I wonder how to show the R Chunk Code output after whole block of R Chunk Code not the output after each code line.
\documentclass{article}
\begin{document}
<< Test >>=
1:10
args(lm)
@
\end{document}
Are you writing in Rmarkdown ?? If so, there is an option you can add in R chunk like
```{r,results = "hold"}
your R code
```
Otherwise you should figure out how to give this argument to knitr while converting.
