Identify all functions that are called by the specified function, and all functions called by them, etc

Recursively walk downwards through function calls. Two options to reduce traversal of functions that may not be of interest (e.g., "validate_.*" functions): pattern_ignore will completely ignore functions matching a

Usage

find_recursive_dependencies(
  package_name,
  fun,
  pattern_ignore = NULL,
  pattern_dont_recurse = NULL
)

Arguments

package_name

Name of pattern. Character vector, length 1

fun

Name of function. Character vector, length 1

pattern_ignore

NULL or character vector of regex patterns. If present, recursive_deps will ignore any functions that match the pattern(s) character vector. Can take multiple patterns.

pattern_dont_recurse

NULL or character vector of regex patterns. If present, recursive_deps will list functions that match the pattern(s), but will not recurse into those functions.. Can take multiple patterns.

Value

character vector
