fsInclude: Select Features by Explicit Reference
In exprso: Rapid Deployment of Machine Learning Algorithms

fsInclude selects features passed to the include argument. Ranks features by the provided order.

1	fsInclude(object, top = 0, keep = 0, include)

`object`	An `ExprsArray` object to undergo feature selection.
`top`	A numeric scalar or character vector. A numeric scalar indicates the number of top features that should undergo feature selection. A character vector indicates specifically which features by name should undergo feature selection. Set `top = 0` to include all features. A numeric vector can also be used to indicate specific features by location, similar to a character vector.
`keep`	A numeric scalar. Specifies the number of top features that should get returned by the feature selection method. Use of `keep` is generally not recommended, but can speed up analyses of large data.
`include`	A character vector. The names of features to rank above all others. This preserves the feature order otherwise. Argument for `fsInclude` only.
