Hello, I am aware of possibilities to extend memory, for the R language, under Windows. Since I read it is not the case under Linux, I would like to know up to which size R can handle matrices. The RAM limitation of my PC is 4 G0. I thank you in advance for any indication on the subject. Best regards, Christine Sinoquet

Then a completely filled memory with doubles (i.e. 8 byte floating point numbers) is 4*1024^3/8 (if you have a 64-bit OS). But in order to do something, the objects should not take more than 1/3 of your available memory. Hence a matrix with 4*1024^3/8/3 elements seems to be a reasonable upper limit. Uwe Ligges
