Hi everyone -
I'm trying to do a forward stepwise regression (I've tried both step
and stepAIC) inside of a function. I can do it outside the function
with no problems (first example in code below). I can also do a
backward stepwise regression inside a function (second example), but

Setting A <- NULL doesn't immediately release the memory, the memory is
actually released in gc(), which R calls for you at some "random" time.
In situations like this I explicitely call gc() and do not wait for R to
do this, e.g
A <- NULL; gc()
Hope this helps,

Works fine when you give as.Date() a character vector. I suspect the Date
column in your data frame is a factor.
