utility for developing package - searches for text in each function exported by pkg (or each .R source file in pkg/R)

Usage

pkg_functions_that_use(
  text = "stop\\(",
  pkg = "EJAM",
  ignore_comments = TRUE
)

text

something like "EJAM::" or "stop\(" or "library\(" or "***"

pkg

name of package or path to source package root folder - this

checks only the exported functions of an installed package, if pkg = some installed package as character string like "EJAM"

checks each .R source FILE NOT each actual function, if pkg = root folder of source package with subfolder called R with .R source files

ignore_comments

logical, ignore_comments is ignored and treated as if it were TRUE when pkg = some installed package

ignore_comments is used only if pkg = a folder that contains .R files

Note it will fail to ignore comments in .R files that are at the end of the line of actual code like print(1) # that prints 1

vector of names of functions or paths to .R files

Searches the body and parameter defaults of exported functions.
