Does RStudio allow me to toggle between R versions? (I'm running RStudio Version 1.1.383)
I don't see anything in preferences->general or preferences->code
Or, can I specify an R version from the command line at startup?
I'm trying to resolve an incompatibility problem:
install.packages("rethinking")
Installing package into ‘/Users/rcphelps/Library/R/3.3/library’
(as ‘lib’ is unspecified)
Warning in install.packages :
package ‘rethinking’ is not available (for R version 3.3.3)
