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 know. 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 them. 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. pj -- Paul E.
