Rers:
I installed R 2.9.0 from the Debian package manager on our amd64
system that currently has 6GB of RAM -- my first question is whether
this installation is a true 64-bit installation (should R have access to
> 4GB of RAM?) I suspect so, because I was running an rqss() (package
quantreg, installed via install.packages() -- I noticed it required a
compilation of the source) and watched the memory usage spike to 4.9GB
(my input data contains > 500,000 samples).
With this said, after 30 mins or so of processing, I got the
following error:
tahoe_rq <-
rqss(ltbmu_4_stemsha_30m_exp.img~qss(ltbmu_eto_annual_mm.img),tau=.99,data=boundary_data)
Error: cannot allocate vector of size 1.5 Gb
The dataset is a bit big (300mb or so), so I'm not providing it
unless necessary to solve this memory problem.
Thoughts? Do I need to compile either the main R "by hand" or the
quantreg package?
