Constructs Path Functions Similar to 'this.path()'

Description

make_fix_funs() accepts a pathname and constructs a set of path-related functions, similar to this.path() and associated.

Usage

make_fix_funs(file, delayed = FALSE, local = FALSE, n = 0,
              envir = parent.frame(n + 1),
              matchThisEnv = getOption("topLevelEnvironment"),
              srcfile = if (n) sys.parent(n) else 0)

## alias for 'make_fix_funs'
path.functions(file, delayed = FALSE, local = FALSE, n = 0,
               envir = parent.frame(n + 1),
               matchThisEnv = getOption("topLevelEnvironment"),
               srcfile = if (n) sys.parent(n) else 0)

Arguments

`file`	a character string giving the pathname of the file or URL.
`delayed`	`TRUE` or `FALSE`; should the \codelink2base:normalizePathnormalization of `file` be delayed?
`local`, `n`, `envir`, `matchThisEnv`, `srcfile`	See `?this.path()`.

Value

An environment with at least the following bindings:

`this.path`	Function with formals `(original = FALSE, contents = FALSE)` which returns the \codelink2base:normalizePathnormalized file path, the original file path, or the contents of the file.
`this.dir`	Function with no formals which returns the directory of the \codelink2base:normalizePathnormalized file path.
`here`, `ici`	Function with formals `(..., .. = 0)` which constructs file paths, starting with the file's directory.
`this.proj`	Function with formals `(..., .. = 0)` which constructs file paths, starting with the project root.
`rel2here`, `rel2proj`	Functions with formals `(path)` which turn absolute paths into relative paths, against the file's directory / / project root.
`LINENO`	Function with no formals which returns the line number of the executing expression in `file`.
