R markdown: Accessing variable from code chunk (variable scope)

Question

In R markdown (knitr package), can I access a variable within the body of the document that was calculated in a code chunk?

Accepted Answer

Yes. You can simply call any previously evaluated variable inline.

e.g. If you had previously created a `data.frame` in a chunk with `df <- data.frame(x=1:10)`

```
`r max(df$x)`
```

Should produce

```
10
```
