[R] trends regarding memory limitations for R use under Linux
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

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.
