build_bulk_file: File-backed raster file.
In AustralianAntarcticDivision/aceecostats: Ecosystem status and trends

Description Usage Arguments Details Value

Build a file-backed raster from a collection of file names and dates.

1	build_bulk_file(files, filename, read_i_raster = NULL, layer_prefix = "lyr")

`files`	data frame with 'fullname' and 'date'
`filename`	database of files, see Details
`read_i_raster`	function to read the i-th file
`layer_prefix`	optional prefix to give each layer, pre-pended to the date

The files collection must have columns 'fullname' with the path to the file, and 'date' with a valid date or date-time. The function 'read_i_raster' takes an integer and the files collection and returns the raster read from the i-th row. The date is set on the object after this function returns, to ensure it matches the database of files, and also so that the raster function can be used as a fallback.
