[R] Memory Problem

[jim holtman]

Here is a function I use to get the size of the objects in my
workspace.  Let us know the output of this command

my.object.size <- function (pos = 1, sorted = F)
{
    .result <- sapply(ls(pos = pos, all.names = TRUE), function(..x)
object.size(eval(as.symbol(..x))))
    if (sorted) {
        .result <- rev(sort(.result))
    }
    .ls <- as.data.frame(rbind(as.matrix(.result), `**Total` = sum(.result)))
    names(.ls) <- "Size"
    .ls$Size <- formatC(.ls$Size, big.mark = ",", digits = 0,
        format = "f")
    .ls$Mode <- c(unlist(lapply(rownames(.ls)[-nrow(.ls)], function(x)
mode(eval(as.symbol(x))))),
        "-------")
    .ls
}


You will get something like this:

> my.object.size()
                 Size        Mode
.my.env            28 environment
.Random.seed    2,528     numeric
.required          72   character
my.object.size  6,712    function
x               6,712   character
**Total        16,052     -------
