...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, Juan Manuel Barreneche, Zoolog?a de Vertebrados, Facultad de Ciencias, UDELAR, Uruguay.

Well, this is what i got... > -0.0841219200008394^(1/3) [1] -0.438163696867656 > (-0.0841219200008394)^(1/3) [1] NaN and i don't have a clue of why this happens or how to avoid it, any suggestions? thank you, Juan

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

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
