The above seems very awkward. If you want to do it temporarily each
time you use R its going to be MUCH slower than using batch files
since you will have to start up R and then run an R program.  To do it
permanently implies mucking with  your system settings and leaving it
in a changed state and that seems worse than the batch file approach
which requires no such permanent change.  Your (2) is unnecessary
using the batch files since they automatically find R regardless of
what you name the directory.  In other situations if you want to set
the path using R you already need to know the path to R in order to
run R in the first place and if you know the path to R in order to run
it why do you need to set the path?
