25 # this same set of packages by simply overriding its version of R
26 # with the wrapped one, however, RStudio internally overrides
27 # R_LIBS_SITE. The below works around this by turning R_LIBS_SITE
28 # into an R file (fixLibsR) which achieves the same effect, then
29 # uses R_PROFILE_USER to load this code at startup in RStudio.
