resplot: An (overlayed) residuals barplot

In qpcR: Modelling and Analysis of Real-Time PCR Data

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)
