The example is amazing. It's so simple to do the elegant job, but I think it
requires some modification because the the size of the two dataset is

In [68]: r1.shape
Out[68]: (6080,)

In [69]: r2.shape
Out[69]: (1046,)

Maybe we need to do some trimming in the example such as:

l = min(r1.shape[0], r2.shape[0])
