R2.1.0: Bug in list.files

Is that the entire story ? I tried this with yesterday's patched version 
(windows xp) and found:

 > list.files(getwd(),"*.txt",full=T)

Error in list.files(path, pattern, all.files, full.names, recursive) :
        invalid 'pattern' regular expression

 > list.files(getwd(),'.txt',full=T)

[1] "C:/Documents and Settings/suresh/BDE_SysInfo.txt"
[2] "C:/Documents and Settings/suresh/dxva_sig.txt"

Replacing "*.txt" with '*.txt' seems to do "something".

-s.

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)
