  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

var.label

if TRUE, each variable's axis is labelled with maximum and minimum values.

ylab

label for the Y axis.

...

further graphics parameters which are passed to matplot.
