I'm a biologist, mostly working in theoretical aspects of animal populations as well as solving 1001 other little problems. I spend my days in the coding dungeon and my tool of trade is R. I find it very useful for running simulations, doing data manipulation, statistics and shooting oneself in the foot (fortunes() pun intended). I am no stranger to field biology, where I mostly work with plants, butterflies and hoverflies.

I am also a PhD candidate in biostatistics at University of Ljubljana. I work with capture-mark recapture techniques and I fancy simulations. My other interests are computer vision, ecological modeling, data visualization and algorithms.

You should mention you cross-posted at r-sig-geo mailing list as well.

comment Checking if Lng and Lat fall inside polygons from ESRI Shape file
@MoustafaAlzantot please edit your original question, not everyone reads comments. Plus, you have greater flexibility regarding code folding and syntax highlighting.

@MoustafaAlzantot What's the exact command you're using to import data using readOGR?

comment how to overlay a polygon over SpatialPointsDataFrame and preserving the SPDF data?
Great, this also works for multiple polygons (I've added an example to play with into Joshua's answer).

comment How to extract values from rasters at location of points in R?
What about something along the lines of cbind(coordinates(presencias), variables_presencia)? You can then convert to SPDF using coordinates(result) <- ~ X + Y and you can use the plethora of methods designed for spatial objects again.

Shouldn't the values correspond to the coordinates of your presencias?
