Make the set of default packages attached by R and Rscript the same(?) #44

Issue

Except for experienced R users, the following is often a surprising finding:

$ Rscript -e "loadedNamespaces()"
[1] "compiler"  "graphics"  "tools"     "utils"     "grDevices" "stats"     "datasets"  "base"     

$ R --quiet -e "loadedNamespaces()"
> loadedNamespaces()
[1] "compiler"  "graphics"  "tools"     "utils"     "grDevices" "stats"     "datasets"  "methods"   "base"

The above is with env var R_DEFAULT_PACKAGES not set/being empty.

Idea

When R_DEFAULT_PACKAGES is not set, the startup package could have an option to detect when Rscript is running and set the default to be the same as for R.
Add support for using R_DEFAULT_PACKAGES=+methods in ~/.Renviron.d/*?
...?

Is any of this a good idea?

HenrikBengtsson commented 6 years ago

In R-devel, Rscript will attach the same default packages as R (see https://github.com/wch/r-source/commit/c30ffef956b7fed993cbbd15feeb92313c3b89fa).
