Subsampling for dummies
A little piece of code dealing with the subsampling of matrices, in R. Useful if you want to use something akin to bootstrap, or just check the size of your sample with regard to various statistics.
Drawing a trophic network (part 2)
Following discussion on the comments of the previous post, I thought about how it was possible to draw links going in several directions (i.e. there are no ‘clear’ differences between the levels, and species from level n can interact with species of level n, n+1, n-1, n±k, etc). This is now done, with a code 
Draw a trophic network with n levels
I published a short function to draw trophic networks with several levels, with links going from level n+1 to level n only. It will only be of interest for people working in ecology (but if you see another possible use, please let me know). It is available here – with examples. If I continue to 
Draw a trophic network with n levels
In the last few weeks, I started focusing more on more of trophic systems with three levels or more. I wanted something to visualize the resulting trophic network, so I came up with a little R function called draw.mnet (which stands for draw a multiple-levels network).
Getting data from an image (introductory post)
Hi there! This blog will be dedicated to data visualization in R. Why? Two reasons. First, when it comes to statistics, I am always starting by some exploratory analyses, mostly with plots. And when I handle large quantities of data, it’s nice to make some graphs to get a grasp about what is going on.
