Primitive Print

Prints an array value to the console during execution and returns the input unchanged. This is useful for debugging JIT-compiled code. Bare R inputs print at their category's default data type.

Usage

prim_print(x)

Arguments

x

(arrayish)
One input. Can be any data type. An R value materializes at its default data type.

Value

(arrayish)
Returns the input unchanged.
