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, Martin Posch
