Is there an easy way to sperate categorical vs continuous variables into two dataset in R

Is there an easy way to sperate categorical vs continuous variables into
two dataset in R

Say i have about 500 variables available, I'm trying to do variable
selections, for my model ( response is binary )
I am planning on doing some kind of corr analysis for all continuous, then
, do categorical after.
Since there's a lot of variables involved, I can't do it manually.
Is there a function that I can use ? or maybe a module ?
Please let me know. Thanks
