Shiny updateRadioButtons

I'd like to use upateRadioButtons in order to clear all the RadioButtons input selections. My shiny app uses several RadioButtons as input, but only the first one is cleared when using updateRadioButtons. All other RadioButtons remain at their last selection. 

UpdateInputs <- function(data, session) {
  updateRadioButtons(session, "var1", 
                     choices = list("zero" = 0, "one" = 1, "two" = 2, "three" = 3, "four" = 4), 
                     selected = character(0), inline=T)
  updateRadioButtons(session, "var2", 
                     choices = list("zero" = 0, "one" = 1, "two" = 2, "three" = 3, "four" = 4,    
  selected = character(0), inline=T)
}

I found the following solution: replacing 

selected = character(0)

by 

selected = ""

does the trick.
