Hi Pete Pete,
Try
# option 1 -- 100 files
sapply(1:100, function(i){
x <-sample(rnorm(1000, 100, 15), 12, replace = FALSE)
write.table(x, paste("sample", i, ".txt", sep =
""), row.names = FALSE,
quote = FALSE))
})
# option 2 -- all the information in one file
d <- replicate(100, sample(rnorm(1000, 100, 15), 12, replace = FALSE))
write.table(d, "allsamples.txt", sep = "\t", row.names =
FALSE, quote FALSE))
HTH,
Jorge
