r flex dashboard layout with tabs and panels

Question

I am interested in a flexboard layout with two tabs and within each tab the layout be split into three tiles or panels.

This will give me a layout with three panels which is good.

---
title: "Panels"
output: 
  flexdashboard::flex_dashboard:
    orientation: columns
    vertical_layout: fill
---

```{r setup, include=FALSE}
library(flexdashboard)
```

Column {data-width=650}
-----------------------------------------------------------------------

### Chart A

```{r}
```

Column {data-width=350}
-----------------------------------------------------------------------

### Chart B

```{r}
```

### Chart C

```{r}
```

This will give me a layout with two tabs

---
title: "Tabs"
output: 
  flexdashboard::flex_dashboard:
    orientation: columns
    vertical_layout: fill
---

```{r setup, include=FALSE}
library(flexdashboard)
```

Column {.tabset}
-------------------------------------

### Sheet 1

```{r}
```   

### Sheet 2

```{r}
```

How can I put these two together so that my layout looks like this below

Answer 1

You need to add this under your YAML header in the first example you provided:

Sheet1
===

The === will append tabs to your dashboard.

So it would look like:

---
title: "Panels"
output: 
  flexdashboard::flex_dashboard:
    orientation: columns
    vertical_layout: fill
---
Sheet1
===

```{r setup, include=FALSE}
library(flexdashboard)
```

Column {data-width=650}
-----------------------------------------------------------------------

### Chart A

```{r}
```

Column {data-width=350}
-----------------------------------------------------------------------

### Chart B

```{r}
```

### Chart C

```{r}
```

Sheet2
===
