I just found a very useful solution here.

First, include the following chunk:

```{r functions, include=FALSE}
# A function for captioning and referencing images
fig <- local({
    i <- 0
    ref <- list()
    list(
        cap=function(refName, text) {
            i <<- i + 1
            ref[[refName]] <<- i
            paste("Figure ", i, ": ", text, sep="")
        },
        ref=function(refName) {
            ref[[refName]]
        })
})
``` 

After, we can add the caption of the figure/table in the figure chunk options like:

```{r, fig.cap=paste("Your caption.")}

• See that fig.cap works better with paste.
