The caret package (short for Classification And REgression
Training) attempts to streamline the process for creating
predictive models. The package contains tools for:
- data splitting
- pre-processing
- feature selection
- model tuning using resampling (with parallel processing)
- variable i

It is difficult to tell what the problem is without the data (or a
reproducible toy example), but it seems like you are trying to remove NA

in try?

Three more packages will be showing up on your mirror soon.
The caret package (short for "Classification And REgression Training")
aims to simplify the model building process. The package has functions
for
- data splitting: balanced train/test splits, cross-validation and
bootstrapping sampling

You make a good point about what would need to be done for these data,
that wasn't the objective of the graphic.

There aren't many. Look at
