A parallel plot is one of the few types of coordinate plots that show any number of variables in one plot. However, the relationships between variables might be evident only in the following circumstances:
– when the variables are side by side
– if you assign a color to a level of a variable to track groups
– if you select lines to track groups
# You need the MASS library
# Let's use the Iris dataset as an example
# Vector color
# Make the graph !
parcoord(iris[,c(1:4)] , col= my_colors )
