how do i use the get function to obtain an element from a list...
...t; was not found
i intend to do it inside a loop, using a new object (and hence, a new
name) for each iteration (i.e., instead of a$x, it would be a$1, a$2,
a$3, and so on, for a million times).
i would greatly appreciate it if someone could help me on this issue,
thanks in advance,

Well, this is what i got...

[1] -0.438163696867656
> (-0.0841219200008394)^(1/3)

alternative read.arff function for the package foreign
...an set a couple of parameters which can help me tune up my work
flow to better fit my needs (for example, reading only a limited number of
lines, since I just want to make a couple of fast tests and therefore, I
don't need the whole dataset).
Thanks for your time,
Juan Manuel

problem with save function
Hello list! i write because i'm having a strange problem with the "save"
function, here an example:
> x <- stats::runif(20)
> y <- list(a = 1, b = TRUE, c = "oops")
> save(x, y, file = "xy.Rdata")
> xy <- load("xy.Rdata")
> xy
[1] "x" "y"
why does this happens, when:
> x
[1] 0.96586833 0.60340508

address (nil), cause 'memory not mapped'
Dear users,
I got this problem and i don't have a clue of what it could be happening...
The context: i'm running a loop in which i extract information from a raster
map (I work with GRASS and R, using spgrass6 package), and rearrange it to
create a matrix. I've tried it with small maps and it works smoothly, but in
large maps I have to resort to saving data in the hard disk regularly
