plotD function

Plots heatmap for scaling coefficients obtained when generating PV-set for PCR or PLS

plotD(
  Xpv,
  colmap = colorRampPalette(c("blue", "white", "red"))(256),
  lim = c(-2, 4),
  xlab = "Components",
  ylab = "Segments",
  ...
)

Arguments

• Xpv: PV-set generated by pcvpcr() or pcvpls().
• colmap: colormap - any with 256 colors.
• lim: limits for color map (smallest/largest expected value), centered around 1.
• xlab: label for x-axis
• ylab: label for y-axis
• ...: any other parameters for method image

Returns

No return value, just creates a plot.
