construct_reprex — construct_reprex • constructive

construct_reprex() constructs all objects of the local environment, or a caller environment n steps above. If n > 0 the function call is also included in a comment.

Usage

construct_reprex(n = 0, ...)

Arguments

n: The number of steps to go up on the call stack
...: Forwarded to construct_multi()

Value

Returns return NULL invisibly, called for side-effects.

Details

construct_reprex() doesn't call the {reprex} package but it shares the purpose of making it easier to reproduce an output, hence the name. If you want to it to look more like a reprex::reprex consider options(constructive_print_mode = "reprex"). See ?constructive_print_mode for more.

construct_reprex() wraps construct_multi() and is thus able to construct unevaluated arguments using delayedAssign(). This means we can construct reprexes for functions that use Non Standard Evaluation.

A useful trick is to use construct_reprex() with options(error = recover) to be able to reproduce an error.

construct_reprex() might fail to reproduce the output of functions that refer to environments other than their caller environment. We believe these are very rare and that the simplicity is worth the rounded corners, but if you encounter these limitations please do open a ticket on our issue tracker at https://github.com/cynkra/constructive/ and we might expand the feature.
