Subject: R memory limits and good memory management
Hello,
I am not fluent in computer hardware or software development so I will try
to be as precise as I can. I am going to build some R routines to analyze
large intraday financial data sets. For this project I think that I
need be concerned
about R memory limits and good memory management/practices. The following
R help
page states that the limit on individual objects (a vector) is around 200
million elements.

What about data frames? And I suppose that I need to be aware of the
objects in the working memory (overwrite as many objects as possible)?
Note, I am new to the issue of good memory management. Any specific
details on R memory and good practical advice are welcomed.
Thanks,
Chad R. Bhatti
