[R] Do you keep an archive of "useful" R code? and if so - how?

Sun Nov 22 20:32:11 CET 2009

I accidentally sent this directly to the author and didn't reply to the
whole list, I am sorry, I need to remember to hit reply all instead of reply
to the R help list, heres my message:

I keep a separate R file of code I commonly use but more generic. So if I am
making contingency tables I say:

ftable(category, category[top])

or if I am wanting to subset data:

subset2$X5<-recode(subset2$X5, "6:10=1:5")

things like that, generic code that I can refer to and include my variables
in as necessary (as you can tell the "top" mark I made in ftable isn't in
the code but reminds me how the table structures itself. Since I am a newbie
at R I am still keeping notes, I do this for importing things, also
graphics:

xyplot(value~X1,data=subset1,groups=factor(X2),
     type=c("b","g"),ylim=c(0,1),xlim=c(1,5),lwd=1,cex = 1,
     plot.points = TRUE,auto.key = list(points = TRUE,lines = TRUE, space =
"inside"),
     label.curves=FALSE,xlab = "x axis title", ylab = " y axis title ")

so it just lets me organize my codes on my local system. R wiki is ok, but
will be much better as people expand it, I am sure very soon it will grow
exponentially as a good resource. 

(as you can tell some of the code I save includes old variable names instead
of neutral ones, but easy enough to change).

Marc and Barry, many thanks for your detailed answers.

Marc -
I thank you for the links and ideas. Thanks to your advice I will look more
into SVN in the future, although it sounds on the surface to require some
learning curve, so It could take me some time to start using it.

Barry -
I am actually a blog builder in my side profession, I already built myself a
blog called:
r-statistics.com
On which I intend to put up good code I will come across.  The problem with
it though is that I don't see blogs as a good information management system.
Since on a blog one is open to the public and doesn't want to leave half
scribles of thoughts (which IS what ends up happening when managing snippets
of code).  Also, blogging is not build for easy hierarchical ordering.

The idea of a wiki is more appealing.
BTW - another suggestion I got was using MS onenote. Although it is not open
source (which is my preference as well), I understood it offers a powerful
solution.

I hope more people will share how they manage their snippets of code.

Best to all of you,
Tal
