Apparently it does not like that the fact that your user 'David
Stevens' has a blank.
Looking at the documentation ?install.packages
it seems that if you modify your call to something like
install.packages('callr',destdir='C:\tmp')
you might be ok. (caveat: I did not try this)
You should make the directory C:\tmp (or whatever you use instead)
before you issue this call.

Thanks Eric - I had tried this and failed with
install.packages('callr',destdir='c:/myRLib')

Certain, but not all? Which packages are you able to install on that
computer?
Too many to name - one is nlstools. Another is tinytex. I updated many package
after bookdown wouldn't install for the same reasons. Out of a list of ~20
packages to install, ~5 failed with a similar error message. That sent me down
the rabbit hole that brought me here.
Warning: invalid package 'C:\Users\David'
Warning: invalid package
'Stevens\AppData\Local\Temp\Rtmpk5NqrI/downloaded_packages/callr_3.4.0.tar.gz'
This looks like a command line argument quoting issue.
I wonder why doesn't install.packages use shQuote to quote the file
name when calling system2(c("R", "CMD", "INSTALL",
file)) to install a
downloaded source package:
https://github.com/wch/r-source/blob/e554f7f12b22868bdae51aadaeea4d56c9f87a32/src/library/utils/R/packages2.R#L833
Maybe there should be shQuote(fil) instead, especially since R does
quote the file name when installing from local source tarballs:
https://github.com/wch/r-source/blob/e554f7f12b22868bdae51aadaeea4d56c9f87a32/src/library/utils/R/packages2.R#L676
This happens on only a subset of packages I install or update.
I have a hypothesis: perhaps this only happens for packages with no
pre-built Windows binary available yet, since "win.binary" packages
may
be installed by unpacking a zip file, without calling a command line
with potential space quoting issues:
I read a thread elsewhere that said a work around is to run
options(pkgType='binary') before installation and the problem went away.
Does this help.
https://github.com/wch/r-source/blob/e554f7f12b22868bdae51aadaeea4d56c9f87a32/src/library/utils/R/packages2.R#L491

Calling install.packages(..., verbose = TRUE) for both a succeeding and
a failing package might help to verify whether this is the case.
This is a relatively recent issue (i.e. I never saw it before
November - I've used R for ~15 years).
Just to confirm it: you had no problems on the same Windows 10 computer
with the same user name and %USERPROFILE% path as before?
Yes, this is the case. I do the regular Windows 10 updates and update R and
RStudio as soon as I am aware there's a new version out. I haven't
explicitly change %USERPROFILE%.
Apparently,
tempdir() used to return a 8.3 directory path on your computer, but now
doesn't - but that should not happen, since R_reInitTempDir()
explicitly asks for a 8.3 path:
tempdir() gives
tempdir()

Microsoft Docs page for GetShortPathName() says:
If you call GetShortPathName on a path that doesn't have any short
names on-disk, the call will succeed, but will return the long-name
path instead. This outcome is also possible with NTFS volumes
because there's no guarantee that a short name will exist for a
given long name.
Some newer Windows 10 installations may have
NtfsDisable8dot3NameCreation enabled, thus preventing R from getting a
8.3 path to the temp directory.
I am taking the liberty of Cc-ing R-devel because this might warrant
adding a shQuote() call to install.packages().

This outcome is also possible with NTFS volumes because there's no guarantee that a short name will exist for a given long name. Some newer Windows 10 installations may have NtfsDisable8dot3NameCreation enabled, thus preventing R from getting a 8.3 path to the temp directory. I am taking the liberty of Cc-ing R-devel because this might warrant adding a shQuote() call to install.packages(). -- David K Stevens, PhD, PE Environmental Engineering Division Civil and Environmental Engineering Utah State University 8200 Old Main Hill Logan, UT 83200-8200 (435) 797-3229 david.stevens at usu.edu<mailto:david.stevens at usu.edu> [[alternative HTML version deleted]]
