Static summary of which systems provide demographic data

Description

Static summary of which systems provide demographic data

Usage

bike_demographic_data()

Value

A data.frame detailing the kinds of demographic data provided by the different systems

Examples

bike_demographic_data ()
# Examples of filtering data by demographic parameters:
## Not run: 
data_dir <- tempdir ()
bike_write_test_data (data_dir = data_dir)
bikedb <- file.path (data_dir, "testdb")
store_bikedata (data_dir = data_dir, bikedb = bikedb)
# create database indexes for quicker access:
index_bikedata_db (bikedb = bikedb)

sum (bike_tripmat (bikedb = bikedb, city = "bo")) # 200 trips
sum (bike_tripmat (bikedb = bikedb, city = "bo", birth_year = 1990)) # 9
sum (bike_tripmat (bikedb = bikedb, city = "bo", gender = "f")) # 22
sum (bike_tripmat (bikedb = bikedb, city = "bo", gender = 2)) # 22
sum (bike_tripmat (bikedb = bikedb, city = "bo", gender = 1)) # = m; 68
sum (bike_tripmat (bikedb = bikedb, city = "bo", gender = 0)) # = n; 9
# Sum of gender-filtered trips is less than total because \code{gender = 0}
# extracts all registered users with unspecified genders, while without
# gender filtering extracts all trips for registered and non-registered
# users.

# The following generates an error because Washinton DC's DivvyBike system
# does not provide demographic data
sum (bike_tripmat (bikedb = bikedb, city = "dc", birth_year = 1990))
bike_rm_test_data (data_dir = data_dir)
bike_rm_db (bikedb)

## End(Not run)
