Passing a list of arguments into a function in R Shiny
Use do.call
do.call("dropdown", c(box_params,
label = "Plot Options Box 1",
numericInput(inputId = "box1",
label = "Value", min = 1, max = 5, value = 3)))
full code:
library(shiny)
library(shinydashboard)
library(shinyWidgets)
box_params <- list(icon = icon("cogs"),
width = "400px")
ui <- dashboardPage(
dashboardHeader(),
dashboardSidebar(),
dashboardBody(
box(title = "Box 1",
dropdownMenu = do.call("dropdown", c(box_params, list(label = "Plot Options Box 1",
numericInput(inputId = "box1", label = "Value", min = 1, max = 5, value = 3))))
),
box(title = "Box 2",
dropdownMenu = do.call("dropdown", c(box_params, list(label = "Plot Options Box 2",
numericInput(inputId = "box2", label = "Value", min = 1, max = 5, value = 3))))
)
)
)
server <- function(input, output) { }
shinyApp(ui, server)
output:
I will delete this: but If i do:
library(shiny)
library(shinydashboard)
library(shinyWidgets)
box_params <- list(icon = icon("cogs"),
width = "400px")
ui <- dashboardPage(
dashboardHeader(),
dashboardSidebar(),
dashboardBody(
box(title = "Box 1",
dropdownMenu = dropdown(box_params,
label = "Plot Options Box 1",
numericInput(inputId = "box1", label = "Value", min = 1, max = 5, value = 3)
)
),
box(title = "Box 2",
dropdownMenu = dropdown(box_params,
label = "Plot Options Box 2",
numericInput(inputId = "box2", label = "Value", min = 1, max = 5, value = 3)
)
)
)
)
server <- function(input, output) { }
shinyApp(ui, server)
I get this:
So this is the same of @akrun's output?
Here is a version which actually renders the dropdown menu (The box()
function doesn't have a dropdownMenu
argument as @DJC's example code suggests):
library(shiny)
library(shinydashboard)
library(shinyWidgets)
box_params <- list(icon = icon("cogs"),
width = "400px")
ui <- dashboardPage(
dashboardHeader(),
dashboardSidebar(),
dashboardBody(
box(title = "Box 1",
do.call(dropdown, c(box_params,
list(label = "Plot Options Box 1",
numericInput(inputId = "box1", label = "Value", min = 1, max = 5, value = 3))))
),
box(title = "Box 2",
dropdown(
icon = icon("cogs"),
width = "400px",
label = "Plot Options Box 2",
numericInput(inputId = "box2", label = "Value", min = 1, max = 5, value = 3)
)
)
)
)
server <- function(input, output) {}
shinyApp(ui, server)
