I like Sweave, which I consider to be a great contribution. I have just
written a .Rnw document that comes to about 6 pages of mixed code and
mathematical explanation. Now I want to turn the R code into a function. My
R code currently contains statements like N<-1000 and theta<- pi/10. In the
next version of the document, I want N and theta to be parameters of a
function, so that they can be easily varied. My explanation of the code is
still valid, and it seems to me that, if I only knew how to manage the
trick, I would need to change almost nothing in the latex.

The document contains about 6 different code chunks, and 7 different chunks of latex.

One other point is that I will want to export some of the variables computed in the function to outside the function, so that they are not variables local to the function body. I mention this only because it may affect the solution, if any, to my problem.

Thanks for any help

David
