Hello all, 

So I am using the (formula entry) method for randomForests:

randomForest(y~x1+x2+...+x39+x40,data=xxx,...) but the issue is that some of
the items in that package dont take a formula entry - you have to explicitly
state the y and x vector:


Now my question is whether there is a function/way to tell R to take a
formula and make the two corresponding datasets [x,y] (that way I dont have
to create the x dataset manually with all 40 variables I have).

There must be a more elegant way to do this than
