In my.ls() you ought to convert the pos argument
to an environment and consistently use that environment
in the calls to eval, get, and ls in the function.
E.g., with the following modification
my.ls1 <- function (pos = 1, sorted = FALSE, envir = as.environment(pos))
{
.result <- sapply(ls(envir = envir, all.names = TRUE), function(..x)
object.size(eval(as.symbol(..x),
envir = envir)))
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),
envir = envir)))), "-------")
.ls
}
we get:
> sorted <- 10:1 # put a variable in .GlobalEnv that is also in my.ls*
> my.ls1()
Size Mode
my.ls 12,576 function
my.ls1 23,424 function
sorted 88 numeric
**Total 36,088 -------
> my.ls()
Size Mode
my.ls 12,576 function
my.ls1 23,424 function
sorted 48 logical
**Total 36,048 -------
