A) I am not a Dr. I am just someone who has been using R for awhile. Since the
install process usually works for me, I might not even be the best person to
identify your problem, but I will help if I can.
B) sessionInfo is a function. You have to invoke functions by including
argument parentheses, like so:
sessionInfo()
Looking at how that function is implemented when you ask the interpreter to
print the function definition doesn't help us differentiate your setup from
anyone else's.
C) you have not addressed the question of what might be in your .Rprofile. That
is a file by that name in your home directory (My Documents?) If it does not
exist, it can't be a problem, but you need to confirm.
D) You have not addressed what might be corrupted in your personal package
library (typically My Documents\R\win-lib\3.3). Confirm that you have renamed
or deleted it.
E) It might be relevant to ask how you are installing the package. What was the
exact URL of the installation file? Did you make the mistake of using the "Run
As Administrator" option when you started that install file? (If so, that can
make it quite difficult to clean up bad file permissions. I am not even sure
how to fix that, so you would need someone else to help if so.)
F) What commands are you giving to R during your first run?
