BUG: Panel indexing with partial setting

[jreback]

xref #10360 / #10838

takes care of full slices, e.g. p.iloc[0,0,:] = [1,2,3], but the following is still failing
(whether mixed blocks or not)

In [8]: axes = dict(items = pd.MultiIndex.from_tuples([('A','a'), ('B','b')]), major_axis = pd.MultiIndex.from_tuples([('A',1),('A',2)]), minor_axis=pd.MultiIndex.from_product([['X'],range(3)]))

In [9]: p = Panel(0., **axes)


In [11]: p
Out[11]: 
<class 'pandas.core.panel.Panel'>
Dimensions: 2 (items) x 2 (major_axis) x 3 (minor_axis)
Items axis: (A, a) to (B, b)
Major_axis axis: (A, 1) to (A, 2)
Minor_axis axis: (X, 0) to (X, 2)

In [13]: p.iloc[0,0,1:3]
Out[13]: 
X  1    0
   2    0
Name: (A, 1), dtype: float64

In [14]: p.iloc[0,0,1:3] = [1,2]
IndexError: tuple index out of range

cc @seth-p

what would be really helpful is some more comprehensive testing to find the edge cases with panel (I added some but things take different paths so need to hit them all)

[seth-p]

The example in #10360 (comment) is still broken as of Pandas 0.18.0.

[jreback]

it's still an open issue

[jreback]

you might find xarray more convenient for representing nd data FYI

[seth-p]

I looked briefly at xarray, and I like it, but I'm not ready to abandon Panels quite yet...

closing as Panels are deprecated
