v0.4.0

Experimental feature

• Support for OTP version 2 (experimental). As OTPv2 has not yet been released
  changes to its codebase could cause errors in otpr or unexpected behaviour
  when used against an OTPv2 instance. This version was tested against commit cce4e7ea.
  Please report any problems in Issues.
  Current known issues:
  • otp_get_isochrone() is only supported in OTPv1 as this feature has been removed
    from OTPv2.
  • The maxWalkDistance parameter used in the otp_get_times() function is treated
    as a hard limit when the mode is either WALK or BICYCLE. This could result in no itinerary being
    returned as the default is 800m. This is different from the behaviour of OTPv1
    where this parameter is effectively ignored when the mode is WALK and not applied at all
    to BICYCLE trips. Workaround: provide a large value to this parameter for these modes.
  • The 'routeType' and 'agencyUrl' columns do not appear in the data frame of
    journey legs as these are not returned by OTPv2.

Deprecated arguments

• otp_connect() no longer uses the optional check argument. The function
  will now always check that the OTP server and specified router are reachable. This
  is because the version of OTP must now be retrieved from the ../otp endpoint
  so that otpr can support OTP versions 1 and 2.

Other

• Compatibility with R 4.0.0. Note: R 4.0.0 requires reinstallation of all packages
  on your system. In particular, make sure that you have re-installed curl,
  as otp_connect() can appear to fail without the reason - that curl has not been
  installed after 4.0.0 - being explicitly reported.
• otp_connect() now retrieves the version of the OTP server. This is contained
  in the otpconnect object that is returned and reported to the user. Note that OTPv2
  does not support named or multiple routers.
• Now also imports the sf package. The st_make_valid() function is used
  in otp_get_isochrone() to correct any geometry errors in the sf object before
  it is returned to the user. OTP appears to return polygons that fail validation
  by st_is_valid from the sf package.
