Plot the fit for standards and the samples

Description

Produces a plot that includes points for standards, proposed fit, removed outliers, bounds for "flat" portions of the curve, and values for samples and for the background.

Usage

plotFit(
  std,
  xvar,
  yvar,
  fitpar = NULL,
  FUNmod = NULL,
  FUNinv = NULL,
  iout = NULL,
  bg = NULL,
  vsmp = NULL,
  smpflag = NULL,
  trimval = NULL,
  trimtype = NULL,
  extrapolate.low = FALSE,
  extrapolate.up = FALSE,
  ylim = NULL,
  tcklab = NULL,
  stdcol = c("firebrick3", "darkslategray"),
  rugcol = c("cadetblue", "purple", "firebrick2"),
  ...
)

Arguments

`std`	matrix or data frame with standards for fitting.
`xvar, yvar`	character strings for the variables used to fit a standard curve. If `NULL`, first two columns are assumed to be `x` and `y` variables.
`fitpar`	values of function parameters.
`FUNmod`	model function.
`FUNinv`	model inverse function.
`iout`	indices of removed standard points.
`bg`	background values.
`vsmp`	sample values.
`smpflag`	character vector, flags for each sample.
`trimval`	for final results, the values at which the samples are trimmed.
`trimtype`	integer vector of length two indicating if the values are trimmed at the extremum (lower and upper).
`extrapolate.low`	if `TRUE`, sample values beyond lower bounds will be processed by extrapolation of the standard curve (not recommended). Takes precedence over `trim.flat` value.
`extrapolate.up`	if `TRUE`, sample values beyond upper bounds will be processed by extrapolation of the standard curve (not recommended). Takes precedence over `trim.flat` value.
`ylim`	limits of the y-axis.
`tcklab`	tick labels for x-axis.
`stdcol`	vector of two colors for the standard points and the fit on the plot.
`rugcol`	vector of three colors for the rugplot, which indicates sample values (inside the bounds, between the bounds and extrema, and beyond extrema).
`...`	further graphical parameters.
