# Apply detectCharacterType over an entire matrix

Source:`R/detectCharacterType.R`

`detectAllCharacters.Rd`

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).

## 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

## Examples

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