R markdown: Issue suppressing progress bar inside function called in R markdown

I am including some R code in Rmarkdown, and I am trying to suppress the progress bar inside a function.

Suppose I have the following function:

func <- function(n){
  pb <- txtProgressBar(min = 1, max = n, style = 3)
  for(i in 1:n){
    Sys.sleep(0.1)
    setTxtProgressBar(pb, i)
  }
  close(pb)
}

and I want to call the function in Rmarkdown like this:

```{r, message=FALSE, progress=FALSE}
func(10)
```

However, even if I set progress = FALSE, the progress bar still shows. Is there a way to suppress it?

You can use:

```{r}
invisible(capture.output(func(10)))
```

which seems to deliver what you want.
