I have a quick question about the swirl package. Do I need to install this package every time I need to run it? So far that's what I have been doing. Is there any way I can save the package in Rstudio so that I don't have to install it all the time?
You only need install once, that makes swirl package installed in R (but has not been called to be used)
To call that when you want to use it, type library(swirl). And yes, you should call it everytime you start new session in R Console
