I want to reduce the number of rows printed by default for a DataFrame in Jupyter. How do I do that?

I have no idea how Jupyter handles printing, but FWIW from the DataFrames side we use `displaysize` and print as many rows as can fit on screen.

So the below will print only 6 rows now!

```julia
Base.displaysize() = (6, 80)

```

I put out a Stackoverflow community wiki

You shouldn’t overwrite the Base method like that… You can set e.g. ` ENV["LINES"] = 10` instead or use the `do` form of `displaysize` (see the docs) to apply it to a block. If this doesn’t work then the IJulia needs a way to set the displaysize of the io object it uses.
