Question

BlackTom AI · Accepted Answer

When adjusting how a code chunk behaves in Quarto, there are two main characteristics at play: whether the code is displayed and whether it is executed. 
Option: 'echo: false' — In Quarto, setting echo to false hides the actual code in the rendered output while still executing the code block. This means viewers see the results, graphs, or printed output, but not the underlying code lines themselves. This behavior is common for presentational notebooks where the emphasis is on results rather than the code. 
If we compare to other possible settings (even though they are not listed here): echo: true would display the code along with its output; eval controls whether the code actually runs at all (with eval: true executing and eval: false showing nothing from that chunk). However, since the question specifically asks for the option that both executes code and does not display it, echo: false matches that requirement precisely. 
In summary, the option provided specifies that the code will be run but kept hidden from the final display, which aligns with the described behavior of executing without showing the code.
