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 {.

  • 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.





An R object. Functions and calls are walked recursively.
