Write GTFS files

Source: R/write_gtfs.R
write_gtfs.Rd

Writes GTFS objects as GTFS .zip files.

Usage

write_gtfs(
  gtfs,
  path,
  files = NULL,
  standard_only = FALSE,
  as_dir = FALSE,
  overwrite = TRUE,
  quiet = TRUE
)

Arguments

gtfs

A GTFS object, as created by read_gtfs().

path

The path to the .zip file in which the feed should be written to.

files

A character vector containing the name of the elements to be written to the feed. If NULL (the default), all elements inside the GTFS object are written.

standard_only

Whether to write only standard files and fields (defaults to FALSE, which doesn't drop extra files and fields).

as_dir

Whether to write the feed as a directory, instead of a .zip file (defaults to FALSE, which means that the field is written as a zip file).

overwrite

Whether to overwrite existing .zip file (defaults to TRUE).

quiet

Whether to hide log messages and progress bars (defaults to TRUE).

Value

Invisibly returns the same GTFS object passed to the gtfs parameter.
