list.files wildcard

Hello all,

I have a simple question:

I have filenames that look like these:
 "n031ku09.10msmeanc" "n031ku10.10msmeanc" "n031ku11.10msmeanc"
[22] "n031ku12.10msmeanc" "n031ti01.10msmeanc" "n031ti02.10msmeanc"

I also have a set of the same without the "c" at the end.

When I run list.files(".", pattern="*ku[01-30].meanc"), I get no result.
I'm guessing that what I have here a problem with "." as a wildcard or
metacharacter. How do I get it to read as a literal in that expression?

No, that's not the problem. If you do
  a<-c("n031ku09.10msmeanc", "n031ku10.10msmeanc", "n031ku11.10msmeanc")
  grep("*ku[01-30].meanc",a)
you still get no files, so the problem is with the regular expression.

[01-30] doesn't mean numbers between 01 and 30. It means a single
character that is 0, between 1 and 3, or zero

You can get nearly the right thing with
   "*ku[0-3][0-9].10msmeanc"
which matches numbers from 01 to 39
