Hi everyone,



I’ve recently added a private library as a way to manage my R libraries. And
I did this by simply copying my old library to a new folder and then linking
this to R by setting my R_LIBS  environmental variable in .Renviron.



However I have run into a problem.



When I update my packages it is not updating those that are current in the
base R library.



This means I can’t load packages that are included in base R, since R is
looking in my private library first and when it finds the package it tries
to use it. But it’s an outdated version.



The easiest solution I can think of is to update both libraries, but when I
run update.packages(lib.loc=”private library location” ask = FALSE,
checkBuilt=TRUE) it’s not updating them.



So I was wondering if there is a way to update all packages  that occur in
all libraries?





(Note that I can think of other solutions to my problem, but they are all
time consuming and defeats the purpose of why I want a private library i.e.
it makes updating R easier since I don’t need to copy over the library
folder each time nor update any environmental variables. So far the best
alternative I’ve come up with is to delete all the duplicate base R
libraries from my private library)



If anyone is interested the code I used to understand my problem is below.





Thanks everyone

Foreign package won’t load

> library(foreign)

Error: package 'foreign' was built before R 2.10.0: please re-install it



> .libPaths()

[1] "C:\\Program Files\\R\\library"   "C:/PROGRA~1/R/R-212~1.0/library"



> .libPaths("new")



> .libPaths()

[1] "C:/PROGRA~1/R/R-212~1.0/library"



Foreign package will load

> library(foreign)
