In ahb108/sparch: Assorted methods to supplement core spatial packages in R

Description

Handle the positioning and labelling of a (spatstat) colour ramp more easily.

Usage

ribbonplot(
  x,
  y,
  xprop,
  yprop,
  zlim,
  cm = NULL,
  steps = 4,
  sigdigits = NULL,
  rounding = NULL,
  vertical = TRUE,
  ...
)

Arguments

x	y-axis location of the colourramp lower-left corner.
xprop	proportion of plot width to be allocated to the colour ramp width
yprop	proportion of plot height to be allocated to the colour ramp height
zlim	minimum and maximum values for the colour ramp
cm	object of class 'colourmap' to plot (or default spatstat colour ramp if left null)
steps	how many numerical steps to label in the ramp legend
sigdigits	how to round the digits in the labels
rounding	to how many decimal places should the labels be rounded
vertical	whether the ramp is places as a vertical or horizontal ribbon

Value

an image ribbon added to an existing plot.

Examples

exampledensitymap <- density(cells, 0.05)
plot(exampledensitymap, ribbon=FALSE)
ribbonplot(x=0.1, y=0.1, xprop=0.03, yprop=0.2, zlim=c(min(exampledensitymap),max(exampledensitymap)), cex.axis=0.6, col.axis="white", col.ticks="white", las=2)
