Re: [R] writing to the screen and extra "0"
Hi Thomas,
If you put the list.files statement inside the write function you won't
have the indices.
Try:
write(list.files(pattern="*"), file="my_files.txt")
Cheers,
Charles

Re: [R] writing to the screen and extra "0"
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!

[R] 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!
