu/~zxwang/android_opencv.html But when compiling the downloaded stuff with ndk-build I get this error: $ /cygdrive/u/flori/workspace/android-ndk-r5b/ndk-build Compile++ thumb : opencv <= cvjni.cpp Compile++ thumb : cxcore <= cxalloc.cpp Compile++ thumb : cxcore <= cxarithm.cpp Compile++ thumb : cxcore <= cxarray.cpp Compile++ thumb : cxcore <= cxcmp.cpp Compile++ thumb : cxcore <= cxconvert.cpp Compile++ thumb : cxcore <= cxcopy.cpp Compile++ thumb : cxcore <= cxdatastructs.cpp Compile++ thumb : cxcore <= cxdrawing.cpp Compile++ thumb : cxcore <= cxdxt.cpp Compile++ thumb : cxcore <= cxerror.cpp Compile++ thumb : cxcore <= cximage.cpp Compile++ thumb : cxcore <= cxjacobieigens.cpp Compile++ thumb : cxcore <= cxlogic.cpp Compile++ thumb : cxcore <= cxlut.cpp Compile++ thumb : cxcore <= cxmathfuncs.cpp Compile++ thumb : cxcore <= cxmatmul.cpp Compile++ thumb : cxcore <= cxmatrix.cpp Compile++ thumb : cxcore <= cxmean.cpp Compile++ thumb : cxcore <= cxmeansdv.cpp Compile++ thumb : cxcore <= cxminmaxloc.cpp Compile++ thumb : cxcore <= cxnorm.cpp Compile++ thumb : cxcore <= cxouttext.cpp Compile++ thumb : cxcore <= cxpersistence.cpp Compile++ thumb : cxcore <= cxprecomp.cpp Compile++ thumb : cxcore <= cxrand.cpp Compile++ thumb : cxcore <= cxsumpixels.cpp Compile++ thumb : cxcore <= cxsvd.cpp Compile++ thumb : cxcore <= cxswitcher.cpp Compile++ thumb : cxcore <= cxtables.cpp Compile++ thumb : cxcore <= cxutils.cpp StaticLibrary : libstdc++.a StaticLibrary : libcxcore.a Compile++ thumb : cv <= cvaccum.cpp Compile++ thumb : cv <= cvadapthresh.cpp Compile++ thumb : cv <= cvapprox.cpp Compile++ thumb : cv <= cvcalccontrasthistogram.cpp Compile++ thumb : cv <= cvcalcimagehomography.cpp Compile++ thumb : cv <= cvcalibinit.cpp Compile++ thumb : cv <= cvcalibration.cpp Compile++ thumb : cv <= cvcamshift.cpp Compile++ thumb : cv <= cvcanny.cpp Compile++ thumb : cv <= cvcolor.cpp Compile++ thumb : cv <= cvcondens.cpp Compile++ thumb : cv <= cvcontours.cpp Compile++ thumb : cv <= cvcontourtree.cpp Compile++ thumb : cv <= cvconvhull.cpp Compile++ thumb : cv <= cvcorner.cpp Compile++ thumb : cv <= cvcornersubpix.cpp Compile++ thumb : cv <= cvderiv.cpp Compile++ thumb : cv <= cvdistransform.cpp Compile++ thumb : cv <= cvdominants.cpp Compile++ thumb : cv <= cvemd.cpp Compile++ thumb : cv <= cvfeatureselect.cpp Compile++ thumb : cv <= cvfilter.cpp Compile++ thumb : cv <= cvfloodfill.cpp Compile++ thumb : cv <= cvfundam.cpp Compile++ thumb : cv <= cvgeometry.cpp Compile++ thumb : cv <= cvhaar.cpp Compile++ thumb : cv <= cvhistogram.cpp Compile++ thumb : cv <= cvhough.cpp Compile++ thumb : cv <= cvimgwarp.cpp Compile++ thumb : cv <= cvinpaint.cpp Compile++ thumb : cv <= cvkalman.cpp Compile++ thumb : cv <= cvlinefit.cpp Compile++ thumb : cv <= cvlkpyramid.cpp Compile++ thumb : cv <= cvmatchcontours.cpp Compile++ thumb : cv <= cvmoments.cpp Compile++ thumb : cv <= cvmorph.cpp Compile++ thumb : cv <= cvmotempl.cpp Compile++ thumb : cv <= cvoptflowbm.cpp Compile++ thumb : cv <= cvoptflowhs.cpp Compile++ thumb : cv <= cvoptflowlk.cpp Compile++ thumb : cv <= cvpgh.cpp Compile++ thumb : cv <= cvposit.cpp Compile++ thumb : cv <= cvprecomp.cpp Compile++ thumb : cv <= cvpyramids.cpp Compile++ thumb : cv <= cvpyrsegmentation.cpp Compile++ thumb : cv <= cvrotcalipers.cpp Compile++ thumb : cv <= cvsamplers.cpp Compile++ thumb : cv <= cvsegmentation.cpp Compile++ thumb : cv <= cvshapedescr.cpp Compile++ thumb : cv <= cvsmooth.cpp Compile++ thumb : cv <= cvsnakes.cpp Compile++ thumb : cv <= cvstereobm.cpp Compile++ thumb : cv <= cvstereogc.cpp Compile++ thumb : cv <= cvsubdivision2d.cpp Compile++ thumb : cv <= cvsumpixels.cpp Compile++ thumb : cv <= cvsurf.cpp Compile++ thumb : cv <= cvswitcher.cpp Compile++ thumb : cv <= cvtables.cpp Compile++ thumb : cv <= cvtemplmatch.cpp Compile++ thumb : cv <= cvthresh.cpp Compile++ thumb : cv <= cvundistort.cpp Compile++ thumb : cv <= cvutils.cpp StaticLibrary : libcv.a SharedLibrary : libopencv.so U:/flori/workspace/android-ndk-r5b/toolchains/arm-linux-androideabi-4.4.3/prebui lt/windows/bin/../lib/gcc/arm-linux-androideabi/4.4.3/../../../../arm-linux-andr oideabi/bin/ld.exe: cannot find -lcxcore collect2: ld returned 1 exit status make: *** [/cygdrive/u/flori/workspace/android/testOpenCV/obj/local/armeabi/libo pencv.so] Error 1 I am trying to compile it on a Windows system and with the newest NDK version... Does anybody have an idea what this linking error means and what I can to to have it work again? Would be great if anybody could help After getting the problem to work I found that there is another way of compiling OpenCV for Android, using the current version of OpenCV (instead of the 1.1 one from above) and the modified Android NDK from crystax, which supports STL and exceptions and therefore supports the newest OpenCV Version. All information on that can be found here: http://opencv.willowgarage.com/wiki/Android There it says to download the current svn trunk and the crystax-r4 android-ndk, as well as swig, which I did. I entered the folder, created the build directory, ran cmake and then built the static libs, which seemed to work. At least it successfully ran the make-command without errors. I now wanted to build the shared libraries so I entered the android-jni folder and ran 'make' again, but got this error: % make -j4 OPENCV_CONFIG = ../build/android-opencv.mk make clean-swig &&\ mkdir -p jni/gen &&\ mkdir -p src/com/opencv/jni &&\ swig -java -c++ -package "com.opencv.jni" \ -outdir src/com/opencv/jni \ -o jni/gen/android_cv_wrap.cpp jni/android-cv.i OPENCV_CONFIG = ../build/android-opencv.mk make[1]: Entering directory `/home/florian/android-opencv-willowgarage/android/android-jni' make[1]: warning: jobserver unavailable: using -j1.
