I’m very new to RStudio, so apologies in advance for a messy, inefficient program. I’m working on plotting access to a single point in Montreal– the central station– and the plots I’m coming up with do not seem to be producing sensible output, so I feel like I’m missing some critical piece that would make this all flow together nicely. The current map produced at the end of this analysis appear to be very random–in my result, hexagons close to the station are coded as needing the max transit time to reach.
