Plot Baseline Versus Post-Treatment Binding Potentials

Description

Inspired by the Lassen plot (Cunningham et al., 2010) this is a straightforward graphical summary of pre-treatment versus post-treatment binding potentials for a single subject across multiple brain regions.

Usage

plotBindingPotential(
  base,
  drug,
  lty45 = 2,
  lty = 1,
  lwd45 = 2,
  lwd = 3,
  col45 = "darkgrey",
  col = "orange",
  pch = 1,
  cex = 1,
  xlim = range(0, base, 0.5),
  ylim = range(0, drug, 0.5),
  xlab = expression(BP[ND]^{
     Base
 }),
  ylab = expression(BP[ND]^{
     Drug
 }),
  ...
)

Arguments

base	is the vector of baseline binding potentials across brain regions.
drug	is the vector of post-treatment binding potentials across brain regions.
lty45	is the line type for the 45-degree line.
lty	is the line type for the estimated regression line.
lwd45	is the line width for the 45-degree line.
lwd	is the line width for the estimated regression line.
col45	is the color for the 45-degree line.
col	is the color for the estimated regression line.
pch	is the plotting character symbol.
cex	is the size of the plotting symbol.
xlim	is the range of values on the x-axis.
ylim	is the range of values on the y-axis.
xlab	is the label on the x-axis.
ylab	is the label on the y-axis.
...	additional arguments to be passed to the plot function.
