[R] Novice Alert!: odfWeave help!

[Jan van der Laan]

Step by step:

1. Create a new document in Open/LibreOffice
2. Copy/paste the following text into the document (as an example)

<<helloworld>>=
cat("Hello, world")
@

2. Save the file (e.g. "hello.odt")
3. Start R (if not already) shouldn't matter if its plain R/RStudio
4. Change working directory to the folder in which you odt-document resides

setwd("/path/to/your/file")

4. Load odfWeave

library(odfWeave)

5. odfWeave your document. All code-chunks are taken from your  
document, executed in R and the output of the R-commands is inserted  
into the resulting odt-document.

odfWeave("hello.odt", "hello_out.odt")

You can now open "hello_out.odt" (or whatever you named it) and see  
the resulting output.


HTH,

Jan
