how to modify values using integer-based indexing

[arfriedman]

Hi all,

I am enjoying using integer-based (isel) indexing to select DataArray coordinates as it's more explicit than numpy positional indexing. However, I'm confused about how to modify individual values of a DataArray using this type of indexing.

For example, suppose I have a DataArray da with coordinate dimensions lat and lon.
I would like to do something like to set the value and the 1st latitude and 2nd longitude points to 10:
da.isel(lat=0, lon=1) = 10

However, according to the documentation, this is not recommended:

Do not try to assign values when using any of the indexing methods isel or sel:

DO NOT do this

da.isel(space=0) = 0

I'm having difficulty finding the correct approach in the documentation. Is there a recomended method?

Thanks much,
Andrew

This can be done using da[dict(lat=0, lon=1)] = 10.

Thank you!

Perhaps it would be helpful to include this recommended approach in the documentation where it instructs not to assign values using isel? I do see that there is an example of integer-based dictionary assignment in the following subsection ([87]), but to me it was not initially clear that this addresses the warning in the red box above.

@arfriedman A pull request to add that to the documeentation would be very welcome!

Will do!
