Problem with renderText inline in header in interactive .Rmd file

[Kent Johnson]

Hi,

I'm having a problem with inline R code using renderText() in a markdown header. Easiest to just show an example:

---
title: "Test"
output: html_document
runtime: shiny
---


```{r, echo=FALSE}
inputPanel(
  selectInput("n_breaks", label = "Number of bins:",
              choices = c(10, 20, 35, 50), selected = 20)
)


breaks = reactive({input$n_breaks})
```


### breaks = `r renderText(breaks())` breaks = `r renderText(breaks())`

There are two problems. The major one is that the renderText() doesn't produce any text. Removing the second renderText() fixes that. A less serious problem is that the text "-breaks-" class="section level3">" is displayed above the header.

Is there a fix for this?

Thanks,

Kent
