Convert RasterStack into data.frame of colors that can be used for plotting

raster_colors-RasterStack-method.Rd

This function is used internally by plot_layer to convert a RasterStack object to a data.frame of colors for each pixel that can be used for plotting with ggplot2. Note that this function assumes that the first three bands in the RasterStack objects are the RGB values and all additional bands are ignored.

Usage

# S4 method for RasterStack
raster_colors(x)

Arguments

x

A RasterStack object

Value

A data.frame with 3 columns and length(raster_object) rows

Examples

if (FALSE) {
wi_leaf_off_layer <- get_image_layer(wi_leaf_off_url, wis_poly)
wi_leaf_off_data <- raster_colors(wi_leaf_off_layer)
}
