Problems with installing ggplot2 and interactions in R

I wanted to use the packages ggplot2 and interactions. I first installed interactions and then ggplot2. However I got error messages because I did not have the newest version of ggplot2.
I tried updating ggplot2, which repeatedly did not work. So I deinstalled it and tried reinstalling it. Now I can't even install it again and "interactions" doesn't work either.
I don't understand what I did wrong, because I could install it the first time.

Ihis is the error message I get, when trying to install ggplot now:

1. I installed rtools. However the error saying that rtools is needed didn't disappear.
2. I tried updating rslang. however every time I tried to update it, it just shows the old version afterwards. I'm too scared to uninstall it, because of what happened with ggplot2.

LEK, it seems from here:

> removing 'C:/Users/ErikNB/Documents/R/win-library/4.0/ggplot2'

that you are not using the latest version of R itself, which is actually 4.3.1 ---> https://www.r-project.org/

I would start from scratch by installing the latest version of R, if 4.0 is not a must, and then trying again to install interactions and ggplot2 packages.

Like Fede B said: I needed the newest version of R. Just installing it from Rstudio did not work, i had to deinstall all older versions of r before i could use the new one. I had to reinstall almost all of my packages, but i had no problem with "ggplot2" and "interactions" anymore! Thank you.
