Here is a script that will find all the atomic objects of length 1 and
put them in a dataframe that you then use to determine what variables
are there.

Everyone is assuming I know what the output data are, or that they come
out from my model in some easily called vector. But I don't, and they do
not. The outputs are hidden, and all are separate variables that need to
be called. Also which ones come out after a given run will vary each
time. Al
Here is a function that might do what you want:
> # function to create the output
> f.output <- function(dat){
+ # create the base output vector
+ output.base <- rep(NA,10)
+ names(output.base) <- paste("var", 1:10, sep='')
+ output.base[names(dat)] <- dat
+ output.base
+ }

Steve
Is this the sort of thing you mean?
output <- character(26)
names(output) <- paste('var', LETTERS[1:26], sep='')
output
output[paste('var'

Let's say I have a program that returns variables whose names may be any
string within the vector
NAMES=c("varA","varB","varC","varD","varE","varF"..."varZ"), but I do
not ever know which ones have actually been created. So in one example
output, "varA", "varC", and "varD" could exist, but in a
10 matches
