I'm a bit behind, so I'll do an update after I post this.Today I finally got around to updating my R to 3.5 (or, more specifically, 3.5.1). I'm not sure if this is an R or R Studio problem
After I click on it, the install fails, then it says I need to restart R. Namespace ‘rlang’ 0.3.0.1 is already loaded, but >= 0.3.1 is requiredĮrror: package ‘ggplot2’ could not be loadedĪ third problem that occurs, is when I tried to install 'rlang' (without first uninstalling it), I get a message that R needs to be restarted with a restart button. I should mention the whole thing started with loading another library, which in turn, try to load ggplot2: > library(Hmisc) # for minor.tick() used in plotting Įrror: package or namespace load failed for ‘ggplot2’ in loadNamespace(i, c(lib.loc. It did occur to me to uninstall and reinstall, which I did. I tried installing it: > install.packages("rlang")Įrror in install.packages : Updating loaded packagesĪ) when I did this with a list, the error message failed to tell me which package(s) out of the list failed.ī) The error message is too vague, I wasn't sure what was wrong or how to fix it.
At some point, I got an error with 'rlang'.
