Is there a way to start multiple instances of R in an automated manner?
Since I'm not sure that question makes tons of sense, here's my scenario:
I have a number of data updates that need to be completed on an ongoing
basis with the data pulled from and then stored to another location. The
updates are manually triggered, so can build up in terms of the volume that
needs to be updated.
The updates can take a lot of time if I run everything from within a single
Rgui, but it isn't a big deal if there aren't a lot of accumulated updates
that need to be run.
But say if I have a week or a month's worth of accumulated updates to run,
this takes a LOT of time in a single Rgui. If I split it up, I can run it
on 6 Rgui's (I'm in windows 7 with an 8 Core machine) and increase my
overall efficiency. But this requires manual intervention as there are
steps before (that figure out how big the updates that must be run are) and
then steps after that summarize and give me some metadata.
What I would love is something that will execute within an existing Rgui
and allows me to send a command (such as source( "myfile.R" ) to a new
Rgui. Does such a command even exist or is this just wishful thinking?
I'm trying to avoid writing a wrapfile in another language which would be
able to source the .R file as most of this (before and after the ideal
split point) is written in R already.
(FWIW Windows 7, 8 core machine running 64bit R)
Thanks,
Brigid
