传递动态输入并更新R SHINY中的视觉 [英] Passing dynamic input and updating visual in R shiny

问题描述

下面的脚本在执行时会创建一个带有SELECT输入的process_map()。在选择"r1"、"r2"等资源时，我们会得到相应的流程图。然而，我希望动态地传递来自选择栏的输入，并更新R Siny页面Snapshot for your reference中的流程图。请帮帮忙。

## app.R ##
install.packages("bupaR")
install.packages("edeaR")
install.packages("eventdataR")
install.packages("processmapR")
install.packages("processmonitR")
install.packages("xesreadR")
install.packages("petrinetR")
install.packages("shiny")
install.packages("shinydashboard")
library(shiny)
library(shinydashboard)
library(bupaR)
library(edeaR)
library(eventdataR)
library(processmapR)
library(processmonitR)
library(xesreadR)
library(petrinetR)
ui <- dashboardPage(
dashboardHeader(),
dashboardSidebar(

selectInput("resources","Select the resource", c("r1","r2","r3","r4","r5"), 
selected = "r1",selectize = T)
),
dashboardBody(
filter_resource(patients,resources = c("r1","r2","r4"), reverse = F) %>% 
process_map()
))
server <- function(input, output) { 
}
shinyApp(ui, server)

推荐答案

您可以

library(shiny)
library(shinydashboard)
library(bupaR)
library(edeaR)
library(eventdataR)
library(processmapR)
library(processmonitR)
library(xesreadR)
library(petrinetR)
ui <- dashboardPage(
dashboardHeader(),
dashboardSidebar(

selectInput("resources","Select the resource", c("r1","r2","r3","r4","r5"),selected = "r1",selectize = T)
),
dashboardBody(
  uiOutput("ui")
))
server <- function(input, output) { 
  output$ui <- renderUI({
    r <- input$resources
    tagList(filter_resource(patients,resources = r, reverse = F) %>% process_map())
  })
}
shinyApp(ui, server)
