Hello!

I have just encountered the same situation as Heather and also Paul Gilbert at

http://tolstoy.newcastle.edu.au/R/devel/05/02/2095.html

I went into install.packages() in current release as well as in R-devel and there is really no problem with \ or /. However, I also had the same warning

> install.packages("RODBC")

[... snip ...]
Delete downloaded files (y/N)? y

updating HTML package descriptions
Warning message:
unable to move temp installation 'N:/Ovce/Programi/R/rw2001/library\file27583/RODBC' to 'N:/Ovce/Programi/R/rw2001/library/RODBC'

The warning is issued from this part of install.packages()

if (ret == 0) {

                ## Move the new package to the install lib and
                ## remove our temp dir
                ret <- file.rename(file.path(tmpDir, curPkg), instPath)
                if(!ret) warning("unable to move temp installation ",
                                 sQuote(file.path(tmpDir, curPkg)),
                                 " to ",
                                 sQuote(instPath), call. = FALSE)
            } else {
                ## !! Can't revert to old 'zip.unpack' as it would
                ## !! potentially leave cruft from a bundle in there
                stop("Can not remove prior installation of package ",
                     sQuote(curPkg), call. = FALSE)
            }

"Problem" lies in

ret <- file.rename(file.path(tmpDir, curPkg), instPath)

I went through the whole function "by hand" and at first the above line didn't moved tmpDir to instPath. I tried several times and after a while it was successfull. It is strange that it happens only with some packages i.e. in my case with RODBC and car. I also noted that line above takes quite a lot of time to "accomplish" its work. It actually causes R to freeze for a moment. If I launched

file.rename(file.path(tmpDir, curPkg), instPath)

move was done in a moment. I know, that this comment is not the answer to the problem. However, someone might come with that.

One more thing. I have R installed on networked disk. I assume that Heather does also, since disk letter is H. On the other hand, Paul reported problems with C disk.

Since you _incorrectly_ assume that the syntax is incorrect, the rest of your assumption is incorrect. As the FAQ asks, please don't speculate about things you are not expert about, but stick to facts. Also as the FAQ asks, don't misuse R-bugs for things you do not know _for sure_ are bugs in R.

FYI, Windows accepts both /and \ in file paths, including a mixture. If your speculation was correct install.packages() would work for no one, and do you seriously think that such a bug would go unreported and unfixed.

We have seen this once before, and it was a Windows bug solved by updating Windows to the latest set of patches. Since you have not reported a precise version of Windows, it is hard for us to know what you were using, but if you mean NT4.0, that is rather old (last Service Pack five years ago I read yesterday).
