I still forget it and stare into space for a half hour every time it happens. :slight_smile:

Thank you! You are all so kind and helpful - been staring into space for well over an hour! :wink:

About every other Mac OS update seems to break and not attempt to refigure things relative to C++ toolchains. Mojave was especially brutal. Not criticizing the Mac here (I love macs), just saying. xcode is almost always the fix.

[image] andresrcs: xcode-select --install I'm still getting the same error :frowning: The downloaded source packages are in ‘/private/var/folders/yq/1q1qc8g952vd68jyw6z1jxyr0000gn/T/RtmpmWRxnG/downloaded_packages’ Error in library(ggplot2) : there is no package called ‘ggplot2’ Has this …

[image] vbUCSF: Then the same error... When you say "the same error" which do you mean? If you could paste the output of the installation, as you did in the original post, it would be helpful. Also, I understand that this might not be possible if you're in a corporate environment, but have y…

[image] mara: 3.5.3. Thank you, Mara. I will try and update it now. I also keep getting the error: Warning in install.packages : package ‘ggplot’ is not available (for R version 3.3.2) I'm so confused - I just ran this code a few days ago and it was all fine :frowning:

I am still not able to run plyr or dplyr or ggplot (these are pretty much the only packages I know how to use!) see below... Do I need to do something about the last line... where it says where the packages are? R version 3.5.3 (2019-03-11) -- "Great Truth" Copyright (C) 2019 The R Foundation for S…

You are showing everything but the relevant error message, what is the whole output of running this command? install.packages("Rcpp")

Problems with loading ggplot2 General

You need dependencies = TRUE. Exit and re-open RStudio then run this install.packages("ggplot2", dependencies = TRUE, repos = "http://cran.us.r-project.org") I usually use pacman package to manage my packages. It will check if packages are already existed. If not, it will install and load the missing ones https://cran.r-project.org/web/packages/pacman/vignettes/Introduction_to_pacman.html Cheers
