I do something like
<<echo=f>>=
needed <- function(var){
a <- mean(var)
b <- sd(var)
c <- paste("The mean is ",a," and the var is ",b,collapse="")
return(c)
}
@
\Sexpr{needed(something)}
Wich is to do the macro in R instead of LaTeX2e

Emne: [R] Sweave: R code in self defined TeX-commands
Hi,
I need to produce a standard report for several variables in Sweave and thus
would need the possibility to define a TeX-command which includes
R-code like
\newcommand{\meansd}[1]{The mean is \Sexpr{mean(#1)} and the standard
deviation is \Sexpr{sd(#1)} .
}
and then just write
\meansd{age}
in the latex code to get the whole sentence.
The above does not work, since Sweave ignores the \newcommand and does not
expand the \statistics
Is there an alternative way to achieve this?
Thanks,
