Return function from function with minimal environment
...elates to the question "How to set a former environment?" asked
yesterday. What is the best way to to return a function with a
minimal environment from a function? Here is a dummy example:
foo <- function(huge) {
scale <- mean(huge)
function(x) { scale * x }
}
fcn <- foo(1:10e5)
The problem with this approach is that the environment of 'fcn' does
not only hold 'scale' but also the memory consuming object 'huge',
i.e.
env <- environment(fcn)
ll(envir=env) # ll() from R.oo
# member data.class dimension object.size
# 1 huge numeric 1000...

geom_plot creates Area Instead Of Lines
Hi,
I have created a large (?) data frame. I have one variable to plot, lets
call it X. further X has been observed under conditions Y, Z. And the
observation took place at times T (0:10e5). Now my data frame D consists of
x,y,z,t each corresponding to the combination of X, Y, Z and T. I would
like to create different plots and use this:
h <- ggplot(D, aes(y=x, x=t))
h + geom_line(data=subset(subset(D,y=someThing),z=thingSome))
+geom_line(data=subset(subset(D,y=someThingElse),z=...

Hi to all.
I'm experimenting with running a

Possible?

Because Nvidia did not list drivers for this architecture, I'm
experimenting with a nouveau driver.

slow computation of functions over large datasets
Hello there,
I’m computing the total value of an order from the price of the order items
using a “for” loop and the “ifelse” function. I do this on a large dataframe
(close to 1m lines). The computation of this function is painfully slow: in
1min only about 90 rows are calculated.
The computation time taken for a given number of rows increases with the
size of the dataset, see the example with
