R help - Mar 2012 - Save/Load function()-result to file in a loop

Hi,

I am looking for a way to save the result of a function, e.g the lm()-function
to a file and reload it afterwards again. I'd like to do that in order to
minimize the used memory when running the function in a loop. The actual
function I want to store is the evaluate() from the dismo package.
I tried it with save() and load() but I am not sure if that is the way I should
do it as I don't get the result I desire...

ls <- list("A","B","C")
for(i in ls){
	x <- lm(c(1,2,3)~c(2,5,6))
	save(x, file = paste("/path/to/file_",i,sep=""))
}

A <- load("/path/to/file_A")

Load doesn't return the object you saved, but rather a character
vector with the name of that object, here "x". So you would do
something like

load("/path/to/file_A")
x # Here's your data

or more robustly

get(load("/path/to/file_A"))

See ?load (value) for details.
