• R equivalent of SELECT DISTINCT on two or more fields/variables

  - by wahalulu

  Say I have a dataframe df with two or more columns, is there an easy way to use unique() or other R function to create a subset of unique combinations of two or more columns? I know I can use sqldf() and write an easy "SELECT DISTINCT var1, var2, ... varN" query, but I am looking for an R way of doing this. It occurred to me to try ftable coerced to a dataframe and use the field names, but I also get the cross tabulations of combinations that don't exist in the dataset: uniques <- as.data.frame(ftable(df$var1, df$var2))

• Change the key being pressed with C#

  - by Benny

  Hey, I'm trying to write a program in C# that will track the pressing of certain keys (using a keyboard hook), and send different ones instead. For instance, when I press the A key it will instead send the Q key.

• Stored Procedure in postgresql, multiple queries w/ agreggates.

  - by fenix

  I'm trying to write a store procedure that can take some input parameters (obviously), run multiple queries against those, taking the output from those and doing calculations, and from those calculations and the original queries, outputting a formatted text string like: Number of Rows for max(Z) matching condition x and y of total rows matching x (x&y/x*100). To explain the max(Z) bit, this will be the username field, it won't matter which actual entry is picked, because the where clause will filter the results by user id, is there a saner way to do this?
