Unable to clear the displayed output in ShinyApp using actionButton
I'm building a shinyApp on mtcars data. I got 2 actionButtons (Go & Clear).
The Go button is for displaying the output on mainPanel whereas the Clear button is for clearing that output.
My Clear button isn't working due to some unforeseen reason. Can somebody please have a look at my codes. I shall be extremely grateful.
library(shiny)
library(DT)
library(dplyr)
library(shinythemes)
library(htmlwidgets)
library(shinyWidgets)
library(shinydashboard)
data_table<-mtcars
#ui
ui = fluidPage(
sidebarLayout(
sidebarPanel (
uiOutput("cyl_selector"),
uiOutput("disp_selector"),
actionButton(inputId = "go", label = "Go"),
actionButton(inputId = "reset", label = "Clear")),
mainPanel(
DT::dataTableOutput('mytable') )))
#server
server = function(input, output, session) {
output$cyl_selector <- renderUI({
selectInput(inputId = "cyl",
label = "cyl:", multiple = TRUE,
choices = c( unique(as.character(data_table$cyl))),
selected = c('4')) })
output$disp_selector <- renderUI({
available <- data_table[c(data_table$cyl %in% input$cyl ), "disp"]
selectInput(
inputId = "disp",
label = "disp:",
multiple = TRUE,
choices = c('All',as.character(unique(available))),
selected = 'All') })
thedata <- eventReactive(input$go,{
data_table<-data_table[data_table$cyl %in% input$cyl,]
if(input$disp != 'All'){
data_table<-data_table[data_table$disp %in% input$disp,]
}
data_table
})
# thedata <- eventReactive(input$reset,{
# data_table<-NULL
# })
output$mytable = DT::renderDataTable({
DT::datatable( filter = "top", rownames = FALSE, escape = FALSE,
options = list(pageLength = 50, autowidth=FALSE,
dom = 'Brtip' ),
{
thedata() # Call reactive thedata()
})
})}

I didn't analyze your script completly, but i can see that it doesn't call the second button at all (Clear). You made an eventReactive() using input$go for the first button to make the plot, but you need to call input$reset too if you want to make it work.
