step_run_code: Step: Run arbitrary R code

Description

Captures the expression and executes it when running the step. An optional preparatory expression can be provided that is executed during preparation. If the top-level expression is a qualified function call (of the format package::fun()), the package is installed during preparation.

Usage

step_run_code(call = NULL, prepare_call = NULL)

Arguments

call

[call] An arbitrary R expression executed during the stage to which this step is added. The default is useful if you only pass prepare_call.

prepare_call
