[R] process all files ending in *.dat

[Paul E Johnson]

On Linux (RH7.1) with R installed from CRAN rpms:

I have many files with miscellaneous names *.dat. I would like to
successively open each one, run some functions on them, and then write
some output numbers to *.summary.  I have succeeded in doing this when I
type in each file name individually for the data input, but have not
found a way to search files in a directory and grab the *.dat.  If
somebody could tell me syntax or example of how to find the files, and
get the basename in order to create the new file name, I would be
grateful.
 
I tried
mydat<-system("ls *.dat")
but mydat does not catch the return.
Thanks for your many helps in the past...
