scatter plot of first n principal components

4 views (last 30 days)
Hello, I know how to plot a scatter plot of the first 2 principal components. Can someone tell me how to expand the scatter plot to n dimensional data. Can we use gplotmatrix to achieve this?

First, you need to buy an n-dimensional monitor. They are rare, and quite expensive, for any value of n greater than 2. As well, mine is always breaking down. It is in for service right now, where they tell me the parts should arrive any day via teleport from Starfleet command. But you know how unreliable that can be.
Seriously, plotting data in a high number of dimensions is essentially impossible to do well. At best, you can try things like Chernoff faces, but they never seem to be useful.

Well, for n greater than 3, you probably also need some surgery to your eyes to be able to see these extra dimensions.
