I have problems to install some of the packages dowloaded from CRAN
(whatever the procedure: install from CRAN or from local zip file). I
noticed this today, while running update.packages().

> install.packages("G:/Zip/R/1.5.0/Contrib/chron.zip", .libPaths()[1], CRAN = NULL)
Error in zip.unpack(pkg, lib) : cannot open file

I meet the same problem with lattice (and others), but it works
sometimes e.g.:
> install.packages("G:/Zip/R/1.5.0/Contrib/mgcv.zip", .libPaths()[1], CRAN = NULL)
updating HTML package descriptions

If I manually delete the library before installing it, it works again:
> install.packages("G:/Zip/R/1.5.0/Contrib/chron.zip", .libPaths()[1], CRAN = NULL)
updating HTML package descriptions

The problem does not seem to be related to R versions incompatibility
(Rwin FAQ 3.5). For example, with package chron, the content of the
Package: chron
Version: 2.2-21
Author: S original by David James <dj at research.bell-labs.com>,
  R port by Kurt Hornik <Kurt.Hornik at ci.tuwien.ac.at>.

Is this a problem witb my OS or something else ?
