This is mostly just a wrapper around filename from the raster package, except that
instead of returning an empty string for a RasterStack object, it will return a vector of
length >1 for RasterStack.
Filenames(obj, allowMultiple = TRUE, returnList = FALSE)
# S4 method for class 'ANY'
Filenames(obj, allowMultiple = TRUE, returnList = FALSE)
# S4 method for class 'environment'
Filenames(obj, allowMultiple = TRUE, returnList = FALSE)
# S4 method for class 'list'
Filenames(obj, allowMultiple = TRUE, returnList = FALSE)
# S4 method for class 'data.table'
Filenames(obj, allowMultiple = TRUE, returnList = FALSE)
# S4 method for class 'Path'
Filenames(obj, allowMultiple = TRUE, returnList = FALSE)A Raster* object (i.e., RasterLayer, RasterStack, RasterBrick)
Logical. If TRUE, the default, then all relevant
filenames will be returned, i.e., in cases such as .grd where multiple files
are required. If FALSE, then only the first file will be returned,
e.g., filename.grd, in the case of default Raster format in R.
Default FALSE. If FALSE, then return format will be a
character vector. When TRUE, list or environment objects will return a list
of character strings or vectors. When returned as a character vector, then
the names of objects with >1 filename associated with them will be given a numeric
suffix, which means the name in the returned vector does not match the object in
the list or environment. When returned as a list, their names are preserved.
A character vector of filenames that are part of the objects passed to obj.
This returns NULL is the object is not file-backed or does not have a method
to recover the file-backed filename.
New methods can be made for this generic.
