由 ﹥＞﹥吖頭↗ 提交于 2020-07-23 06:54:25
问题 I'm trying to populate dynamically generated tabs with plots made from a loop but can't get the tabs to populate with all of the plots generated in the loop. shinyUI(pageWithSidebar( headerPanel("Dynamic number of plots"), sidebarPanel( ), mainPanel( # This is the dynamic UI for the plots uiOutput("IndividualPlots") ) )) server <- function(input, output) { output$IndividualPlots <- renderUI({ if (is.null(input$data_cqt0)) { return() } plot_content() shiny:::buildTabset( id = "t", lapply(1

Pass reactives to flexdashboard

由 夙愿已清 提交于 2020-06-17 08:16:13
问题 I have a large Shiny app, and I would like to provide the possibility to export a flexdashboard report. Thus, I added a downloadHandler which passes certain params to the flexdashboard. The flexdashboard itself should work without being deployed on a server, thus I do not use the runtime: shiny option. How can I pass reactive values to the flexdashboard? If I do something like params <- list(y = test()) , the report creation breaks. Relevant part of server.R: test <- reactive({ [[SOME STUFF]]

Create shiny app with sankey diagram that reacts to selectinput

由 喜夏-厌秋 提交于 2020-06-01 03:16:14
问题 I'm trying to create a dashboard with a Sankey diagram and a selectInput that lets the end user choose filter the source column. I'm having trouble trying to figure out how to use the reactive expressions to filter the data. It's sort of complex because it's not just one step of reading the data in as it has to be preprocessed. I've tried putting the reactive filter at the end but it isn't working, as you'll see below. I tried also making each step reactive but that was a mess that certainly

Reactive Spring Query Parameters

由 …衆ロ難τιáo~ 提交于 2020-05-12 05:01:48
问题 My Spring Reactive Web API should be able to filter based on query parameters but I'm struggling to get this right. GET /v1/address?type=business Should return all addresses of type 'business' in the system (just an example since I'm not posting the actual requirements). If the parameter is absent then just return all addresses. [ { "id" : 1, "type" : "business", "street" : "..."}, { "id" : 2, "type" : "business", "street" : "..."}, ... } I'm using Router functions to map the request: public

快速比较 Kafka 与 Message Queue 的区别

https://hackernoon.com/a-super-quick-comparison-between-kafka-and-message-queues-e69742d855a8 A super quick comparison between Kafka and Message Queues Hendrik Swanepoel Follow Jun 10, 2017 This article’s aim is to give you a very quick overview of how Kafka relates to queues, and why you would consider using it instead. Kafka is a piece of technology originally developed by the folks at Linkedin. In a nutshell, it’s sort of like a message queueing system with a few twists that enable it to support pub/sub, scaling out over many servers, and replaying of messages. These are all concerns when

vue3.0实战从0到1实战电商管理系统（第二天）

章节文章课程简介： 任何事情都需要时间的沉淀，技术也不例外，今天编写Vue3.0系列的章节文章，只是希望能够比别人更早的去尝鲜一些新的技术，毕竟Vue3.0已经Beta版本了，所以里正式版本也不远了，提前去学习和了解，我们就会比别人有更多的时间去充分理解Vue3.0的特性，只有当你真正理解一门技术的时候，才能够正确的判定它是否合适、是否应该运用到你当前的实际项目当中去。 第一天：浅谈vue3.0、初始化项目之：Hello World Vue3.0 第二天：Api实战之：vue-composition 我是api调用工程师 第三天：vue3如何实现逻辑复用 第四天：实战之：高解耦式mock api的设计与订单列表查询 第五天：如何实现代码优化 今天是第二天：Api实战之：vue-composition 我是api调用工程师 学习任何框架之前，首先肯定要学习的是它的生命周期，Vue3.0的所有生命周期函数都是在setup函数中定义，具体包含生命周期机器定义如下： import { onBeforeMount, onMounted, onBeforeUpdate, onUpdated, onBeforeUnmount, onUnmounted, onErrorCaptured, onRenderTracked, onRenderTriggered, } from "vue" ;
