Control alignment of two side-by-side plots in knitr

Tags:

I cannot figure out how to arrange two side-by-side plots as explained in the knitr graphics manual page 2 (http://yihui.name/knitr/demo/graphics/). I use the following MWE and the output is below. I would like them to be aligned as shown in the manual for the two cars plots (also on page 2 of the manual). The pdf is generated in RStudio (Knit to PDF).

--- title: "Untitled" output: pdf_document ---  ## R Markdown  ```{r,echo=FALSE,out.width='.49\\linewidth', fig.width=3, fig.height=3}  barplot(1:4) barplot(4:7)  ``` 

enter image description here

To center two plots you can add fig.align='center'to your chunk options. If it produces one plot above the other add also fig.show='hold'. The result should be two centered graphs. Result

So your final chunk option should look something like:

{r,echo=FALSE, out.width='.49\\linewidth', fig.width=3, fig.height=3,fig.show='hold',fig.align='center'}
