you could use something like:
file. <- c:/data/dat # the path for the data
lis.dat <- lapply(1:B, function(i) read.table(paste(file., i, sep="")) )
where B is the number of files whose names are: dat1, dat2, ..., datB. Then lis.dat[[1]] will be the first data.frame.
I hope it helps.

Subject: [R] A vector or array of data frames
Hi
A simple question again, but I can't find it by google-ing R-help.
Quite simply, I want to read in the contents of a number of files, using
read.table, and assign the results to elements of a
vector/array/list/whatever.
I want it so that, if my vector/array/whatever is "pos", that pos[1]
will give me the first data frame, pos[2] will give me the second etc...
Kind of basic stuff I know... Sorry..
Mick
