Remove brackets in Sweave output

I want to know if there is a way to print R object directly in a text (Sweave), but directly in a line of text.

I'd like to print this code

\documentclass{article}

\begin{document}
\SweaveOpts{concordance=TRUE}

YO MANNNNNNN 2+2 = 
<<here, results=tex, echo=FALSE>>=
2+2
@
YEAHHHH!

\end{document}

And I want an output similar to this: 

YO MANNNNNNN 2+2 = 4 YEAHHHH!

But, R is adding the answer brackets like this 

YO MANNNNNNN 2+2 = [1] 4YEAHHHH!
Solution

  • Code:

    \documentclass{article}

\begin{document}
% \SweaveOpts{concordance=TRUE}

YO MANNNNNNN 2+2 = \Sexpr{2+2} YEAHHHH! 

\end{document}

    n.b. For me commenting out \SweaveOpts{concordance=TRUE} worked just fine, but you made need to uncomment depending on your setup.

    Prints:

    YO MANNNNNNN 2+2 = 4 YEAHHHH!

    Update - extra info per comment...

    You can define an object within a 'chunk' to be later evaluated in line using \Sexpr{}

    <<somechunk, results='tex',echo=FALSE, results='hide'>>=
x <- 2
@

Inline evaluation of x prints the number \Sexpr{x}.
