Error with otp_get_times() about otp-tutorial

[marcusyoung]

That function usually works without an error. Can you please provide your code up to and including that function. Also please confirm what version the running OTP instance is. Thank you.

Thanks so much for getting back to me so quickly!!!

I am using the otp.jar file included in the tutorial folder. Following the tutorial, I start an OTP instance from the command line. then in R, I run:

Accompanying code for Part 3 of OTP Tutorial

Install the otpr package

install.packages("otpr")

Now load the package

library(otpr)

Call otpConnect() to define a connection called otpcon

otpcon <- otp_connect(timezone = "Europe/London")

Call otp_get_times to get attributes of an itinerary

otp_get_times(
otpcon,
fromPlace = c(53.43329,-2.13357),
toPlace = c(53.36274,-2.27293),
mode = 'BUS',
date = '01-19-2021',
time = '08:00:00',
detail=TRUE
)

Please let me know if I need to provide any additional information. Thanks again!!

I'm unable to reproduce this error.

otpcon <- otp_connect(timezone = "Europe/London") wouldn't work as the parameter used in otp_connect() is tz.

With the otpr package loaded can you run sessionInfo() and then provide a screenshot/copy of the returned data.

Thanks

You're so right! I cleared my library and then was unable to successfully run otpcon <- otp_connect(timezone = "Europe/London"), but once I used otpcon <- otp_connect(tz = "Europe/London") and then ran otp_get_times with the detail option, I had no problems.

I suspect it's because I had both the otpr and opentripplanner packages loaded?

Thanks so much for your help!!!

[marcusyoung]

Potentially, yes. The opentripplanner package was forked from otpr some years ago. They both share an otp_connect() function, but that function now differs between the two packages.

Got it, thanks so much for all of your help!!
