clustMDparcoord: Parallel coordinates plot adapted for
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 = "", ...)
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.
lty
a vector of line types, recycled as necessary for each
observation.
var.label
if TRUE, each variable's axis is labelled with maximum and
minimum values.
xlab
label for the X axis.
ylab
label for the Y axis.
...
further graphics parameters which are passed to matplot
.
Value
A parallel coordinates plot is drawn with one line for each cluster.References
