R help - Sep 2009 - Change directory to implement same programes

HI, R-Users,

I have one problem:

I have written the the programs which process all file in one directory: for
example:

setwd("C:/Documents and Settings/lma/My Documents/Vappu-saved/Log") as
the start.
..........

But I have many folders like "Vappu-saved" and there are a lot of
files in each directory. What I want is using the same program what I write for
the above directory
 to autimatically change directory address to implement the above programs what
I wrote. How do I realize it?

Thanks a lot.

Regards,
Lingyi

Hi,

You can use list.files() of Sys.glob to get a listing of all the files 
in a certain directory, e.g. to get all ".R" files and source them:

for(f in Sys.glob("C:/Documents and Settings/lma/*.R")) source(f)

cheers,
Paul
