I want to do a simple histogram for a very large data set. I traced the
problem to the range() function and the storage.mode()<-"double"
assignment.
Below is a sequence that works for min() and max(), but fails for range().
> length(evap0)
[1] 51812400
> mode(evap0)
[1] "numeric"
> storage.mode(breaks)
[1] "double"
> min(evap0)
[1] -2.254886e-05
> max(evap0)
[1] 0.0002331886
> range.default(evap0)
Error: vector memory exhausted (limit reached?)
> Error: vector memory exhausted (limit reached?)
> Error: vector memory exhausted (limit reached?)
I traced it to a parameter recursion in c() within range.default()
x <- c(..., recursive = TRUE)
I am running on a linux box with 8G memory, and
VENDOR=intel
OSTYPE=linux
MACHTYPE=i386
R : Copyright 2002, The R Development Core Team
Version 1.6.1 (2002-11-01)
I was able to do the histogram by removing the offending pieces of
hist.default(). But I do not have an explanation for the above failure.
I didn't find any plausible explanation in the archives.
Can someone help?
Thanks!
George
