Presence inside geofence - Ray casting algorithm in R

Watch this video to get a better understanding of the algorithm --> https://invidious.osi.kr/watch?v=01E0RGb2WzoOther source --> https://it.wikipedia.org/wiki/Ray_tracing#Algoritmo_di_Ray_casting The code is written in R. You need to readapt it to your data to make it work, butthe main function is ready to be used (try it on RStudio). I hope it can help andsave you some time.I am not a programmer, so if you find an error or a better way to do it, pleasecontact me and I'll correct it as soon as possible.Raffaello Barri Update 13/Jun/2022Please refer to this workflow:https://kni.me/w/8G2SCxMEY3mD4iiM In geofence?
