Functions, especially user-written
========================================================

```{r eval = FALSE, echo = FALSE}
## used during debugging
search()
```

> JB: this is not a high priority for me to write up myself. So I include links to some perfectly good material that others have written. If you find more resources, feel free to suggest.

[Section 10 Writing your own functions](http://cran.r-project.org/doc/manuals/R-intro.html#Writing-your-own-functions) from the official document, An Introduction to R

[User-written functions](http://www.statmethods.net/management/userfunctions.html) on the Quick-R website. Very minimal. The slightly expanded version -- 2 whole pages! -- in the R in Action Book version is much nicer, but oh well.

The [block on functions](http://vscarl1.stat.ubc.ca/SCARL/workshops/2013-09_biodiversity/block7.html), prepared by Davor Cubranic, from the September 2013 R Workshop run by [SCARL](http://www.stat.ubc.ca/SCARL/) for the [BRITE](http://www.biodiversity.ubc.ca/BRITE/) training program

Nice R code guides (for better or worse, kind of wordy, like my stuff)

  * Their "total beginner" guide to [Writing functions](http://nicercode.github.io/intro/writing-functions.html)

  * Slightly more advanced: [Using functions to simplify your scripts](http://nicercode.github.io/guides/functions/)

[Functions](http://adv-r.had.co.nz/Functions.html) from Advanced R Programming by Hadley Wickham

```{r  eval = FALSE, echo = FALSE}
## used during debugging
search()
#detach(pos = grep("gdata", search()))
```
