find_root {rprojroot}R Documentation

Find the root of a directory hierarchy

Description

A root is defined as a directory that contains a regular file whose name matches a given pattern and which optionally contains a given text. The search for a root starts at a given directory (the working directory by default), and proceeds up the directory hierarchy.

Usage

find_root(criterion, path = ".")

Arguments

criterion

A criterion, will be coerced using as.root_criterion

path

The start directory

Details

Starting from the working directory, the find_root function searches for the root. If a root is found, the ... arguments are used to construct a path; thus, if no extra arguments are given, the root is returned. If no root is found, an error is thrown.

Value

The normalized path of the root as specified by the search criterion. Throws an error if no root is found
