panel_decor: Add auxiliary elements to the plotting panel.

panel_decorR Documentation

Add auxiliary elements to the plotting panel.

Description

panel_decor adds over plot sequentially the followed elements: coastline, gridline, scalebar. Unlike panel_decor, function layout.grid does not add scalebar.

Usage

panel_decor(...)

Arguments

...

Passed to sequence of plotting functions:

  • panel_graticule. To distinguish the same argument names in different functions it is provided to use prefix “grid.*”, e.g., grid.col="grey40".

  • panel_coastline. To distinguish the same argument names in different functions it is provided to use prefix “coast.*”, e.g., coast.col="grey60".

  • (not applicable for layout.grid) panel_scalebar. To distinguish the same argument names in different functions it is provided to use prefix “scalebar.*”, e.g., scalebar.col="black".

Details

The sequence of elements is constant. To change order, use direct calling of panel_graticule, panel_coastline, panel_scalebar in any sequence.

Sometimes, for rasters with NA values the followed sequence may be used:

panel_coastline(col="transparent",fill="grey80")
panel_raster(a)
panel_coastline(col="grey40")

Value

panel_decor returns NULL value.
layout.grid returns NULL value.
