Is there something that's changed with the way proxy servers are used? was the question that led me to check out the changes in R 3.4.0 which mentions visible changes to download.file(). So I tried method = "internal" which worked! So making the same setting to the call to install.packages() fixed my problem. Thanks for all the suggestions which led me to the solution. I just wonder if there could be a more informative error message. -- ~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~. ___ Patrick Connolly {~._.~} Great minds discuss ideas _( Y )_ Average minds discuss events (:_~*~_:) Small minds discuss people (_)-(_) .....
