get.full.path: Expand a file path to an absolute path

In drmjc/mjcbase: General helper functions for dealing with \R objects/data types

Description

This function has more capabilities than path.expand, in that relative paths (. and ./ and ../ and implicit ./) are also expanded, and more than normalizePath, in that files with an implicit ./ are also expanded relative to the current working dir, and files that don't currently exist can also expanded (see examples).

Usage

get.full.path(path, trailing.slash = TRUE)

Arguments

path	A character vector of paths to files or directories
trailing.slash	logical. if TRUE, and path is a directory, include a trailing “/”

Value

A character vector containing the full paths to files or directories given by “file”

Examples

## Not run: 
path.expand("~")
normalizePath("~")
get.full.path("~", trailing.slash=FALSE)
get.full.path("~", trailing.slash=TRUE)

path.expand("./")
normalizePath("./")
get.full.path("./")

path.expand("../")
normalizePath("../")
get.full.path("..")

#
# benefits over other approaches
# - file doesn't have to exist already
get.full.path("sgsdf.zip")
# [1] "/Users/marcow/src/R/mjcbase/R/sgsdf.zip"
path.expand("sgsdf.zip")
# [1] "sgsdf.zip"
normalizePath("sgsdf.zip")
# [1] "sgsdf.zip"
