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)
