outputter: Generate a versioned file name in a subdirectory.

In terminological/ggrrr: Addressing Annoyances and Irritations

Generate a versioned file name in a subdirectory.

Description

This function generates a function that resolves a file path fragment to a specific file location, accounting for a versioning strategy involving the current date. The defaults create a naming strategy that places an file in the "output" sub-directory of the current project with a filename suffix including the date.

Usage

outputter(
  directory = .here("output"),
  ...,
  datedFile = !datedSubdirectory,
  datedSubdirectory = FALSE
)

Arguments

directory	the root of the output
...	not used must be empty
datedFile	do you want the filename to have the date appended?
datedSubdirectory	do you want the files to be placed in a dated subdirectory?

Value

a function that takes a filename and boolean delete parameter. When called with a filename component this function will return the absolute path of a file which is versioned with date. If the file exists and delete=TRUE it is deleted. (allowing for libraries that refuse to overwrite existing files)

Examples

out = outputter("~/output",datedSubdirectory=TRUE)
out("file.png")
