R help - Feb 2014 - problem of calculate mean value of large time series data

Hi,


I have 20,000 time series variants whose length is about 3000 , and i need to
calculate the mean value of each variant. I invoke R with a java client named
RCaller, and I assigned the values of these time series variants using RCaller.


The problem is : After I start running, the java program hangs.


The program seems ok with small size of data.


Could anyone help me with this?


Thanks 


Hellen

If all you want is the mean, why not do it in Java? That sounds like a half
gigabyte of memory in the best case, and you are trying to move it around from
process to process, making copies here and there. If you are on 32 bit OS then
that will fragment your memory pretty quick.

Anyway, you should read the Posting Guide... HTML email should be plain text, no
reproducible example, no sessionInfo... plenty of "opportunities for
excellence" here.
