(read many files)

Dear ladies and gentlmen, I want to import a directory with about 400
files (.dat) in R. I know how to import a single file (with scan...)
but I've good no idea how to import 400 at once. Can you help me ? 
Thanks a lot! Claudia 

setwd("c:/myfiles/")
## list.files uses regular expressions.
## For reading all files which start with "S" use for example:

files <-  list.files(pattern="^S.*")

## then read the data within a loop, e.g.:
dat2 <- NULL
for (f in files) {
   dat  <- read.table(f)
   dat2 <- rbind(dat2, dat)
}
