Suppose we plot a number of points (latitude, longitude) on the google map using Plot Google map package of R. These points are classified on the basis of unique vehicle-id i.e. a point to represent where a particular vehicle stopped. So, the data consists of numerous vehicles. Now, I just wanted to know whether its possible if we click on a particular legend(marker) on the Google map, then all the legend(marker) of that particular vehicle-id gets highlighted. I just wanted to know whether it could be done or how to do it.
