mkinerrplot: Function to plot squared residuals and the error model for an mkin object

Description

This function plots the squared residuals for the specified subset of the observed variables from an mkinfit object. In addition, one or more dashed line(s) show the fitted error model. A combined plot of the fitted model and this error model plot can be obtained with plot.mkinfit using the argument show_errplot = TRUE.

Usage

mkinerrplot(object,
    obs_vars = names(object$mkinmod$map),
    xlim = c(0, 1.1 * max(object$data$predicted)),
    xlab = "Predicted", ylab = "Squared residual",
    maxy = "auto", legend= TRUE, lpos = "topright",
    col_obs = "auto", pch_obs = "auto",
    ...)

Arguments

object

A fit represented in an mkinfit object.

obs_vars

A character vector of names of the observed variables for which residuals should be plotted. Defaults to all observed variables in the model

xlim

plot range in x direction.

xlab

Label for the x axis.

ylab

Label for the y axis.

maxy

Maximum value of the residuals. This is used for the scaling of the y axis and defaults to "auto".

legend

Should a legend be plotted?

lpos

Where should the legend be placed? Default is "topright". Will be passed on to legend.

col_obs

Colors for the observed variables.

pch_obs

Symbols to be used for the observed variables.

…

further arguments passed to plot.

Value

Nothing is returned by this function, as it is called for its side effect, namely to produce a plot.

Examples

# NOT RUN {
model <- mkinmod(parent = mkinsub("SFO", "m1"), m1 = mkinsub("SFO"))
fit <- mkinfit(model, FOCUS_2006_D, error_model = "tc", quiet = TRUE)
mkinerrplot(fit)
# }
