r - shiny conditional panel not updating -


i have issue conditional panel. show in sidebarpanel either daterange or sliderinput depending on selected choice in radiobutton, in sidebarpanel.

if try run below example fail following error message:

error : formal argument "condition" matched multiple actual arguments

if comment out of 2 conditions can see example variable has value a or b depending on options chosen.

i'm pretty sure i'm missing something, cannot figure out what. did around , couldn't find helpful.

library(shiny)  # server ---------------------------------------------  server = shinyserver(function(input, output){   output$debug <- renderprint({     input$example   }) })   # ui -------------------------------------------------  ui = {   fluidpage(     sidebarpanel(       radiobuttons('example', 'select examples: ', choices = c('a', 'b'), selected = 'a'),       conditionalpanel(         condition = "input.example == 'a'",         daterangeinput('date', 'select date range:',                        start = sys.date() - 7,                        end = sys.date(),                        min = '2012-04-01',                        max = sys.date()                        )         ,         condition = "input.example == 'b'",         sliderinput('date', 'slide date range:', min = 1, max = 90, value = 14, step = 1)        )     ),     mainpanel(verbatimtextoutput("debug")     )   )}   # app ------------------------------------------------  shinyapp(ui = ui, server = server)

thanks

you need specify 2 conditionalpanel objects, 1 each condition.

library(shiny)  # server ---------------------------------------------  server = shinyserver(function(input, output){   output$debug <- renderprint({     input$example   }) })   # ui -------------------------------------------------  ui = {   fluidpage(     sidebarpanel(       radiobuttons('example', 'select examples: ', choices = c('a', 'b'),             selected = 'a'),     conditionalpanel(       condition = "input.example == 'a'",       daterangeinput('date', 'select date range:',                    start = sys.date() - 7,                    end = sys.date(),                    min = '2012-04-01',                    max = sys.date()     )   ),   conditionalpanel(     condition = "input.example = 'b'",     sliderinput('date', 'slide date range:', min = 1, max = 90, value = 14,            step = 1)   ) ), mainpanel(verbatimtextoutput("debug") ) )}   # app ------------------------------------------------  shinyapp(ui = ui, server = server)
