[R] Running R at a specific time - alternative to Sys.sleep() ?

[Tony Breyal]

Thank you kindly Jim, that works great for me!

For anyone who does a search on this topic and finds this post, the
two web pages I used to further investigate Jim's suggestion were the
following (i did not know what a batch file was, or that you could use
windows task scheduler on them):

task scheduler - http://www.iopus.com/guides/winscheduler.htm
batch files - http://www.statmethods.net/interface/batch.html

I was able to write the batch file as a text document, and then after
saving it, changed the extension for '.txt' to '.bat'

Cheers,
Tony Breyal
