plotclean

Plot multiple growth curves to identify outliers

Description

A version of mplot to plot growth curves and identify outliers. When outliers are clicked on, and if id is specified, the corresponding growth curve is highlighted. If id is not specified the selected point is highlighted. Use right-click to exit.

Usage

plotclean(
  x,
  y,
  id = NULL,
  data = parent.frame(),
  n = length(x),
  par.out = list(pch = 20),
  ...
)

Arguments

`x`	vector of x coordinates.
`y`	vector of y coordinates.
`id`	factor of subject levels indexing each growth curve.
`data`	optional dataframe containing `x`, `y` and `id`.
`n`	maximum number of points to be identified.
`par.out`	list of optional graphical parameters to control appearance of selected outlying points and lines.
`...`	Further graphical parameters (see `par`) may also be supplied as arguments for lines and points, particularly line type, lty, line width, lwd and color, col.

Value

plotclean returns either a vector rows (if data is not specified) or a list:

`rows`	a vector of row numbers corresponding to the selected points.
`data`	a subset of `data` consisting of rows `rows`, and columns `id`, `x` and `y`.
