Call Variable from reactive data() in R Shiny App

Question

I would like to call a certain variable within a reactive expression. Something like this:

server.R

library(raster)

shinyServer(fun         


        

Answer 1

Reactives are just like other functions in R. You can't do this:

f <- function() {
  x <- 1
  y <- 2
}

f()$x

So what you're within output$Plot() won't work either. You can do what you want by returning a list from data().

data <- reactive({

  inFile <- input$test 
  asc <- raster(inFile$datapath) 
  list(asc_new1 = 1/asc, asc_new2 = asc * 100)

}) 

Now you can do:

data()$asc_new1
