[R] PythonInR. Python script in R with parameters required. Download satellite images from NASA

[Collin Lynch]

Magi, is there a reason that you need to run the script via R? If your
plan is to download the data via python than then process with R, you
might consider using the Rpy2 package to link them.  This would allow
you to call the downloading code from python and then have python feed
the data to R.
