resplot

An (overlayed) residuals barplot

Description

A plotting function which displays a barplot of the (standardized) residuals. The bars are colour-coded with heat colours proportional to the residual value. As default, the residuals are displayed together with the points of the fitted PCR curve.

Usage

resplot(object, overlay = TRUE, ylim = NULL, ...)

Arguments

`object`	an object of class 'pcrfit.
`overlay`	logical. If `TRUE`, the residuals are plotted on top of the fitted curve, else alone.
`ylim`	graphical ylim values for tweaking the scale and position of the barplot overlay.
`...`	any other parameters to be passed to `barplot`.

Details

If replicate data is present in the fitted curve, the residuals from all replicates i, j are summed up from the absolute values: Y_i = ∑{|\hat{\varepsilon}_{i, j}|}.

Value

A plot as described above.

Examples

## Create l5 model and plot 
## standardized residuals.
m1 <- pcrfit(reps, 1, 2, l5)
resplot(m1)

## Not run: 
## Using replicates.
m2 <- pcrfit(reps, 1, 2:5, l5)
resplot(m2)

## End(Not run)
