Usage

Arguments

format	the data format read by the writer Should be a length 1 character vector.
writer	the writer function. See details.

The writer function should accept 'data' with the data as its first argument, 'resourcename' the name of the resource to which the data set belongs, 'datapackage' that datapackage to which the data should be written.

Examples

# Add a very simple writer for json
json_writer <- function(data, resourcename, datapackage, ...) {
  dataresource <- dpresource(datapackage, resourcename)
  path <- dppath(dataresource, fullpath = TRUE)
  jsonlite::write_json(data, path)
}
