+#### Rstudio tutorial
+I choose to follow the Rstudio tutorial even if I already know how to produce Rmarkdown files, but it would be cool to try later OrgMode, so that I could use Emacs to do eveything (while fore now I am only using it to produce Latex documents).
+
+Something I didn't know: when you use another langage than R (for example when I use some pieces of bash/python for OBITOOLS pipelines), the variables generated in a chunck are not kept in memory and cannot be used from one chunk to another (which is the case for R code).
