Server render function for info value

Usage

render_info_value(
  expr,
  env = parent.frame(),
  quoted = FALSE,
  sep = " ",
  add_name = TRUE
)

Arguments

expr: value to render
env: The environment in which to evaluate expr. Default parent.frame()
quoted: Is expr a quoted expression (with quote())? This is useful if you want to save an expression in a variable. Default FALSE
sep: A separator passed to cat to be appended after each element.
add_name: Should expression name be added. Default TRUE

Value

Shiny render function to be saved as an element of output.

Details

If you want to use it with toggle_info(), you have to add outputOptions(output, [info value id], suspendWhenHidden = FALSE) to force rendering when the value is hidden.

Examples

if(interactive()) {
library(shiny)
library(shiny.info)

ui <- fluidPage(
  info_value("value_to_display")
)

server <- function(input, output, session) {
  test_reactive <- reactiveVal("some value")
  output$value_to_display <- render_info_value(expr = test_reactive())
  # next line is required to work with toggle_info()
  outputOptions(output, "value_to_display", suspendWhenHidden = FALSE)
}
}
