[R] Repeated failures to install "caret" package (of Max Kuhn)

[Max Kuhn]

I thought that this might be relevant:

https://stackoverflow.com/questions/28985759/cant-install-the-caret-package-in-r-in-my-linux-machine

but it seems that you installed nloptr.

I would also suggest doing the install in base R and trying a different
mirror. I would avoid installing via RStudio unless you have just started a
new R session.
