Hi all,
I've read the R for windows FAQ and am a little confused re:
memory.limit and memory.size
to start using R 2.6.2 on WinXP, 2GB RAM, I have the command line "sdi
--max-mem-size=2047M"
Once the Rgui is open, memory.limit() returns 2047, memory.size()
returns 11.315, and memory.size(max=T) returns 19.615
Shouldn't memory.size(max=T) return 2047?
Upon running several operations involving kriging (gstat package,
original data file 3 variables, 12000 observations)
the program runs out of memory
"memory.c", line 57: can't allocate memory in function m_get()
Error in predict.gstat(fit.uk, newdata = EcoSAV.grid.clip.spxdf,
debug.level = -2, :
m_get
Immediately following this,
memory.limit() returns [1] -Inf
Warning message:
In memory.limit() : no non-missing arguments
to max; returning -Inf
memory.size() returns 24.573.
memory.size(max=T) returns 46.75
To my untrained eye, it appears that R is not being allowed access to
the full memory limit specified in the cmd line....if this is the case,
how does one ensure that R is getting access to the full allotment of RAM?
Any insight is appreciated...
