mkinresplot: Function to plot residuals stored in an mkin object

Description

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.

Usage

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

Value

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

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.
standardized: Should the residuals be standardized by dividing by the standard deviation given by the error model of the fit?
xlab: Label for the x axis.
ylab: Label for the y axis.
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?
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.
