plot_iso: Visualize a single isoband

In isoband: Generate Isolines and Isobands from Regularly Spaced Elevation Grids

Visualize a single isoband

Description

This function visualizes a single isoband calculated from a matrix. It is mainly useful for debugging and visualizing the isobanding algorithm. See isobands() for more examples.

Usage

plot_iso(
  m,
  vlo,
  vhi,
  fill_lo = "gray95",
  fill_mid = "gray50",
  fill_hi = "black",
  fill_band = "cornsilk",
  col_lo = "black",
  col_hi = "black",
  newpage = TRUE
)

Arguments

m	input matrix
vlo	lower cutoff for isobanding
vhi	higher cutoff for isobanding
fill_lo	fill color for points below the lower cutoff
fill_mid	fill color for points between the two cutoffs
fill_hi	fill color for points above the higher cutoff
fill_band	fill color for the isoband
col_lo	line color for lower cutoff
col_hi	line color for higher cutoff
newpage	boolean, indicating whether grid.newpage() should be called or not

Examples

m <- matrix(c(0, 0, 0, 0, 0, 0,
              0, 2, 2, 2, 2, 0,
              0, 2, 0, 0, 2, 0,
              0, 2, 0, 0, 2, 0,
              0, 2, 2, 2, 2, 0,
              0, 0, 0, 0, 0, 0), 6, 6, byrow = TRUE)

plot_iso(m, 0.5, 1.5)
