What I wnat to achieve is the following: I want the PNG to be transparent
and it should overlay the entire map. Right now, the plot window is too
small. Thanks a lot for all the replies thus far. Really appreciate it.

Dear list,
I'm having troubles with matching the Google Map's bounding box with the
window of plot.ppp (spatstat). My coordinates are in longitude / latitude.
Ultimately, I'd like to have the bounding box of my Google Maps map to be
equal to the rectangle (window) in R. I've seen suggestions that

Location-Based Services, the users tend to be interested in local / nearby
points of interests. I'm looking for techniques to allow
Dear Tom,
Actually, R complains about duplicate points. I'm pretty sure some
restaurants are really close to each other, or perhaps in the same building.
Could be some geocoding errors as well. If I were to 'wiggle' the data,
would this be dependent on the resolution of the dataset? I'm still figu

Thanks :) Actually, I'm busy with developing a Location-Based Service (a
restaurant finder to be precise) utilising SDA. The goal of my research is
to integrate SDA in an LBS. For this purpose, I've gathered abo
