Usage

## S3 method for class 'dssPrincomp'
biplot(

  type = "combine",
  levels = NULL,
  draw.arrows = TRUE,
  ...,
  datasources = NULL
)

Arguments

x	an object of class dssPrincomp.
choices	length 2 vector specifying the components to plot (same as for biplot.princomp)
type	a character which represents the type of analysis to carry out. If type is set to 'combine', global column means are calculated if type is set to 'split', the column means are calculated separately for each node.
levels	a character the name of a factor. If provided, the plot will be colour coded by the levels of this factor
