I have 30 files in the current directories, i would like to perform the
cbind(fil1,file2,file3,file4file30)
how could i do this in a for loop:
such as:
file2 - list.files(pattern=.out3$)
for (j in file2) {
cbind(j)...how to implement cbind here
}
Thanks.
Hi,
Assuming that you have read the files into R,
and that their names (in R) are held in some object
(e.g., 'file2'), then this works
do.call(what = cbind, args = mget(x = file2, envir = .GlobalEnv)
Here is a reproducible example:
x1 - data.frame(x = 1:10)
x2 - data.frame(y = 1:10)
file.names

Try this:
do.call(cbind, lapply(dir(pattern = '.out3$'), read.table))
