Requirements[edit]
- R is a free software environment for statistical computing and graphics. It needs to be installed (probably available in your Linux distribution) and in the PATH: the command
Rshould work on the command line. - ImageMagick is a software suite to create, edit, compose, or convert bitmap images. It need to be installed (probably available in your Linux distribution) and in the PATH: the command
convertshould work on the command line. If you enabled TeX then it should have been installed already.
Download[edit]
You can obtain the extension at this offsite location.
Installation[edit]
The installation instruction are for version 0.11 of the extension. For earlier versions, please consult documentation for your version of the extension.
- Extract the downloaded files into your extensions directory.
- Add
to the bottom of LocalSettings.php.require_once( "$IP/extensions/R/R.php" );
- Copy Rcgi.php to the root directory of your wiki
cp extensions/R/Rcgi.php .
- Initial installation can now be verified through Special:Version of your wiki.
- Further information can be found under Special:R page of your wiki.
Examples[edit]
All examples are done with version v0.10 of the extension. They may not work with other versions, please consult documentation for your version of the extension.
Usage[edit]
| Example | Page (edit mode) | Page (view mode) |
|---|---|---|
| Raw output |
<R>1:10</R> |
 |
| Raw iframe output |
<R iframe="width:100%;height:40px">1:10</R> |
 |
| HTML output |
<R output="html" iframe="width:100%;height:250px;"> prob=0.15; nmin=1; nmax=15; x=6 m <-pbinom(rep(0:x, each = nmax-nmin+1), rep(nmin:nmax,x), prob) dim(m) <- c(nmax-nmin+1,x+1) m <- t(m) colnames(m) <- format(nmin:nmax) rownames(m) <- format(0:x) outHTML(rhtml, m, title="x\n", format="f", digits=4) </R> |
 |
| Wiki output |
<R output="wiki">
x<-matrix(1:12,ncol=3)
rownames(x) <- sprintf("row %i", 1:4)
colnames(x) <- sprintf("col %i", 1:3)
out.Wiki(x, title="x")
</R>

| Graphics |
<R output="display"> pdf(rpdf) plot(1:10, 1:10) </R> |
 |
| Complex graphics |
<R output="display" iframe="width:400px;height:400px">
pdf(rpdf, width=5, height=5)
n <- 10
prob <- 0.2
x <- seq(0, n, 1)
p <- dbinom(x, n, prob)
param <- list(n, prob)
main <- c("Binomialverteilung - Wahrscheinlichkeitsfunktion",
paste (c("Stichprobenumfang n", "Wahrscheinlichkeit p"), param, sep="="))
plot(x,p, type="h", main=main)
