You have solved my question!
I don't know how to reply your message, so I have added thanks messag to this post instead.
Hello, I am a student currently started using R in my university's class.
I have been trying to install "plot_model" by putting texts as [install.packages("plot_model")] into script, however, it is impossible. Instead, these following messages showed up on the console:
Warning in install.packages :
package ‘plot_model’ is not available for this version of R
A version of this package for your version of R might be available elsewhere,
see the ideas at
I have accessed into the above page, but I have no idea where I should see.
This may be because of my poor English, though.
I am assigned homework which requires to use "plot_model" and actually my colleagues have no problem.
