plotshapes function

Plot configurations

Plots configurations. Either one or two groups of observations can be plotted on the same scale.

plotshapes(A, B = 0, joinline = c(1, 1),orthproj=c(1,2),color=1,symbol=1)

Arguments

• A: k x m x n array, or k x m matrix for first group
• B: k x m x n array, or k x m matrix for 2nd group (can be missing)
• joinline: A vector stating which landmarks are joined up by lines, e.g. joinline=c(1:n,1) will start at landmark 1, join to 2, ..., join to n, then re-join to landmark 1.
• orthproj: A vector stating which two orthogonal projections will be used. For example, for m=3 dimensional data: X-Y projection given by c(1,2) (default), X-Z projection given by c(1,3), Y-Z projection given by c(2,3).
• color: Colours for points. Can be a vector, e.g. 1:k gives each landmark a different colour for the specimens
• symbol: Plotting symbols. Can be a vector, e.g. 1:k gives each landmark a different symbol for the specimens

Returns

Just graphical output
