here (version 1.0.1)

here: Find your files

Description

here() uses a reasonable heuristics to find your project's files, based on the current working directory at the time when the package is loaded. Use it as a drop-in replacement for file.path(), it will always locate the files relative to your project root.

Usage

here(...)

Arguments

...

[character] Path components below the project root, can be empty. Each argument should be a string containing one or more path components separated by a forward slash "/".

Project root

The project root is established with a call to here::i_am(). Although not recommended, it can be changed by calling here::i_am() again.

In the absence of such a call (e.g. for a new project), starting with the current working directory during package load time, the directory hierarchy is walked upwards until a directory with at least one of the following conditions is found:

• contains a file .here

• contains a file matching [.]Rproj$ with contents matching ^Version: in the first line

• contains a file DESCRIPTION with contents matching ^Package:

• contains a file remake.yml

• contains a file .projectile

• contains a directory .git

• contains a file .git with contents matching ^gitdir:

• contains a directory .svn

In either case, here() appends its arguments as path components to the root directory.

Details

This package is intended for interactive use only. Use rprojroot::has_file() or the other functions in the rprojroot package for more control, or for package development.

If here() raises an error or otherwise behaves unexpectedly, you may have attached plyr or another package after here. Correct this using the conflicted package, or use here::here("data", "df.rda").

Examples

# NOT RUN {

# NOT RUN {
here("some", "path", "below", "your", "project", "root.txt")
