If you want to help or add things, you can: just press edit. You can discuss top level planning issues here.
If you see an entry you'd like to fix then go ahead: Pages can easily be recovered if you accidentally destroy something.


  • Just edit — if you break something then ask one of the wiki contacts for assistance.
  • If you create a new page, set its parent page so it gets included in the contents (options:parent).
  • Provide references
  • Ensure example code is standalone.
    • Use "require" to indicate what libraries are needed.
    • Include an example of the output you get (this is especially important for graphs so you see what the code does).
  • If you want a change that you are unable to do yourself, add a footnote reading "FIXME!", plus the problem.

Notes for the reader

All examples should be standalone, but it is assumed you have the required packages installed. If on running a require command you see an error like the following:

# Loading required package: lme4
# Warning message:
# In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE,  :
#  there is no package called 'lme4'

that means you need to install the package. Do so by typing

install.packages("packagename", dep=T)
