Hi,
When installing packages in Windows (currently using Windows 10 with all service packs), occasionally, I get a warning similar to the following: package 'Rcpp' successfully unpacked and MD5 sums checked Warning in install.packages : unable to move temporary installation 'C:\Users\William Denney\Documents\R\win-library\3.4\file32701900456\Rcpp' to 'C:\Users\William Denney\Documents\R\win-library\3.4\Rcpp' This can occur when installing many packages where the package that could not be moved (e.g. Rcpp) is a dependency. In the end, the package where the warning is issued is not available to load, and I have to spend time figuring out why. The usual reason is that for some reason during the package install process the library directory ("C:\Users\William Denney\Documents\R\win-library\3.4\") has been set to partially or fully read-only. I have a couple of questions: * Why is the directory set to read-only? It happens almost every time that I install packages that are compiled. (It doesn't seem to occur with interpreted-only packages.) * Shouldn't that warning be an error or at least prevent the packages that depend on the one that couldn't be moved from being installed? The way that it tends to go, package installation completes with that warning, and then I have to clean up the mess of missing dependencies.
