Function to plot residuals stored in an mkin object

This function plots the residuals for the specified subset of the observed variables from an mkinfit object. A combined plot of the fitted model and the residuals can be obtained using plot.mkinfit using the argument show_residuals = TRUE.

mkinresplot(object,
    obs_vars = names(object$mkinmod$map),
    xlim = c(0, 1.1 * max(object$data$time)),
    xlab = "Time", ylab = "Residual",
    maxabs = "auto", legend = TRUE, lpos = "topright",
    col_obs = "auto", pch_obs = "auto",
    frame = TRUE,
    ...)

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. Defaults to "Time [days]".
ylab

Label for the y axis. Defaults to "Residual [% of applied radioactivity]".
maxabs

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

Should a legend be plotted? Defaults to "TRUE".
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.
frame

Should a frame be drawn around the plots?
...

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

model <- mkinmod(parent = mkinsub("SFO", "m1"), m1 = mkinsub("SFO"))
#> Successfully compiled differential equation model from auto-generated C code.
fit <- mkinfit(model, FOCUS_2006_D, quiet = TRUE)
#> Warning: Observations with value of zero were removed from the data
mkinresplot(fit, "m1")
