Since 2009 I have been working on Denny Borsboom’s *psychosystems project*. For more information on this please visit the website:

## R

Most of my work involves R in some way. R is an open source statistical programming language in which you are able to do pretty much everything you ever wanted to do (statistically that is). It is available from:

Some other useful links for R are:

- http://www.statmethods.net/ for tutorials on how to perform basic statistics in R
- http://stackoverflow.com/questions/tagged/r for programming technical questions related to R (see below)
- http://stats.stackexchange.com/questions/tagged/r for statistical questions related to R (see below)

## LaTeX

LaTeX is a, open source typesetting system useful for writing scientific reports. A place to start is:

Personally I use the MikTeX distribution on Windows (http://miktex.org/) and the TeXlive distribution on Linux (http://www.tug.org/texlive/). Some more useful links for LaTeX are:

- http://pineda-krch.com/2011/01/17/the-joy-of-sweave/ for an introduction on incorporating R codes in LaTeX using Sweave
- http://ftp.snt.utwente.nl/pub/software/tex/macros/latex/contrib/beamer/doc/beameruserguide.pdf for using LaTeX to make presentation slides
- http://ctan.org/tex-archive/macros/latex/contrib/apa for easily writing your documents in APA style
- http://tex.stackexchange.com/ The stackexchange site dedicated to LaTeX (see below)

## Stackexchange

Already mentioned several times above, http://stackexchange.com/ is a series of question and answer sites. It can be a very useful place to start finding the answer to all of life’s problems! For a lot of detail on how these sites work see the FAQ:

http://meta.stackoverflow.com/q/7931/157142

The ones that I most often read are:

- http://stackoverflow.com/ I am very active on this site in the R corner, but this site can be used for any programming technical question related to any programming language
- http://stats.stackexchange.com/ AKA http://www.crossvalidated.com/ is a site where you can ask any question related to statistics
- http://tex.stackexchange.com/ for questions related to LaTeX
- http://superuser.com/ for questions related to how to do anything on your computer
- http://askubuntu.com/ for questions related to Ubuntu
