Hi,

What platform are you using, 64 bit? What kind of dataset? What kind of 
operation do you want to perform on the data? Quite a lot has been said 
on memory usage in R on the "normal" R-help list. Googeling for "R-help 
memory limit" gives tons of information on memory issues. There is bound 
to be something there for you.

cheers,
Paul

HI Users,

I must processing a large data set in R and I wish improve my PC memory. I
have a Windows Vista with 4 Gb di RAM and Intel centrino 

In ordinary modality my memory is this

memory.size(TRUE)

[1] 13.4375

memory.size()

[1] 11.01423

If I use the command line "C:\program files\R\R-2.7.1\bin>Rgui.exe
--max-mem-size=2048M"

memory.size(TRUE)

[1] 13.4375

memory.size()

[1] 11.01418

vegetation <- read.delim("vegetation_2674147_2684147.txt",

sep=",",header=TRUE)

coordinates(vegetation) =~X+Y

Error: cannot allocate vector of size 232.5 Mb

Is there a solution of this limitation?

ale
