In dprep: Data Pre-Processing and Visualization Functions for Classification

Description

This function creates and displays a surveyplot of a dataset for a classification matrix

Usage

surveyplot(datos, dataname = "", orderon = 0, class = 0, 
obs = rep(0, 0), lwd = 1)

Arguments

datos	A matrix of values for supervised classification
dataname	dataname Name of data set to appear in plot title
orderon	orderon Column number by which to order the dataset
class	class Class for which to limit plotting
obs	obs List of observations to be highlighted
lwd	lwd Value to control width of the line
