## 6.10 The local FDR



```{r,echo=F,out.width='40%',fig.cap='While the frequentist only has the currently available data, the Bayesian can draw on her understanding of the world or on previous experience. As a Bayesian, she would know enough about physics to understand that our sun’s mass is too small to become a nova. Even if she does not know physics, she might be an empirical Bayesian and draw her prior from a myriad previous days where the sun did not go nova.',fig.margin=F,fig.align='center'}
knitr::include_graphics("./frequentists_vs_bayesians.png")
```

    

Answer 1

You could use the \captionof macro from the caption package to place the caption in a column besides the image:
