Hi professors I'm finding the best package in R for manage a big database about vessels. I need to divided the travel of each boat into tracks. I have GPS points.
I would join these points in a line on the map. I make that with the function "lines", but I can't divided by vessel or by track, I saw several packages, for tracking animals but they had specifically variables. And I don't add others like "type","destination" or "status". Can you give me a suggestion, please [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
