Description

Plot vector classified cube

Usage

## S3 method for class 'class_vector_cube'
plot(
  x,
  ...,
  tile = x[["tile"]][[1L]],
  legend = NULL,
  seg_color = "black",
  line_width = 0.5,
  palette = "Spectral",
  scale = 1,
  legend_position = "outside"
)

Arguments

x	Object of class "segments".
...	Further specifications for plot.
tile	Tile to be plotted.
legend	Named vector that associates labels to colors.
seg_color	Segment color.
line_width	Segment line width.
palette	Alternative RColorBrewer palette
scale	Scale to plot map (0.4 to 1.0)
legend_position	Where to place the legend (default = "outside")

Value
