R2.1.0: Bug in list.files

Note that sfsmisc::glob2rx is a handy function that will convert glob style
wildcard expressions to regular expressions.
Yes I missed the NEWS entry - or rather didn't realise its significance.
So the "bug" was in the previous version and my old code which worked
but shouldn't have.

Thanks for the replies - rapid and to the point as usual.

Steve.

Bug? or have I missed something
You missed to read the NEWS that tells you:

     o   The regular expression code is now based on that in glibc
     2.3.3. It has stricter conformance to POSIX, so metachars such as
     { } + * may need to be escaped where before they did not (but
     could have been).

Probably you want

  list.files(pattern = "\\.zip$", full.names = TRUE)
