I'm including the relevant (I think) information. I get the students to install rms with dependencies. As you can see, rms does get installed but when the attempt is made to attach it, ggplot2 cannot be loaded. Thus I tried explicitly installing ggplot2 and you can see then ensuing errors below. I have included the sessionInfo() at the end.

I have just seen this on Win10 for the first time on a student's new
laptop. Anti-virus software is possible reason for this, but I don't
I did find a very direct solution.
WHen you run the package install, and it says "cannot move from
temporary C:\Users\yourname\AppData\XYZ to user directory
C:\Users\yourname\Documents\R\site-library", just move the folder
manually. It works every time.
Unfortunately, Windows hides AppData. In the Windows explorer view
options, tell it not to hide protected files. Then in explorer
navigate into the user's AppData\Temp\Rxxx folder, you'll see the
downloaded zip files there for Rcpp and such. Doubleclick the zip
file, right click copy the directory name "Rcpp" and paste it into the
user's R folder, under C:/Users/yourname/Documents/R/3.3/site-library
(or whatever that's called).
We ran into about 2 packages that have this failure to copy from
temporary space, but this old-fashioned copy a folder over method
worked fine. After this, R was able to load Rcpp, RcppEigen.
There is no indication that those R files are in a virus quarantine,
so I can't say for sure the security software is the cause. At first,
I thought the problem was the usual one that we have been aware of for
some time--Windows thinks those files are in use and will not replace
We are trying to remove a layer of virus protection programs
installed by Dell to see if this happens later. If I hear back from
that student, I'll let you know. Another layer in this story is that
her 30 day free trials were expired, and I have feeling this means
that not only is McAfee still installed, but it is also running but
refusing to let you interact with it.
