I am trying to understand the reactive part in R shiny. In that process I am trying to update an output table based on the input change while selecting values from the age drop down. It seems to do it by the first value but when I change any value from the age drop down it wont update my table . The input I am using is
chooseage
. Below is the code which I am using.
library(shiny)
library(shinydashboard)
library(shinyBS)
library(knitr)
library(kableExtra)
library(shiny)
library(shinythemes)
ui <- dashboardPage(
dashboardHeader(disable = F, title = "Study"),
dashboardSidebar(sidebarMenu(
menuItem(
"Population Filter",
uiOutput("choose_age")
)
)),
dashboardBody(box(
width = 12,
tabBox(
width = 12,
id = "tabBox_next_previous",
tabPanel("Initiation",
fluidRow(
box(
width = 5,
solidHeader = TRUE,
status = "primary",
tableOutput("smoke"),
collapsible = F
)
))
),
uiOutput("Next_Previous")
))
)
server <- function(input, output, session) {
# Drop-down selection box for which Age bracket to be selected
output$choose_age <- renderUI({
selectInput("selected_age", "Age", as.list(levels(with_demo_vars$age)))
})
myData <- reactive({
with_demo_vars %>%
filter(age == input$choose_age) %>%
pct_ever_user(type = "SM")
})
output$smoke <-
renderTable({
head(myData())
})
}
shinyApp(ui = ui, server = server)
