Ecological data sets in R-core

If you are using R, then you are probably familiar with the mtcars data set, that is used in many R tutorials. The “car analogy” is so common in text books, that this so-called technique has its own Wikipedia page. For the rest of us, who don’t understand anything about motor cars, R-core comes with a wide selection of example data sets, some of which relate to ecology or biodiversity.

  1. Hello √Ālavaro, I have been reading your posts with interest. I am the technical lead for data and analytics at the Taskforce on Nature-related Financial Disclosures (TNFD). As you are no doubt aware and indeed highlight, there are numerous gaps and challenges in nature-related data and it something we are trying to address. I’d be interested in having a chat sometime. Many thanks James
