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".

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
