bug: replace errors, but substitute works

[KronosTheLate]

What happened?

This errors:

t = ibis.memtable({"c1": [1, 2]})
t["c1"].replace

While this runs:

t = ibis.memtable({"c1": [1, 2]})
t["c1"].substitute

If this is intentional, the docstrings for replace and substitute sure as frick dont seem to mention it. For substitute, we have:

This is similar to the pandas replace method.

While replace does not even mention substitute.

Is this expected? Is there actually a difference between the two functions, other than the added keyword argument for substitute?

What version of ibis are you using?

ibis-framework 10.5.0

What backend(s) are you using, if any?

The error is intentional. replace is only available on string columns:

In [3]: from ibis.interactive import *

In [4]: t = ibis.memtable({"c1": [1, 2]})

In [5]: t["c1"].replace

In the future, it will help if you show a traceback of the error. The particular failure mode matters quite a lot.
