Functions in path

Parses files in given path. It searches for functions and loads them. Is safe for use with scripts as it doesn't source the whole file, just functions. There are no side-effects to sourcing .R files.

find_functions(path, envir = .GlobalEnv, recursive = TRUE)

Arguments

path	Character, path to folder
envir	Environment to source loaded functions into
recursive	Logical, whether to search files recursively

Value

A tibble with character columns indicating path to source files and names of functions defined in them. Path elements are split into columns with `Level` prefix, name of source file is in `Source` column, name of function is in `Function` column.

Examples

# \donttest{
path <- file.path(tempdir(), "find_functions_example")
dir.create(path, showWarnings = FALSE)
code <- "
add <- function(x, y) {
  x + y
}
add_one = function(x) {
  add(x, 1)
}
assign('add_two', function(x) {
  add(x, 2)
})
"
write(code, file.path(path, "code.R"))
find_functions(path)
