A 30h R software course started the 19th of October in the Ecology Institute of UMSA (La Paz, Bolivia). It is organized by IRD in collaboration with the “Centro de Análisis Espacial”. François Rebaudo, with the help of Quentin Struelens (UMR EGCE), proposes a full training on the basis of this software. R is a programmation language and a free software for scientific data treatment, statistical analysis and graph creation (r-project.org). It is nowadays the most powerful and popular tool for the treatment of scientific data. This course is open to everyone, students as well as teachers and scientists.
