Helper for setting Raster or SpatRaster colors

Source: R/plotting.R

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

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

# \donttest{
cols <- colorRampPalette(c("blue", "red"))(12)
ras <- terra::rast(matrix(1:100, 10, 10))
ras <- Colors(ras, cols)
#> not enough colours, interpolating
terra::plot(ras)


ras <- raster::raster(matrix(1:100, 10, 10))
ras <- Colors(ras, cols)
raster::plot(ras)
#> Warning: CRS is NA. Assuming it is longitude/latitude
