Drawing great circles and avoiding horizontal line wrap

[qwertytam]

Hi, using this code for drawing great circle paths between locations where the longitude is greater than 180 degrees, produces horizontal lines when plotted where the line is in effect wrapping around - see here under the section 'Correcting gcIntermediate' for a resolution of a similar issue with gcIntermediate. I'm trying to think through how to resolve the similar problem with the approach outlined here, but haven't come up with anything yet.

Looks like st_wrap_dateline to the rescue!
An extra line of code and then plotting the routes_sf_wrap looks to resolve the issue

# Wrap great circles to avoid horizontal lines when plotted
routes_sf_wrap <- st_wrap_dateline(routes_sf_tidy,
                                   options=c("WRAPDATELINE=YES",
                                             "DATELINEOFFSET=180"))
