How do I Load a Package?
RProvider discovers the packages installed in your R installation and makes them available as packages under the RProvider root namespace. The actual package is lazily loaded the first time you access it.
How do I install a new Package?
Currently you need to load up a real R session, then install the package via install.packages, or the Packages/Install Packages... menu. You will then need to restart Visual Studio because the set of installed packages is cached inside the RProvider.
I have a package installed and it is not showing up
The most likely cause is that RProvider is using a different R installation from the one you updated. When you install R, you get the option to update the registry key
HKEY_LOCAL_MACHINE\SOFTWARE\R-core to point to the version you are installing. This is what RProvider uses. If you are running in a 32-bit process, RProvider uses
HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\InstallPath to determine the path. For 64-bit, it reads
HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R64\InstallPath. When you install a package in a given version of R, it should be available in both the 32-bit and 64-bit versions.
Function and Package names
There are a couple of mismatches between allowed identifiers between R and F#:
Dots in names
It is pretty common in R to use a dot character in a name, because the character has no special meaning. We remap dots to underscore, and underscore to a double-underscore. So for example, data.frame() becomes R.data_frame().
Names that are reserved F# keywords
Some package and function names are reserved words in F#. For these, you will need to quote them using double-backquotes. Typically, the IDE will do this for you. A good example is the base package, which will require an open statement where "base" is double-back-quoted.
