set_library_default_posR Documentation

Modify default attach position for base::library()

Description

This function is documented but not exported. Reach in with envir:::set_library_default_pos() to use it.

Usage

set_library_default_pos(..., after = NULL, before = NULL, value = NULL)

Arguments

...

Ignored. Arguments must be named

after, before

string; the name of the environment on the search path that library() calls should by default attach after or before.

value

The value (or quoted expression) the new argument should be.

Details

This is primarily a way to "pin" a particular environment on the search path. For example, say you have a "project_utils" environment where you've defined a variety of useful functions. To prevent future library() calls from masking any objects in your attached "project_utils" environment, you can modify the default pos argument to library.

attach_source("project_utils.R", name = "project_utils)
set_library_default_pos(after = "project_utils")
library(foo) # now foo will attach after the "project_utils" environment

Value

The original default value of pos, invisibly
