Parallel Coordinate Plot

Description

Constructs a parallel coordinate plot for a data set with classes

Usage

parallelplot(x, name = "", comb = 0, class = 0, obs = rep(0, 0), 
col = 2, lty = 1, ...)

Arguments

x matrix of numerical values with classes in last column
name name of data set as will appear in the graph title
comb if comb=0, all distinct combinations of columns are graphed, else should be an integer that represents the number of one of the possible combinations for the columns of this matrix.
class value representing the class number to which the plot should be limited
obs list of one or more row numbers that are to be highlighted in the plot
col value that provides a choice of color for the plot if limited to one class
lty value that provides a choice of line width for the plot if limited to one class
... additional arguments for the matplot function

Details

This plot is not recommended for a large number of features (say more than 50)

Value

A parallel coordinate plot of the data is produced
