I'm a bit behind, so I'll do an update after I post this. 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. I tried those things: sudo -H gedit /etc/apt/sources.list then I added this line: deb focal/ then sudo apt-get update and sudo apt-get install r-base but it doesnt work.

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'. # Installr includes a package migration tool but this simply copies packages, it does not update themĬ was trying to update my libraries. This calls package names and installs them from repos, thus all packages should be correct to the most recent versionįor ( p in setdiff( packages, installed.packages())) # Install library - run in the new version of R. Install.R() # download and run the latest R installer If( !require( installr)) #load / install+load installrĬ() # tells you if there is a new version of R or not. # Run in the old version of R (or via RStudio)

Update r package
