Given a set of geographic coordinates and values associated with those
points, i want to interpolate data and generate heat map on google maps
with colors based on the values. Can you guide me to some R examples that
achieve this? I have to create this from scratch...the data I have is like
latitude ; longitude ; value ; color(i can provide the color input at these
points if required from another application).

I am trying to generate something like this ->

I have looked at the examples in Rgooglemaps and ggplot2 packages but none
of them seem to give such an output.

Kindly guide me regarding this.

Thanks and Regards
