[R] Yet another memory limit problem

[Tim Clark]

Thanks for everyones help - mydat was not what I thought it was.  str(mydat) 
showed:
 $ Date       : Factor w/ 1504 levels "","2002-11-22",..: 295 295 295 295 295 
295 295 295 295 295 ...
 $ Time       : Factor w/ 72447 levels "","00:00:00",..: 15423 15470 15509 17112 
17136 17159 17209 17239 17266 21527 ...
 
I didn't properly convert date and time using chron.  Not sure how R plots 
factor levels, but obviously it has problems with it!

Aloha,

Tim

That shouldn't by itself cause concern. It is always the _last_
allocation that triggers the message, so it could happen due to
allocation of 3 vectors of size 800M. Straw, camel, back...

Another matter is that memory.size is the amount _used_, not amount
_available_, so you would seem to have more like 1500M left.

However, it does look odd that mydat with dimensions 245x9 should
generate an 800M memory request. As others have suggested, perhaps mydat
is not what you think it should be...
