Oubox Boxes above MainPanel Table in RShiny

#1

Suppose I have a numeric column named 'Sales' in a Dataframe. There are 1000 rows (Suppose). And values range from 50$ to say 3500$.

My Rshiny app has 2 sections. SideBar layout and MainPanel. Main Panel has this Dataframe as a Table. I am calculating the mean and variance of this Sales column and want to show it in separate boxes above the main panel table. Is there any reference code for such an UI setup ? Please help

You would just need to add on top of the table output within mainPanel, something like this (I used the skimr package for displaying the table stats.

library(shiny)
library(tidyverse)
library(DT)
#> 
#> Attaching package: 'DT'
#> The following objects are masked from 'package:shiny':
#> 
#>     dataTableOutput, renderDataTable
library(skimr)

sales_vec = round(runif(1000,min = 50, max = 3500))
my_tibble = tibble(Var = 1:1000, Sales = sales_vec)

ui <- fluidPage(
  sidebarLayout(sidebarPanel = sidebarPanel(
    selectInput("select_nothing", "This does nothing", choices = LETTERS[1:10])
  ),
  mainPanel = mainPanel(
    h4('Table Stats'),
    DT::dataTableOutput("my_summary"),
    br(),
    br(),
    h4('Table View'),
    DT::dataTableOutput("my_table")
  ))
)

server <- function(input, output, session) {
  output$my_table = renderDT({
    datatable(my_tibble)
  })
  
  output$my_summary = renderDT({
    datatable(skim(my_tibble), options = list(dom = "t"))
  })
  
}

shinyApp(ui, server)
