outcome2factor: Convert numeric ternary outcomes into a factor

Description

Convert numeric ternary outcomes into a factor

Usage

outcome2factor(x, n.levels = 3L)
threshold2factor(x, n.levels = 3L, threshold = 0)

Arguments

x

a numeric vector of -1, 0, and +1 values, indicating downregulation, uncertain response or upregulation, or a numeric vector that can be converted into such values using a pair of thresholds.

n.levels

numeric Number of levels to create, either 3 or 2.

threshold

numeric vector Range enclosing the values to be considered uncertain.

Details

These functions convert the numerically encoded values into a factor with the three levels "down", "uncertain" and "up", or into a factor with two levels de and uncertain as expected by default by scales scale_colour_outcome, scale_fill_outcome and scale_shape_outcome. When n.levels = 2 both -1 and +1 are merged to the same level of the factor with label "de".
