Hi all

I am very new to R (few days old but need it for my PhD)

I am struggling to install certain packages, specifically the Rcmdr package and it comes up with this error:

WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:

https://cran.rstudio.com/bin/windows/Rtools/
Warning in install.packages :
package ‘Rcmdr’ is not available (for R version 3.2.2)

I then tried to install Rtools and it came up with this error:

WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:

https://cran.rstudio.com/bin/windows/Rtools/
Warning in install.packages :
package ‘Rtools’ is not available (for R version 3.2.2)

Can someone please just explain what I can do to fix this and what the system is actually saying?

R 3.2.2 is a very old version of R. Some packages do not work with old versions.

If you can, I would strongly advise updating to the latest version of R (4.0.2)

Thank you so much for your feedback, you have no idea how much I appreciate you helping me

Please forgive my ignorance, but how do I update R and R studio to the latest ones? I know I need to download everything, but how do I link my R Studio to the latest R package I have? And where can I download the latest packages of both of these?

You can install R from https://cran.r-project.org/

I think Rstudio should automatically find the new version of R. You can check for updates to Rstudio from the help menu with check-for-updates (see https://support.rstudio.com/hc/en-us/articles/203842428-Getting-the-newest-RStudio-builds)

Also, be aware that Rcmdr is no longer compatible with RStudio (at least till last time I checked) so if you are going to use it you have to launch it from the R GUI instead.

Thank you so much for helping me

What is the R GUI?

#7

Is the Graphical User Interface you get when you install R.

#8

Where would I find the Graphical User Interface?

#9

Rcmdr works for me in Rstudio, so it is worth trying before you starting to use R directly. The R GUI will be in the folder where R installs.

For what it's worth, I've never found Rcmdr very useful as a teaching tool.

#10

You are right, I checked and the latest version of Rcmdr is RStudio compatible again.

#11

Thank you so much, I was able to install it with the latest R version

Really appreciate all the help this forum gave me, thank you so much
