The following package was uploaded to CRAN:
===========================================

Package Information:
Package: caretEnsemble
Version: 1.0.0
Title: Framework for combining caret models into ensembles
Use title case: see 'Writing R Extensions',
Author(s): Zachary A. Mayer [aut, cre], Jared E. Knowles [aut]
Maintainer: Zachary A. Mayer <zach.mayer@gmail.com>
Depends: R (>= 3.1.0), caret
Suggests: testthat, randomForest, rpart, kernlab, nnet, e1071, ipred,
   pROC, knitr, mlbench, MASS, gbm, klaR
Description: This package is built around 3 functions: caretList,

'This package' is redundant: what else might it be a description of?

   caretEnsemble, and caretStack. caretList is a convenience
   function for fitting multiple caret::train models to the same
   dataset. caretEnsemble will make a linear combination of
   these models using greedy forward selection, and caretList
   will make linear or non-linear combinations of these models
   using a caret model as a meta-model. Custom caret models are
   not yet supported. Multi-class classification and
   combinations mixing classification and regression models in
   one ensemble are also not yet supported.

Describe the package, not what it is not.

The maintainer confirms that he or she
has read and agrees to the CRAN policies.

Submitter's comment: This is a new submission to CRAN.  It is a package
   for creating ensembles of
caret models using greedy
   selection or other caret models.  It also has a
   helper
function for fitting many caret models to one
   set of re-sampled data.

# R CMD CHECK passes on:
##
   Mac (via `devtools::check()` on my local machine):
No
   error, warnings, or notes

## Ubuntu (via travis-ci
   on github)
No error, warnings, or notes

## Windows
   (via `devtools::build_win()`)
1 Note: New submission
   (maintainer) I think it is safe for me to ignore this

For you yes, not for CRAN.

The examples run for too long (see the policies):

* checking tests ... [215s/214s] OK
  Running ‘testthat.R’ [214s/214s]
