plot: Plot method for the `trigrid`, `hexagrid` or `facelayer` classes

Description

This function will invoke the plot method of the SpatialPolygons class.

The function passes arguments to the plot method of the SpatialPolygons class. In case a heatmap is plotted and the plotting device gets resized, some misalignments can happen. If you want to use a differently sized window, use x11 to set the height and width before running the function.

Usage

plot
# S4 method for trigrid,ANY
plot(x, projargs = NULL, ...)
# S4 method for facelayer,ANY
plot(
  x,
  projargs = NULL,
  col = "heat",
  border = NA,
  alpha = NULL,
  frame = FALSE,
  legend = TRUE,
  breaks = NULL,
  inclusive = TRUE,
  discrete = FALSE,
  ...
)

Arguments

(trigrid, hexagrid or facelayer) The object to be plotted.

projargs

(character or CRS) A projection string for the transformation fo coordinates.

...

Arguments passed to the plot function.

col

(character) Colors passed to a colorRamp in case of the facelayer contains logical values, a single value is required (defaults to "red").

border

(character) Specifyies the color of the borders of the cells.

alpha

(character) Two digits for the fill colors, in hexadecimal value between 0 and 255.

frame

(logical) If TRUE the grid boundaries will be drawn with black.

legend

(logical): Should the legend be plotted?

breaks

(numeric) The number of breakpoints between the plotted levels. The argument is passed to the cut function.

inclusive

(logical): If there are values beyond the limits of breaks, should these be represented in the plot (TRUE) or left out completely FALSE?

discrete

(logical): Do the heatmaps symbolize a discrete or a continuous variable? This argument only affects the legend of the heatmap.

Value

The function has no return value.

Format

An object of class standardGeneric of length 1.
