Create a factor variable and include unobserved levels for compatibility with model prediction functions

Usage

superFactor(x, fullLev)

Arguments

x	a vector to be converted to a factor
fullLev	a vector of factor levels to be assigned to x

Value

a factor variable with all observed levels of x and all levels of x in fullLev

Examples

regularFactor <- c("A", "B", "C")
regularFactor <- factor(regularFactor)
levels(regularFactor)
# Now make it super
newLevs <- c("D", "E", "F")
regularFactor <- superFactor(regularFactor, fullLev = newLevs)
