Introduction

We will often wish to present our findings at conferences and other gatherings where a good presentation of tables and graphics are required.

Flexdashboard is a great way to accomplish this.

To get up to speed in this area you will need to make good use of the online resources.

I will outline the basic ideas and you can perfect the details by inspecting the above website.

The first thing to notice is that there is an orientation

Orientation

You can either orient the document by columns (default) or rows. This can be set in the YAML header using the keyword orientation which you can set as rows or columns.

Example

output: 
  flexdashboard::flex_dashboard:
    orientation: rows

This will cause that all charts will populate the knitted document row-wise.

Whereas the following

output: 
  flexdashboard::flex_dashboard:
    orientation: columns

will populate the knitted document by columns.

The meaning of headings

Normally when you make a document you would have # Heading then ## Sub heading and then ### Sub Sub heading

In flex_dashboard the hashes mean something different.

Hash headings

The first hash # page denotes a new page (this will appear in a menu)

The second hash ## Column will produce a new column if the orientation was columns. This can be denoted differently. You could use

Column
------------------------------------

The third hash ### Chart would make space for a chart or table etc

Example

what would the following dashboard code produce when knitted?

---
title: "Column Orientation"
output: flexdashboard::flex_dashboard
---


Column
-------------------------------------

### Chart 1

```r

Column

Chart 2

Chart 3

Notice that the YAML header has no orientation set. So it will be the default orientation: `columns`

The second order header:

Column

Will prepare a column for the first chart which is set with the three hashes

Chart 1

The last code produces a new column into which two charts 2, 3 will be rendered.

Column

Chart 2

Chart 3

# Problem 1

We will use our current understanding to solve a problem.

Suppose we want want to have a row of 2 charts followed by one row containing a third chart.

Produce the code to make the document.

---

title: "Problem 1" output: flexdashboard::flex_dashboard: orientation: rows

---

Row

Chart 1

Chart 2

Row

Chart 3

# Problem 2

Suppose we wish to have a large number of charts on a page. This can be accomplished by using tabsets. You probably are familiar with  these in your browsers.

Produce the code that will create three tabset charts in one row and 4 tabset charts in a second row.

---

title: "Tabset Column" output: flexdashboard::flex_dashboard: orientation: rows

---

Column {.tabset}

Chart 1

Chart 2

Chart 3

Column {.tabset}

Chart 4

Chart 5

Chart 6

```
