writing to the screen and extra "0"

I am using the "write" function like so (R 3.0.1 on linux):

"wrt" <-
function()
{
     write(system("ls *"),file="")
}

When the files are listed to the screen with wrt(), there is a "0"
character prepended to the output on the screen.  Worse, when I remove
the 'file=""' argument to "write", a file named "data" is created in my
default directory, with a zero in it.

All I am trying to do is output the "ls" of files in my directory,
without any extra characters or type-attribute information.  Thanks for
your help!

Hello,

Try instead


list.files(pattern = "*")


Hope this helps,

Hi.

list.files(pattern = "*")

gives me output with the R list indices at the left of each line on the screen.  I want only file names.

Thanks!
