Damn powerful. Thank you again!

Hello Simon,
Mmmh you cannot have no selection made in radio buttons, one item must be selected.
What are you trying to achieve ?

I you want an 'unselected' state, maybe try this, it consists of putting an extra choice and hiding it while remaining selectable :
library(shiny)
library(shinyWidgets)
ui <- fluidPage(
tags$h1("Hidden radioGroupButtons"),
tags$br(),
radioGroupButtons(
inputId = "sent",
label = "Sentiment",
choiceValues = -2:3,
checkIcon = list(yes = icon("check")),
choiceNames = paste0(-2:3),
justified = TRUE, width = "300px"
),
tags$script("$(\"input:radio[name='sent'][value='3']\").parent().css('display', 'none');"),
verbatimTextOutput(outputId = "res"),
actionButton(inputId = "update", label = "Update")
)
server <- function(input, output, session) {
output$res <- renderPrint(input$sent)
observeEvent(input$update, {
updateRadioGroupButtons(session = session, inputId = "sent", selected = "3")
}, ignoreInit = TRUE)
}
shinyApp(ui, server)
With same JavaScript than last time ;)
