Is there any way to have Sexpr span multiple lines?
For input or output? I.e. do you want
\Sexpr{x +
y}
or do you want the value to display on multiple lines?
I think you can't do the first. To do the second, returning a character
value with an embedded newline should work. For example,
<<echo=FALSE>>=
string <- "this goes on \\\\\\\\\n two lines"
@
\Sexpr{string}
(I think you really need all those escapes to get two backslashes in the
output!)
I don't know if it will happen for 2.10.x, but I would like to extend
\Sexpr to be just as flexible as the <<>>= notation, by putting the
Sweave options in a Latex-like option:
\Sexpr[fig=true]{ plot(rnorm(1000))}
You can do this now in R-devel in the new Sweave-like syntax in Rd files
(except they don't support figs yet), but not yet in the original.
