fsStats: Select Features by Statistical Testing

In exprso: Rapid Deployment of Machine Learning Algorithms

Description

fsStats selects features using a base R statistics function (toggled by the how argument).

Usage

fsStats(object, top = 0, keep = 0, how = c("t.test", "ks.test",
  "wilcox.test", "var.test"), ...)

Arguments

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.
how	A character string. Toggles between the "t.test", "ks.test", "wilcox.test", and "var.test" methods.
...	Arguments passed to the detailed function.

Value

Returns an ExprsArray object.
