zap_srcref: Zap source references

In hadley/rlang: Functions for Base Types and Core R and 'Tidyverse' Features

Zap source references

Description

There are a number of situations where R creates source references:

• Reading R code from a file with source() and parse() might save source references inside calls to function and ⁠{⁠.

• sys.call() includes a source reference if possible.

• Creating a closure stores the source reference from the call to function, if any.

These source references take up space and might cause a number of issues. zap_srcref() recursively walks through expressions and functions to remove all source references.

Usage

zap_srcref(x)

Arguments

x	An R object. Functions and calls are walked recursively.
