The ggplot syntax may look a bit strange in the beginning but there are really good tutorials out there to help you start. In this post I’ll explain how to plot multiple ggplots on one page, simil...

Working with spatial data is a key feature in ecological research. Using R to handle this type of data has the great advantage of keeping both variable extraction and modelling in the same environment, instead of recurring to external GIS softwares to compute some variables and then turning to R for modelling. In this example I’ll use as my bas...
