There is a example for categorical data visualization from the following link:
packages "extracat" was required, author described the installation as:
"3 . In the terminal type the following command to install the extracat package: ` R CMD INSTALL -1 C:/Users/User/Desktop/Fluctuation extracat_1.7-6.tar "
But following the instruction, kept receiving error message, is there other way to install this package? Thank you!
What is the exact error message you are getting? Have in mind that the author is asking you to install an archived package with might not be even possible with the latest R versions.
You might need to downgrade R to the version the author was using at the time of writing.
Well, apparently you haven't install it correctly, or you don't have a suitable version since R can't find the make command. I recommend you to double check on that.
That version of RTools is for R >= 4.2, for your R version you need to install (and configure) RTools 4.0, although, it would be easier if you update your R version since it requires no manual configuration.
If you do update, have in mind that on Windows each R version gets its own package library so you would need to install package dependencies again for the new version.
