Dear useRs,
I'm writing regular survey reports using Sweave. Each
report has several sections along the lines of:
\section*{Disease X}
<<MapX,fig=TRUE,echo=FALSE>>image(vectorx,vectory,matrixz)
@
Notes with or without Sexpr{a}.
\vfill
\pagebreak
\section*{Disease Y}
<<MapY,fig=TRUE,echo=FALSE>>...etc.
Often one or more of the diseases is not observed (all
values in matrixz are 0), in which case I would prefer
not to display the section at all. Does any one no
whether it is possible automate this with Sweave?

Hi Mikkel,
One way would be to use cat("\\section{", diseaseName,
"}\n") with if
(sum(matrixz) > 0) within a for loop (or perhaps using one of the
apply family of functions (probably lapply?)). To some extent this
by-passes the separation of code and documentation that literal
programming is about but I couldn't think of a better way to solve the
problem just now. Sorry this is not a full worked example, but I'm
off to the pub now for a few pints to welcome 2005.

Frank Harrel proposed the following solution:
\ifnum\Sexpr{x}=1
\section{}
. . .
\fi
and it works. Amazingly simple!
cheers,
