This is one of the more comprehensive threads and discussions on these topics I have located to date.
How to find out which package version is loaded in R?
Nonetheless, I am finding this has not provided me with sufficient information to ensure I have installed and loaded the two packages I must have before I can begin to expect R to function properly. These packages are: Rserve (1.8-0) and MASS (7.3-45).
It seems answers to these topics can be application dependent or, perhaps purpose driven is a better phrase to use. Unfortunately, the R documentation will confuse you so, I thought it best to solicit the input of more experienced users.
I am working on a personal laptop with R 3.5.1 and Win7 Pro. It is clear from the r documentation that Windows is not the best or preferred environment for R.
despite a lot of work something remains missing and I have been unable to identify what it is.
