Parallel Coordinates in R

Category: Visualization — Raffael Marty @ 3:25 pm

I am still playing with R to generate graphs. I have to say, after some initial frustrations, I think I start to get it. Here are some steps to generate parallel coordinate graphs in R:

Dataset < - read.table("/home/ram/foo2_200.csv", header=FALSE, sep=",") require(lattice) parallel(~Dataset,data=Dataset)

That's the very basics to generate a parallel coordinate plot. An interesting addition to this is to use a different command to generate the parallel coordinate plots:


This will generate n different parallel coordinates, one for each of the values in Dataset$V4 [where Dataset$V4 is the fourth column of our data].

Following is my last attempt. I wanted to change the axis labels. The y-axis I was sucessful in changing. For the x-axes, I was not able to change the labeling. I guess this is precisely the problem with R. Simple things are fairly simple to do, but if you want to change specific details, it gets quite messy quite quickly.
