Hi,
Thank you for your responses.
Héctor, I had also discovered the solution you suggested. However, when I
install files from a list (such as pckg.list), failure in the installation of
one package in the list results in none of the packages later in the list being
installed. After moving the 'problem' package up one level and deleting the
empty temporary directory, the name and name attribute of the problem package
must be removed from the list before loading the list and calling the function
install.packages() again. With multiple failures in the list of packages, that
can get tedious.
Duncan, I suspect you are correct that a file within the directory for the
'failed' package may have been locked by an antivirus program or some other
background process so that the package directory cannot be renamed. However,
although I am able to disable the virus check of files on my home desktop and
laptop (which I will do in the future), I have no control over such
applications as the enterprise-wide antivirus program in my office desktop. (I
have administrative rights only on my local machine.) Could the internal
function normalizePath() be rewritten so that before it attempts to convert the
path of a package directory to a subdirectory of the library directory it
checks whether it has access to the file and pauses until it has access or for
some reasonably short time? Please excuse me if I have just displayed
ignorance or arrogance. I suspect, however, that there are more than a few
users of R who have these problems and cannot control all the background
applications on their machine.
Again, thank you both.
Maurice

Hi,
This also happens in 2.9.1 and 2.9.2. My personal solution is to look
under ' C:\Program Files\R\R-2.9.0\library' for a bizarre-named
directory (starts with an 'f' and has numbers and letters mixed) ,
which contains the package directory (in this case 'robustbase') and
move it up one level (like the other packages). This is annoying, but
so far is the only solutions I have found.
I haven't been able to reproduce this, so all I can do is guess at the
cause, but it looks as though a directory rename failed. One cause for
that would be that some application (like a virus checker, or file
indexer, or some other background process) has a file open within the
directory. You could try disabling all such programs (though it's not
easy in Windows, there are lots of ways to start them) and see if that
helps.

On Sun April 19, you posted the following on R-help:
After installing 2.9.0 I tried loading packages, but keep getting
the following error.
package 'robustbase' successfully unpacked and MD5 sums checked
Error in normalizePath(path) :
path[1]=C:\Program Files\R\R-2.9.0\library/robustbase: The
system cannot find the file specified
I have had the same problem for months. Have you found a solution?
There have been two patch releases since 2.9.0. Have you tried 2.9.2?
