shouldPrint: For use by packages that mimic/divert auto printing e.g. IRkernel and knitr

Description

Not for use by users. Exported only for use by IRkernel (Jupyter) and knitr.

Usage

shouldPrint(x)

Value

TRUE or FALSE.

Arguments

x

A data.table.

Details

Should IRkernel/Jupyter print a data.table returned invisibly by DT[,:=] ? This is a read-once function since it resets an internal flag. If you need the value more than once in your logic, store the value from the first call.
