dot: Create paths that are safe from changing working directory.

In lemon: Freshing Up your 'ggplot2' Plots

Create paths that are safe from changing working directory.

Description

The .dot functions creates functions that allows relative-like specification of paths, but are safe from changing working directory.

Usage

.dot(x, root = getwd(), mustExist = FALSE, relative = FALSE, create = TRUE)

.dot2(names, quiet = FALSE, ...)

Arguments

x	File path that is appended to BASEDIR.
root	Root of your working directory, from which x is relative too.
mustExist	Logical value; if TRUE and the resulting path does not exist, it raises an error.
relative	For .dot, sets default for the returned function. For the returned function, when TRUE, the function returns a path relative to root.
create	Logical values, creates the target directory when TRUE (default).
names	Character vector of names
quiet	Logical value, suppresses output to stdout() when TRUE.
...	Arguments passed on to .dot.

Value

A function that returns file paths constructed from root, x, and ....

Side effect: It creates the directory.

Examples

.data <- .dot('data', create=FALSE)
.data('input.txt')
.data(c('a.txt','b.txt'))

.dot2(c('rawdata','results'), create=FALSE)
.rawdata('rawfile.csv')
.results('myresults.txt')
