UI 中的 *Output 函数 R对象变为ui输出的函数: Output_function /Creates dataTableOutput DataTable htmlOutput raw HTML imageOutput image plotOutput plot tableOutput table textOutput text uiOutput raw HTML verbatimTextOutput text 添加方式和添加html元素及组件一样,放到 sidebarPanel or mainPanel in the ui. # 3. server中渲染函数 render function / creates renderDataTable DataTable renderImage images (saved as a link to a source file) renderPlot plots renderPrint any printed output renderTable data frame, matrix, other table like structures renderText character strings renderUI a Shiny tag object or HTML ####################################### # ref ####################################### 发现一个别人做的 https://github.com/szenitha/Shiny-Seq/tree/master/App # https://cloud.tencent.com/developer/article/1558051 好复杂,没看懂。
