Vectorization helpers

Breaks vectorize

Quantile breaks

Quantile vectorize by integer helper

Quantile vectorize by probabilities vector helper

## Usage

```
calculate_breaks(mraster, breaks)
calculate_quantile_breaks(mraster, nStrata)
quantile_breaks_integer(mraster, nStrata)
quantile_breaks(mraster, nStrata)
```

## Arguments

- mraster
Spatraster. Raster to stratify. Layers in

`mraster`

must match the number of`breaks`

vectors provided.- breaks
Numeric. Vector of breakpoints for each layer of

`mraster`

. If`mraster`

has multiple layers,`breaks`

must be a list with an equal number of objects.- nStrata
Numeric. A positive integer representing the number of desired classes or a numeric vector of probabilities with values between

`0-1`

. If`mraster`

has multiple layers,`nStrata`

must be a list with an equal number of objects.
