R: Create a new 'Makevars' file, by adding new variables

set_makevars {withr}

R Documentation

Create a new `Makevars` file, by adding new variables

You probably want with_makevars() instead of this function.

set_makevars(variables, old_path = file.path("~", ".R", "Makevars"),
  new_path = tempfile(), assignment = c("=", ":=", "?=", "+="))

`variables`	`[named character]` new variables and their values
`old_path`	`[character(1)]` location of existing `Makevars` file to modify.
`new_path`	`[character(1)]` location of the new `Makevars` file
`assignment`	`[character(1)]` assignment type to use.

Unlike with_makevars(), it does not activate the new Makevars file, i.e. it does not set the R_MAKEVARS_USER environment variable.
