CSS Flexible Boxes 기반의 FlexDashBoard

FlexDashboard

개인적으로  굳이 runtime:shiny 안 쓰고, 단지 flexdashboard만을 사용하여 껍데기를 구성하여(Html 맹글어서 접속하는데 사용하고)
별도의 Shiny App을 embedded하는게 낫지 않을까 싶다. 

패키지 설치

> install.packages("flexdashboard")

---
title: "Flexboard"
output: 
    flexdashboard::flex_dashboard:
    orientation: rows
vertical_layout: fill
---
    
```{r global, include=FALSE}
```

FlexDashboard 에 Shiny 적용 (runtime: shiny)

http://rmarkdown.rstudio.com/flexdashboard/layouts.html#input_sidebar_(global)

1. Layout

 #     (======)
##   (——)

Single Column (Fill, scroll), Multiple Columns, Multiple Rows

  • YAML헤더에 runtime: shiny 추가
  • 첫번째 Column에 {.sidebar} 추가

2. Components

### 이하의 요소들은 모두 컴포넌트 (html widgets, R plot, table, value box, gauge ….)

Output으로 flexdashboard 팩키지의 flex_dashboard함수를 사용한다. 

ex1> With Sidebar

문제점: 상단 메뉴가 변해도  Sidebar가 안 변함.

ex2> Without  Sidebar, Embeding Shiny

https://beta.rstudioconnect.com/jjallaire/shiny-embedding/

title: "flexdashboard: Shiny Embedding"
output: 
    flexdashboard::flex_dashboard:
    #social: menu
source_code: embed 
runtime: shiny
---
    
```{r global, include=FALSE}
library(datasets)
data(WorldPhones)
```

Module
============================================================
### Embedding a Shiny Module

```{r, include=FALSE}
############################################################
##
## Shiny module definition (typically using separate Rscript)
##
############################################################
# UI function
worldPhonesUI <- function(id) {
    ns <- NS(id)
    fillCol(height = 600, flex = c(NA, 1), 
            inputPanel(
                selectInput(ns("region"), "Region:", choices = colnames(WorldPhones))
            ),
            plotOutput(ns("phonePlot"), height = "100%")
    )
}

# Server function
worldPhones <- function(input, output, session) {
    output$phonePlot <- renderPlot({
        barplot(WorldPhones[,input$region]*1000, 
                ylab = "Number of Telephones", xlab = "Year")
    })
}
```

```{r}
# Include the module
worldPhonesUI("phones")
callModule(worldPhones, "phones")
```

Inline App
=======================================================================
### Inline Shiny App via shinyApp
    
```{r}
shinyApp(
    ui = fillPage(
        fillCol(flex = c(NA, 1), 
                inputPanel(
                    selectInput("region", "Region:", choices = colnames(WorldPhones))
                ),
                plotOutput("phonePlot", height = "100%")
        )
    ),
    server = function(input, output) {
        output$phonePlot <- renderPlot({
            barplot(WorldPhones[,input$region]*1000, 
                    ylab = "Number of Telephones", xlab = "Year")
        })
    },
    options = list(height = 600)
)
```

External App
=======================================================================
### External Shiny App via shinyAppDir
    
```{r}
shinyAppDir(
    system.file("examples/06_tabsets", package="shiny"),
    options = list(height=850)
)
```

 

컨터이너의 크기에 맞게, Flexible하게 배치

fillPage(), fillCol(), fillRow()
