The R-Spain Conferences have been taking place since 2009 as an expression of the growing interest that R elicits in many fileds. The organisers are the Comunidad R Hispano (R-es). The community supports many groups and initiatives aimed to develop R knowledge and widen its use.
To attend the talks by streaming (they are in Spanish) you must registrate.
There is also a scientific programme with the presentations (some in English) here.
