plot.msc: Display an msc object
In CombMSC: Combined Model Selection Criteria

Description Usage Arguments Details Author(s)

Provides several options for displaying the output of TMC.

1 2	## S3 method for class 'msc' plot(x, sumfun.Index = "def", fancy = FALSE, grayscale = FALSE, draw.Grid = TRUE, ...)

`x`	An msc object, outputted by `TMC`.
`sumfun.Index`	This is the index number of the summary function you wish to plot. Available summary functions are listed in the summary.Functions component of the msc object.
`fancy`	If TRUE, will generate a 3-D plot (based on package rgl) of the results. Only works if the objects msc.List component is of length exactly 3.
`grayscale`	If true, will make the plots grayscale instead of color. Useful for printing. Only effective if `fancy` is FALSE.
`draw.Grid`	Draws a grid in the background of each Lattice plot. Only effective if `fancy` is FALSE.
`...`	Other graphical parameters.

If, as we recommend, msc.List is of length exactly 3, the plot will display as a function of 2 independent variables. This is because, although there are technically 3 independent variables (the weights of the 3 distinct MSCs,) they are related by the equation weight_1 + weight_2 + weight_3 = 1. Hence the function is defined only on the simplex joining the 3 vectors (0,0,1), (0,1,0), (1,0,0), and so may be viewed as a 2-dimensional set. Thus, in the plot, each corner represents a pure msc, and the interior of the triangle represents the various convex combinations of them in an intuitive way.

For an msc.List of length 4, the plot produces a trellis of plots by conditioning on the weight of the 4th msc. For msc.List length larger than 4, there is no default plotting method available — instead try using summary.msc.
