Data scientist and graduate student in CS at UIUC checking in here. Just wanted to thank you for this clear video. It is hard to come across such clear videos with R! Thank you!

Thank you. You hit the nail on the head.

thank you, excellent. It's a new package (leaps) and versatile. From here can we pipe this information for prediction as well as generating ROC and AUC with bootstrapping. If there are any good packages that could be used with 'leaps' package please let us know, Another question is if you have to say around 100 variables and you want to select the top 10 or 20 best predictors can this package will be able to do it. Thank you again.
