![]() ![]() Update.packages(ask = FALSE, checkBuilt = TRUE) In order to update your already installed, just type the following in the R console: We still have work to do though… Updating R 3.x packages to the new R 4.0.Īs R 4.0 introduced several changes to base functions, programmers had to rewrite their packages. $ sudo add-apt-repository 'deb focal-cran40/' If you don’t have this line, you can run the following in a terminal session to use the R CRAN version: In the terminal emulator, type and run sudo apt install software-properties-common.įirst, you need to check the file ‘/etc/apt/sources.list’, and look for the line. ![]() You may need to install the package software-properties-common. If you’re using a Linux distro, the process is a breeze. How can I update my R 3.x to the new shiny R4.x? Reinstall your 3.x packages to the new 4.0.Keep your R version always updated using the CRAN version.Updating R was a bit of a headache that I wouldn’t like others going through. Finally, it’s time to say goodbye to ‘stringsAsFactors=FALSE’. Today I was forced to update to R 4.0 due to a new research project I was invited to collaborate. Maybe I’m just getting older and, as the time flies, more resistant to dealing with changes. I must confess: I’d rather use stable and long-term release software. I have updated this guide to use the full key out of security concerns (see here, for example).How to update R 3.x to the new R 4.x in Linux Ubuntu (replacing with whichever CRAN mirror URL you chose in step 1)ġ I put here the full key, though many other guides you may see will use only the "short key." You need to use sudo echo "deb bionic-cran35/" | sudo tee -a /etc/apt/sources.list The only difference is that instead of the command sudo echo "deb xenial/" | sudo tee -a /etc/apt/sources.list Since both Linux Mint and R have seen upgrades since I answered this question, I'm updating for those who come to this answer needing the info for Linux Mint 19 and R 3.6.x. Start a new R session and run the following: update.packages(checkBuilt=TRUE, ask=FALSE) If not, I highly recommend you install it via sudo apt install r-base-dev. Note also that I have put to upgrade r-base and r-base-dev, but I don't know if you have r-base-dev installed. Sudo echo "deb xenial/" | sudo tee -a /etc/apt/sources.list Open a terminal and enter the following commands 1 (replacing with whichever CRAN mirror URL you chose in step 1): sudo apt-key adv -keyserver -recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9 The terminal commands below assume you choose Step 2 Go to CRAN's list of mirrors and find the URL of the mirror that is closest to you. ![]() So, for completeness, these are all the steps you'd need to take: Step 1 I also typically use the approach here to deal with packages I've already installed when I upgrade R rather than the approach offered by FedRo. The link provided by FedRo is a good resource, however a slight change would need to be made since you're using Linux Mint 18.1 which uses Xenial repositories rather than Trusty repositories (see here). Note: I now keep on GitHub ( here) an up-to-date guide to upgrading R on Linux Mint or Ubuntu Linux, which also includes a bit of extra information about system dependencies for tidyverse, the popular set of data-wrangling packages, as well as devtools, the popular R package development. ![]()
