A common misconception. R uses *virtual* memory for its data: the OS decides where to allocate that (RAM, disc, both). R has no 'memory limit': see ?'Memory-limits' (including limits which can be set on Windows, if this is Windows). A guess: this is Windows and the OP did not read http://cran.r-project.org/bin/windows/base/rw-FAQ.html#There-seems-to-be-a-limit-on-the-memory-it-uses_0021
64 bit)? How big is your data; you did not provide much information about your problem. Depending on what you what to 'sort', there might be other ways of doing it. This gets back to my tag line: "Tell me what you want to do, not how you want to do it". On Mon, Mar 11, 2013 at 11:20 AM, Jie <jimmycloud at gmail.com> wrote:
Dear All, I have a long sequence and want to find the quantile, or sort it first. It seems sort() or quantile() reaches the memory limit. Is there a way to allocate more memoy on SSD for R when startup, so that R can use both RAM and hard drive space? Thank you. Best wishes, Jie
