Issue with andrewsplot function

[tomjcamp]

Using the code example :

using RDatasets, StatsPlots
  iris = dataset("datasets", "iris");
  @df iris andrewsplot(:Species, cols(1:4))

results in the following error:

ERROR: Expects 200 elements in each col of y, found 50.

What might be causing this?
