[R] A vector or array of data frames

[Dimitris Rizopoulos]

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.

Best,
Dimitris
