[R] Installation Re: Problems with library...

[Medic]

1. Jeff, thank you for your explanation!
<Jeff Newmiller: It means that one of the packages installed during R
installation is damaged>
2 Kum-Hoe, thank you for appointed treatment!

QUESTION!
I will also (with R) reinstall the RStudio. Allow me to ask a QUESTION
(about packages installing) -- which variant is right:
1) installing all packages only in R (RStudio will take them automatically)
2) installing all packages only in RStudio (R will take them automatically)
3) installing all packages in R and in RStudio (i.e. in each of them)
Thanks, Medic
