Description

Produces a parallel coordinates plot as parcoord in the MASS library with some minor adjustments.

Usage

clustMDparcoord(
  x,
  col = 1,
  xlabels = NULL,
  lty = 1,
  var.label = FALSE,
  xlab = "",
  ylab = "",
  ...
)

Value

A parallel coordinates plot is drawn with one line for each cluster.

Arguments

x

a matrix or data frame who columns represent variables. Missing values are allowed.

col

a vector of colours, recycled as necessary for each observation.

xlabels

a character vector of variable names for the x axis.
