Thanks. Unfortunately if I run R CMD INSTALL
I get this:

[...]
  preparing package zoo for lazy loading
Error in tools:::.read_description(file) :
        file '/DESCRIPTION' does not exist
Execution halted
make: *** [lazyload] Error 1
*** Installation of zoo failed ***

Removing 'C:/PROGRA~1/R/RW2001~1/library/zoo'

I get a similar message if I run R CMD build --binary .

The DESCRIPTION file definitely exists so I assume it to
be something else.  

If I run run R CMD check then it crashes (that is,
I get a popup asking me if I want to send a bug report to 
Microsoft) at various points depending on which example
code in the .Rd files I comment out).  If I comment out
enough to let it run past them all then I get the following
(where I have added the dots at the beginning of each
line in this post to circumvent's gmane's top posting filter):

I assume its the cleanEx line that is the problem but that is
not one my lines.  I would have tried it with an earlier
version of R but I don't want to overwrite the version
of the package I have installed on R 2.0.0 since then I will
be unable to proceed at all.

I am using Windows XP and R 2.0.1beta .
