R flexdashboard removes the title bar

Question

I am working on a project using rMarkdownand flexdashboardpackage from rStudio. Everything is going well. But I would like to remove the blue caption that you see at the top of the image.

We drop this html page into the window so that it becomes the second title bar, which looks awful. Is there a function in flexdashboardto delete this entire device?

Here is YAML and the first fragment that you see just below the blue bar in the photo. Any suggestion would be greatly appreciated.

  flexdashboard::flex_dashboard:
    orientation: rows

```{r setup, include=FALSE, message=FALSE, warning=FALSE, echo=TRUE}

```

```{r, aarState, message=FALSE, warning=FALSE}

library(flexdashboard)
library(rbokeh)
#load state-wide age adjusted rates

aar<-read.csv("stateAAR.csv")
figure(title=" Age Adjusted Rates by Year",width= 1500, height =600) %>%
  ly_segments(year, lci*100000, year, uci*100000, data=aar, color = "#b37700", width = 1) %>%
  ly_points(year, adj.rate*100000, glyph = 21, size=6, data = aar, hover= "<strong>Rate per 100,000:</strong> @rateHundThou </br> <strong>Upper Confidence:</strong> @uciHT </br><strong> Lower Confidence:</strong> @lciHT " , color="#666622" )%>%
