Usage

## S3 method for class 'ICS'
screeplot(
  x,
  index = NULL,
  type = "barplot",
  main = deparse(substitute(x)),
  ylab = "generalized kurtosis",
  xlab = "component",
  names.arg = index,
  labels = TRUE,
  ...
)

Arguments

x	object of class ICS
index	index of the components to be plottes. If NULL all components are used.
type	"barplot" if a barplot or "lines" if a line plot is preferred.
main	main title of the plot.
ylab	y-axis label.
