Description

R program offers a powerful tool for analysing and visualising data, and in recent years it became very popular among ecologists (and not only them). It offers great freedom in analysing, manipulating and visualising any type of data, which is not something you can do in clickable software like SAS, SPSS or STATISTICA.
