Examples

# NOT RUN {
data_dir <- tempdir ()
bike_write_test_data (data_dir = data_dir)
# or download some real data!
# dl_bikedata (city = 'la', 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)

stations <- bike_stations (bikedb)
head (stations)

bike_rm_test_data (data_dir = data_dir)
bike_rm_db (bikedb)
# don't forget to remove real data!
# file.remove (list.files (data_dir, pattern = '.zip'))
# }
