R2.1.0: Bug in list.files

R2.0.1 (MS Windows)

list.files(myloc,"*.zip",full=T)
[1] "P:/SARsoftware/Rlibraries/gnlm_0.1.zip"
[2] "P:/SARsoftware/Rlibraries/lms2_0.2.zip"

R2.1.0:

list.files(myloc,"*.zip",full=T)
Error in list.files(path, pattern, all.files, full.names, recursive) : 
        invalid 'pattern' regular expression
>
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)
