compose_plot
plots images (raster brick or raster stack) and corresponding color bars according to given rectangular layout.
compose_plot(…)
Set of arguments, which are passed to compose_panel
and compose_legend
This function returns NULL
value.
Function merges to functions. The first one plots image layout and returns list of color tables. The second one plots legend (colorbars) based on returned color tables. Simplified description is:
ct <- compose_panel(...) compose_legend(ct,...)
These two functions are separated to allow use additional plotting on image panel after primary plot of raster and decorations before panel change or legend plot.
