D <- read.csv("sample1.csv", header = FALSE, sep = ",")

D V1 V2 V3 V4 1 20100316 109825 352120 239065 2 20100317 108625 352020 239000 3 20100318 109125 352324 241065

D[,1] [1] 20100316 20100317 20100318

In the above example how do I get the data in D[,1] to be read, and stored as date values: 2010-03-16, 2010-03-17, 2010-03-18 ? I have lots of data files in this format.

TIA,

My data: It's a 71 MB file with 1.5 million rows. It has 6 fields All six fields combine to form a unique key - so that's what I need to sort on. Sort statement: sort -t ',' -k1,1 -k2,2 -k3,3 -k4,4 -k5,5 -k6,6 -o output.csv input.csv The problem: If I sort without keys, it takes 30 seconds… >>> More
