Re: [R] loading into a list

[Roger D. Peng]

I can think of two possible solutions.  One is to load the .Rdata file 
into an environment and then use the $ and [[ operators to access 
elements.

> x <- 1; y <- 2
> save(x, y, file = "xy.RData")
> e <- new.env()
> load("xy.RData", envir = e)
> rm(x, y)
> e$x
[1] 1
> e$y
[1] 2
Another way, if you really want a list, is to load into an environment 
(or the workspace) and use mget,

> e <- new.env()
> load("xy.RData", envir = e)
> mget(c("x", "y"), e)
$x
[1] 1
$y
[1] 2
Both of these only work in R >= 1.9.0.

I have the following problem.

Use the same algorithm (with different parameters) to generate
simulation results.  I store these in variables, eg A, B, C, which I
save into a file with
save(A, B, C, file="solution001.Rdata")

I do this many times.  Then I would like to load the above, but in
such a manner that A, B, C woule be part of a list, eg
sol001 <- loadIntoList("solution001.Rdata")

so that sol001 is a list with elements A, B, C.

I am looking for a way to implement the above function.  The variables
are very large and I need a lot of time to compute them, so saving &
loading the results is the only viable alternative.
Thanks,

Tamas
