R help - May 2010 - Filters()

Hello,

I was wondering whether there is a possobility to add File types to the list
of filters known by R.

I'm using the function choose.files in Windows. I have some files I always
use and i would like to filter my option to these kind of files.
I have some "atr", "cdt", "gct", "gmt"
etc.

Is there a way of telling R to filter only these files?

Thanks

Assa

Yes, see ?choose.files.  Just specify filters=yourFilters.  If you want 
to make a permanent change, you write your own choose.files function to 
mask the one in the utils package, or you could use (but expect others 
users of choose.files() to break when you do this).

assignInNamespace("Filters", yourFilters, "utils")
