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):

.> # runmean(x, 5)
.> # runmax(x, 5)
.> # runmed(x, 5)
.> cleanEx(); ..nameEx <- "value"

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.
