R: Turns a factor into a number

fac2num {dendextend} | R Documentation

## Turns a factor into a number

### Description

Turning a factor into a number is not trivial. Using `as.numeric` would only return to us the indicator numbers and NOT the factor levels turned into a number. fac2num simply turns a factor into a number, as we often need.

### Usage

    fac2num(x, force_integer = FALSE, keep_names = TRUE, ...)

### Arguments

`x` | an object.
`force_integer` | logical (FALSE). Should the values returned be integers?
`keep_names` | logical (TRUE). Should the values returned keep the names of the original vector?
`...` | ignored.

### Value

if x is an object - it returns logical - is the object of class dendrogram.

### Examples

    x <- factor(3:5)
    as.numeric(x) # 1 2 3
    fac2num(x) # 3 4 5
