Add a colour bar for a mesh — add_colour

Add a colour bar that corresponds to the colours in a given colourized mesh to the current rgl device

Usage

add_colour_bar(
  mesh,
  title = "",
  lpos = 0.97,
  rpos = 0.99,
  bpos = NULL,
  tpos = NULL,
  bpos2 = NULL,
  tpos2 = NULL,
  nudge_title_y = 0.5,
  nudge_title_x = 0.82,
  vertical = TRUE,
  ...
)

Arguments

mesh: A obj_mesh object created with colour_mesh
title: The label to give the colour bar
lpos: the position for the left edge of the colour bar in fraction of the plot area, defaults to .97
rpos: the position for the right edge of the colour bar in fraction of the plot area, defaults to .99
bpos: the position for the bottom edge of the colour bar in fraction of the plot area. In the symmetric case this is for the negative scale. Defaults to .25 for non-symmetric and .05 for symmetric.
tpos: the position for the top edge of the colour bar in fraction of the plot area. In the symmetric case this is for the negative scale. Defaults to .75 for non-symmetric and .45 for symmetric.
bpos2: the position for the bottom edge of the colour bar in fraction of the plot area. Only used in the symmetic case for the positive scale, defaults to .55
tpos2: the position for the top edge of the colour bar in fraction of the plot area. Only used in the symmetric case for the positive scale, defaults to .95
nudge_title_y: Offset text from the bottom of a colour bar by y, units are in proportions of the colour bar length
nudge_title_x: Offset text from the bottom of a colour bar by x, units are in proportions of the colour bar width
vertical: whether to use a vertical or horizontal layout for the colour bar
...: extra parameters to pass to plotrix::color.legend and text
