averagePlot: Function to create average Plots

Description Usage Arguments Details Note Author(s) References See Also Examples

Description

averagePlot creates all x-y plots of averages by size out of an object of class gageRR.
Therfore the averages of the multiple readings by each operator on each part are plotted with the reference
value or overall part averages as the index.

Usage

1
 averagePlot(x, main, xlab, ylab, col, ask=TRUE, single=FALSE, ...)

Arguments

x

needs to be an object of class gageRR.

main

a main title for the plot

xlab

a label for the x axis

ylab

a label for the y axis

col

plotting color

ask

a logical value. If ‘TRUE’ (default) the user is asked for input, before a new figure is drawn.

single

a logical value.If ‘TRUE’ a new graphic device will be opened for each plot.
By default single is set to ‘FALSE’. For further information see details.

...

arguments to be passed to methods, such as graphical parameters (see par).

Details

averagePlot will split the screen into maximal 3x2 subscreens in which plots will be plotted.
If the six subscreens are not enough the function will (by default) ask the user before plotting
the next few plots. If ask is set to ‘FALSE’ the function will open as many graphic
devices as necessary to show all plots.
There are two possible ways to avoid the described internal routine of splitting the screen:
