[R] creating a list of lists

[Paul Boutros]

Hello,

I'm trying to create a series of randomForest objects, basically in a  
loop like this:

forests <- list();

for (level in 1:10) {

          # do some other things here

	# create a random forest
	forest <- randomForest(
		x = x.level,
		y = z.level,
		ntree = trees
		);

	forests <- c(forests, forest);

	}


But instead of creating a list of 10 forests, this creates a list of  
180 elements, 18 for each forest.  Is there a way to create a list of  
randomForest objects for use later on in code like:

for (forest in forests) {
         values <- predict(forest, data);
         # do things with these predicted values
         }

Sincerely,
Paul
