Called by the plot_scatter module in the example app and samples values from a raster along with either the x or y coordinates of the points sampled
plot_scatter(raster, sample, axis, name, logger = NULL)Arguments
- raster
SpatRaster. Raster to be sampled
- sample
numeric. Number of points to sample
- axis
character. Which axis coordinates of the raster to return
- name
character. The name of the raster variable
- logger
Stores all notification messages to be displayed in the Log Window. Insert the logger reactive list here for running in shiny, otherwise leave the default NULL
Value
a function that generates a scatterplot
