Apply detectCharacterType over an entire matrix

This function detects whether each column in a matrix is a continuous (e.g., with values 2.45, 9.35, and so on) or a discrete character (e.g., with values blue, red, yellow).

Usage

detectAllCharacters(mat, cutoff = 0.1)

Arguments

mat

A matrix of data

cutoff

Cutoff value for deciding if numeric data might actually be discrete: if nlev is the number of levels and n the length of dat, then nlev / n should exceed cutoff, or the data will be classified as discrete

Value

Vector of either "discrete" or "continuous" for each variable in matrix

Examples

data(anolis)
detectAllCharacters(anolis$dat)
#>  [1] "discrete"   "continuous" "continuous" "continuous" "continuous"
#>  [6] "continuous" "continuous" "continuous" "continuous" "discrete"  
#> [11] "discrete"
