A step by step (screenshots) tutorial for upgrading R on Windows

s05

tl;dr

If you are running R on Windows you can easily upgrade to the latest version of R using the installr package. Simply run the following code:

# installing/loading the latest installr package:
install.packages("installr"); library(installr) # install+load installr
 
updateR() # updating R.

Running “updateR()” will detect if there is a new R version available, and if so it will download+install it (etc.). just press “next”, “OK”, and “Yes” on everything…

A GUI interface to updating R on Windows

Starting from installr version 0.15.0, the upgradingprocess can be done with a click-on-menus GUI interface. Here is how to use it.

Step 1: load installr

# installing/loading the latest installr package:
install.packages("installr") # install installr
library(installr) #load

Step 2: pick “update R” from the new “installr” menu

Step 3: installr will check and detect that there is a new version of R for you – click “OK”

s03

Step 4: if you wish to check the NEWS of the new R version – click “Yes” and a browser window will open up with this information

s04

Step 5: if you want to download and install the latest R version, press “Yes”

s05

Step 6: wait for R to download

s06

Step 7: press “next” in R’s installation wizard

s07

Step 8: wait R finishes to get installed

s08

Step 9: Press “Yes” to copy your packages to the new R installation (press No, if you intend to use the “global R library folder” strategy)

s09

Step 10: to keep package in your old R folder, press “Yes” (this is safest)

s10

Step 11: wait while the packages get copied

s11

Step 12: you can also have Rprofile.site be copied automatically to the new location

s12

Step 13: you may press “Yes” to get update packages in the new R installation

s13

Step 14: if you have a firewall, R may ask to get access to the internet

s14

Step 15: while the packages are updated, you will need to wait. A hidden Rscript process will run in the background and update the packages

s15

Step 16: once it is all done, you will be offered to quit R (sure, why not)

s16

 

That’s it.

Feedback

I try to keep the installr package updated and useful, so if you have any suggestions or remarks on the package – you are invited to leave a comment below, or report an issue on github.

  1. In my experience:

    In Windows 10 the packages copied from the old R are not allowed by Microsoft to be pasted into the new R.
    The subdir library in the new R is not writable and remains so during updating using the R-scripts.
    Therefore, the packages in the old R should be copied/pasted by the administrator self, carefully not overwriting existing new packages in the new R.
    All packages to be updated by R-script from within the new R can be downloaded in a C://?win-library and from there firstly unzipped and then copied/pasted by the administrator self into the new R library subdir

    I wonder if it works better using the installr menu in the Rgui R Console
