S4 methods for function plot. As in the generic plot S3 `graphics' method, these methods plot Interval-valued data contained in '>IData objects.
# S4 method for IData
plot(x, y, type=c("crosses","rectangles"), append=FALSE, …)
# S4 method for IData
plot(x, casen=NULL, layout=c("vertical","horizontal"), append=FALSE, …)
