Pretty print of R Jupyter Notebook inside a function

Question

When calling head(...) in a cell in jupyter notebook, we get a nice table with the data

However if I want to do the same in a function, nothing is shown, so I have to use print(head(...)) but the result is less pretty as you can see

Is there a way to get the same type of output as the first image but in a function ?

Answer 1

Jupyter display functions for IRkernel are provided by the IRdisplay package, which gets installed together with IRkernel (by default). Just use:

IRdisplay::display(CO2)

Or load the library into the namespace first:

library(IRdisplay)
data("CO2")
a <- function() {
    display(head(CO2))
}
a()

Which works as intended:
