Back from a short visit to Barcelona where I’ve been for a “Correspondence Analysis in R” workshop with Michael Greenacre and Oleg Nenadić. Even though we’ve been busy with R programming and stuff, we still managed to see some of the city and visit Gaudi’s Park Güell, Casa Milà and Sagrada Família.

Ευχαριστώ πολύ Michael for your kind invitation and your hospitality.
