hi @e-kotov . I love the idea! Are you planning to put this on CRAN ?

Are you planning to put this on CRAN ?

I don't know. I just really needed this for my own work, and like with many other things recently, I just decided it is easier to "perfect" it to a minimal working package draft and share, perhaps someone would find it useful. But as of right now, this serves my purposes so I'm just going to continue with my work.

I would actually be happy to pass it over to ipeaGIT org right now, or eventually, if you'd like that. And then perhaps someone would put it on CRAN and/or maintain it. I may find time to make it CRAN worthy, but I would have no concrete timeline for that any time soon (though depending on my own usage, I may of course push some updates to it).

@BardyBard @rafapereirabr is there some internal R5 Java API that I could use to quickly get the extent of the network to automatically center the map on it? I don't want to use the transit_network_to_sf as it takes too much time, the app will start slowly.

Not that I know of.

Hi @e-kotov this is beautiful.

You can access the java pointer to the R5RCore directly through network@jcore. The core holds a TransportNetwork and the TransportNetwork has a gridpoint set, which I think is what you're looking for.

@BardyBard thanks, I hope this will be faster then materializing the whole network as sf object! I will give it a try!
