detectAllCharacters: Apply detectCharacterType over an entire matrix
Description
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
