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
