Pattern match in R
Try this where ? signifies that the prior character is optional: dir(pattern = "^Coverage_[1-9]?[0-9]$") On Tue, Sep 30, 2008 at 10:36 AM, bioinformatics_guy

I want to make sure this piece of code I wrote is doing what I want it to do.
ll<-function(string)
{
grep(string,dir(),value=T)
}
subdir = ll("Coverage_[1-9][0-9]$")
I basically wrote a little function that would grab all the files of form
Coverage_[0-99]
The way I wrote it, will it grab Coverage_5 or does it have to have 2
numbers (10-99)?
