R help - Mar 2012 - Making Knitr work

Might not be the best place to ask, but i could get lucky..

I have setup an eclipse environment to write sweave files lately and wanted to
switch to knitr. I could get it to work on easy files, but my earlier written
sweave file fails to be knit properly.

Here is the error message:

Quitting from lines 273-276: Error in setwd(base.dir) : kann Arbeitsverzeichnis
nicht wechseln (it says: cannot change workspace)

The chunk that is 273-276:

<<getdata,echo=F>>library(e1071)
source("/src/TestRandomStuff.R")
allData<-createNormallyDistributedClasses(2, c(-2,2), 50, 2)
@

Further mentions of the chunk in console (its strangely listed twice):

|>>>>>>>>>>>>>>>>>>>>>>>>
|  37%
label: getdata (with options) 
List of 1
 $ echo: logi FALSE

label: getdata (with options) 
List of 1
 $ echo:length 1 F
  ..- attr(*, "id")= int 98

I believe Arbeitsverzeichnis means working directory, not workspace.

It would seem that your code calls the function setwd (set working
directory) which fails. Most likely reasons: base.dir is not defined,
or it is defined relative to a reference directory but the current
working directory is different.

Peter

You must have set the package option 'base.dir'
(opts_knit$set(base.dir = ....)), and this directory does not exist.

I do not recommend you to use this option unless you really understand it.
