Résumé :	Publishing ornithological data requires the application of adequate statistical methods. With the improvement of methods, software requirements are arising, but available proprietary programs are often far beyond the financial limits of the users. The statistic package R is a free but nevertheless very sophisticated alternative. Regrettably, it is not easy to get started with R since it is not clickable and needs the typing of code. This article is a step by step introduction for R-beginners. The reader can experience the input of data, their handling and visualisation at his computer. We guide the user through a t-test and develop a simple linear model including analysis of residuals. Finally, we suggest books for further reading.
