FSATeach depends on R 3.0.0 or greater and several packages being installed for your R. FSATeach is not distributed from CRAN; thus, you can install FSATeach and all required other packages by running the line below in your R.
[Note: If you have not previously identified a CRAN mirror site then you will be prompted to do so. This prompt may be 'buried' under other open windows.]
There should be no errors from running the previous code. However, type the following two lines into R to see if FSATeach is working properly.
Packages available through CRAN that are installed in this process are shown below. In some instances you may have to install these manually as well.
The code from the sourced file above can be viewed in this file.
Note About Using Macs
The FSATeach package uses TCL/TK for some interactive plots. Some Mac users report problems with using TCL/TK. While I am not a Mac user, nor do I have access to a Mac to test these issues, I have had some students report success installing the tcltk universal build located here (direct link to the file). You may have to re-install the FSATeach package using the source() line above after installing this file.
