R help - Jun 2007 - scan a directory and then make a string vector consisting of file names

Dear R-users,

I am looking for a way to scan a directory and then make a string vector 
consisting of the file names in the directory.

For example, under c:\temp\
there are 4 files
a.txt, b.txt, c.txt, and d.txt

I would like to have a string vector
c("a.txt","b.txt","c.txt","d.txt")

How do I do that?

Thanks

Taka,

See ?list.files

For example:

  list.files("c:/temp", pattern = "\\.txt")

Note the use of the forward slash in the 'path' argument. See R Windows
FAQ:

I am looking for a way to scan a directory and then make a string vector

consisting of the file names in the directory.

For example, under c:\temp\
there are 4 files

I would like to have a string vector
c("a.txt","b.txt","c.txt","d.txt")
