class_pred: Create a class prediction object

In topepo/probably: Tools for Post-Processing Predicted Values

Create a class prediction object

Description

class_pred() creates a class_pred object from a factor or ordered factor. You can optionally specify values of the factor to be set as equivocal.

Usage

class_pred(x = factor(), which = integer(), equivocal = "[EQ]")

Arguments

x	A factor or ordered factor.
which	An integer vector specifying the locations of x to declare as equivocal.
equivocal	A single character specifying the equivocal label used when printing.

Details

Equivocal values are those that you feel unsure about, and would like to exclude from performance calculations or other metrics.

Examples

x <- factor(c("Yes", "No", "Yes", "Yes"))

# Create a class_pred object from a factor
class_pred(x)

# Say you aren't sure about that 2nd "Yes" value. You could mark it as
# equivocal.
class_pred(x, which = 3)

# Maybe you want a different equivocal label
class_pred(x, which = 3, equivocal = "eq_value")
