Other datasets

[scls19fr]

Hello,

you can, if you want, use one of these datasets
https://github.com/Rdatasets/python

• titanic: Survival of passengers on the Titanic
• hair_eye_color: Hair and Eye Color of Statistics Students

data are taken from R core datasets
but code is mine.

It can probably be useful for a tutorial about xarray.
It can also probably be useful to compare R and Python.

see my issue about mosaic plot pydata/xarray#779

It could also help to improve how DataArrays display.

See for example in R:

> HairEyeColor
, , Sex = Male

       Eye
Hair    Brown Blue Hazel Green
  Black    32   11    10     3
  Brown    53   50    25    15
  Red      10   10     7     7
  Blond     3   30     5     8

, , Sex = Female

       Eye
Hair    Brown Blue Hazel Green
  Black    36    9     5     2
  Brown    66   34    29    14
  Red      16    7     7     7
  Blond     4   64     5     8

and using Python/xarray

In [1]: import hair_eye_color
In [2]: hair_eye_color.data
Out[2]:
<xarray.DataArray 'Freq' (Sex: 2, Eye: 4, Hair: 4)>
array([[[32, 53, 10,  3],
        [11, 50, 10, 30],
        [10, 25,  7,  5],
        [ 3, 15,  7,  8]],

       [[36, 66, 16,  4],
        [ 9, 34,  7, 64],
        [ 5, 29,  7,  5],
        [ 2, 14,  7,  8]]])
Coordinates:
  * Sex      (Sex) <U6 'Male' 'Female'
  * Eye      (Eye) <U5 'Brown' 'Blue' 'Hazel' 'Green'
  * Hair     (Hair) <U5 'Black' 'Brown' 'Red' 'Blond'

Kind regards
