How to Upgrade R in Ubuntu

How to upgrade R in ubuntu?

Since R is already installed, you should be able to upgrade it with this method. First of all, you may want to have the packages you installed in the previous version in the new one,so it is convenient to check this post. Then, follow the instructions from here

1. Open the sources.list file:

    sudo nano /etc/apt/sources.list    
   

2. Add a line with the source from where the packages will be retrieved. For example:

    deb https://cloud.r-project.org/bin/linux/ubuntu/ version/
   

   Replace https://cloud.r-project.org with whatever mirror you would like to use, and replace
   version/ with whatever version of Ubuntu you are using (eg, trusty/, xenial/, and so on). If you're getting a "Malformed line error", check to see if you have a space between /ubuntu/ and version/.

3. Fetch the secure APT key:

    gpg --keyserver keyserver.ubuntu.com --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9
   

or

    gpg --hkp://keyserver keyserver.ubuntu.com:80 --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9

4. Add it to keyring:

    gpg -a --export E084DAB9 | sudo apt-key add -
   

5. Update your sources and upgrade your installation:

    sudo apt-get update && sudo apt-get upgrade
   

6. Install the new version

    sudo apt-get install r-base-dev
   

7. Recover your old packages following the solution that best suits to you (see this). For instance, to recover all the packages (not only those from CRAN) the idea is:

-- copy the packages from R-oldversion/library to R-newversion/library, (do not overwrite a package if it already exists in the new version!).

-- Run the R command update.packages(checkBuilt=TRUE, ask=FALSE).

How to upgrade R in linux?

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... package.

---

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). 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. So, for completeness, these are all the steps you'd need to take:

Step 1

Go to CRAN's list of mirrors and find the URL of the mirror that is closest to you. The terminal commands below assume you choose http://cran.wustl.edu/

Step 2

Open a terminal and enter the following commands¹ (replacing http://cran.wustl.edu/ with whichever CRAN mirror URL you chose in step 1):

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
sudo echo "deb http://cran.wustl.edu/bin/linux/ubuntu xenial/" | sudo tee -a /etc/apt/sources.list
sudo apt update
sudo apt upgrade r-base r-base-dev
sudo apt update
sudo apt upgrade

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. If not, I highly recommend you install it via sudo apt install r-base-dev.

Step 3

Start a new R session and run the following:

update.packages(checkBuilt=TRUE, ask=FALSE)

Then you should be good to go.

Update: Linux Mint 19 and R 3.6.x

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.

The only difference is that instead of the command

sudo echo "deb http://cran.wustl.edu/bin/linux/ubuntu xenial/" | sudo tee -a /etc/apt/sources.list

you need to use

sudo echo "deb http://cran.wustl.edu/bin/linux/ubuntu bionic-cran35/" | sudo tee -a /etc/apt/sources.list

(replacing http://cran.wustl.edu/ with whichever CRAN mirror URL you chose in step 1)

I have updated this guide to use the full key out of security concerns (see here, for example).

Upgrade R version from 3.4.4 to 3.5.3 on Ubuntu 16.04

I would be surprised if there is a .deb available for this OS release/R release combination.

• This page only offers R 4.1, but as far back as 16.04 LTS
• This page offers older R versions, but only back to 18.04 LTS
• It's also possible that one of the backports on the Debian packages page would work on your system (it reports that 3.5.3 is available for Debian "jessie", although I have no idea how that lines up with Ubuntu releases).

I guess it's possible that one of those .debs works for your system though ... ? If you do install from .deb, you may have to be careful not to clobber your current version (e.g. using the --instdir argument to dpkg).

Building from source:

• download the source tarball for R 3.5.3
• untar, ./configure, make, sudo make install (assuming you have all the necessary development tools, system libraries, etc.; you'll have to troubleshoot/install as you go along)
  
  • It might be worth ./configure --prefix=/path/to/testdir to put the new version in a completely separate location, just to make extra-sure you don't stomp on your current install. (This would also simplify the library-path stuff below.)

Packages do need to be re-installed when switching major versions (e.g. 3.4.x to 3.5.x); one way to do it is to copy the system library of packages to a new place (adjust library paths as necessary; see R installation and administration manual).

Then, you should be able to update.packages(checkBuilt=TRUE, ask=FALSE) to update everything.

The tricky spots are (1) getting the library paths right (this will depend a bit on how things are set up in your existing installation; (2) it's conceivable that some current versions of packages on CRAN will fail to re-install/re-build under R 3.5.3. devtools::install_version() would help, although you'd have to track down the correct version manually. I recall someone posting about a package that would install an archived version by date, which could save a lot of poking around ...

How to update R from 3.x to 4.x and should I?

I did this a few weeks ago.

UpdateR didn't migrate the packages as expected, so that I had to do it manually :

• Install R 4.0.x
• Install RTools 4.0, take care to set $Path correctly as instructed. This new version is necessary for R 4.0 to compile from source some packages still in 3.x
• Migrate the packages from R 3.x to R 4.x :

# locate packages
.libPaths()
[1] "/Documents/R/win-library/4.0" 
# Migration list : replace previous 4.0 by 3.x in old_lib_loc
old_lib_loc <- "/Documents/R/win-library/3.x"
to_install <- unname(installed.packages(lib.loc = old_lib_loc)[, "Package"])
# Check if list is OK or if you want to clean up
to_install
[1] "abind"                "acepack"              "ada"                  "alphavantager"                   
[6] "ash"                  "askpass"              "assertive"            "assertive.base"       "assertive.code"  
# Migrate
install.packages(pkgs = to_install,Ncpus = 4) 

Packages still in 3.x are automatically recompiled from source.

That's it, no problems encountered since then.

How to upgrade R version on WSL?

It turns out that the version of r-base in the default Ubuntu repository is behind the newest version of r-base from CRAN.

The solution is to add R-CRAN to /etc/apt/sources.list, using the instructions here: https://cran.r-project.org/bin/linux/ubuntu/

sudo sh -c 'echo "deb https://cloud.r-project.org/bin/linux/ubuntu xenial-cran35/" >> /etc/apt/sources.list'
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
sudo apt-get update
sudo apt-get install --only-upgrade r-base  # This upgrades r-base if it's already installed; otherwise it doesn't install it

How to upgrade IRKernel in Ubuntu?

Basically, two steps should be taken:

1. Update R. These and that answers were a guideline.
2. Update IRKernel. The offical IRKernel instructions for Linux were useful.

Next, is described the complete procedure

1. Add Key to server

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9

2. Add Entry to sources.list

echo 'deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/' | sudo tee -a /etc/apt/sources.list

Depending on the linux you're using you should change, for example, bionic by xenial or cosmic, check out https://cran.r-project.org/bin/linux/ubuntu/README.html

3. Update Programs

According to the instructions in the above link, we should do the following:

sudo apt-get update
sudo apt-get install r-base
sudo apt-get install r-base-dev

4. Update /.local/share/jupyter/kernels/ir

type R in the console and follow the next steps according to this link

# In the console
R
# Inside R
install.packages(c('repr', 'IRdisplay', 'IRkernel'), type = 'source')
getRversion() # to verify the new R version
IRKernel::installspec()

This should show the following message:

[InstallKernelSpec] Removing existing kernelspec in /home/user_name/.local/share/jupyter/kernels/ir
[InstallKernelSpec] Installed kernelspec ir in /home/user_name/.local/share/jupyter/kernels/ir

As a final remark, you should remove the older version of R, which you can find in ~/R/x86_64-pc-linux-gnu-library, where you will now have two directories with two different versions or R (remove the older one).
