[SOLVED] Need guidance to create value box output

Need guidance to create value box output

I'm creating a shiny app with local persistent data referred from Dean Attali blog as in section: 1. Local file system (local).

My query is, is it possible to create value box output from this method?

aggregates data from inputs

formData <- reactive({
  formdata <- c("Associate Name" = input$aname,"Associate Email"=input$aemail,"Client Name" = input$cname,
            "Client Email"=input$cemail,"Ask By Customer"=input$ask,"Remarks"=input$rem ,
            "Date" = as.character(input$date), "Followup Date" = as.character(input$fdate))

  formdata <- t(formdata)
  formdata
})

saves data to csv (this creates a separate file every time we submit)

saveData <- function(formdata) {
   fileName <- sprintf("%s_%s.csv",
                       humanTime(),
                       digest::digest(formdata))

   write.csv(x = formdata, file = file.path(responsesDir, fileName),
             row.names = FALSE, quote = TRUE)
}

loads the data (Binding all csv's which contains responses)

Data <- reactive( {
  # Read all the files into a list
  files <- list.files(responsesDir, full.names = TRUE)
  data <- lapply(files, read.csv, stringsAsFactors = FALSE)
  # Concatenate all data together into one data.frame
  data <- do.call(rbind, data)
  data <- data.frame(data)
  data
}

displaying data in a table

output$responses <- DT::renderDataTable({
input$submit
Data()
})

I would like to know if we could create valueBoxOutput to display number of times an Associate name is recorded, number of times a client name has been recorded

E.g: someClient - 10, someAssociate - 5

This is my first shiny app, please help me through this. Thanks in advance!!

Solution

I figured it how to do it. the trick is in how we using the reactive function.

 output$billing <- renderValueBox({
    valueBox(value = length(Data()$Billing[Data()$Billing =="Yes"]),
             subtitle = "No. of RFP's billed", color = "green",icon=icon("money",lib = "font-awesome"))

  })
