Problems with dataset transform function

I was trying to do the examples in the Holoviews webiste ( ).

Just created a dataset using
ds = hv.Dataset(np.linspace(0, np.pi), ‘x’)

And was trying to insert the transformed :

expr = np.sin(hv.dim(‘x’)*10+5)

into the dataset

transformed = ds.transform(y=expr)

But it doesn´t work

AttributeError: ‘Dataset’ object has no attribute ‘transform’

I believe there is more problems with the functions given as examples in the User Guide
Transforming Elements.

I´ve tried to apply the function

quantile_expr = hv.dim(‘air’).quantile(0.95, dim=‘time’)

in the air _temperature example and did´t work too

AttributeError: ‘dim’ object has no attribute ‘quantile’

You need HoloViews 1.13.1 (sorry the docs really need versioning).
