Helper for setting Raster or `SpatRaster` colors

Description

This is a wrapper to help with migration to terra. Currently can only be used for a single layer SpatRaster or a RasterLayer.

Usage

Colors(ras, cols, n = NULL)

Arguments

`ras`	A `⁠Raster*⁠` or `SpatRaster` class object.
`cols`	a character vector of colours. See examples. Can also be a `data.frame`, see `terra::coltab`
`n`	A numeric scalar giving the number of colours to create. Passed to `⁠quickPlot::setColors(ras, n = n) <- ⁠`. If missing, then `n` will be `length(cols)`

Examples


cols <- colorRampPalette(c("blue", "red"))(12)
ras <- terra::rast(matrix(1:100, 10, 10))
ras <- Colors(ras, cols)
terra::plot(ras)

ras <- raster::raster(matrix(1:100, 10, 10))
ras <- Colors(ras, cols)
raster::plot(ras)
