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)
