我很想知道闪亮的反应性。我想使用selectInput来选择行的名称,并让表只显示该行,然后显示几列。
例如,如果我的行是人(" Anna"," Tim"," Larry"),我的列是变量(" A& #34;," B"," C")我希望selectInput显示" Anna"和数据表只显示Anna的变量A,B和C.
我坚持如何做到这一点。
ui <- shinyUI(
fluidPage(
fluidRow(
column(2, selectInput("name", "Select a Name:",
c("Anna"= "smith.anna",
"Tim" = "miller.tim"))),
column(6, "People Table", tableOutput("mytable")
))))
server <- function(input, output) {
output$mytable <- renderTable({
mydataset[mydataset, input$name]})
}
我很确定我的服务器功能搞砸了,但所有提示都很有帮助!谢谢!

查看我的评论:
mydataset <- data.frame(A = 1:3, B = 4:6, C = 7:9)
row.names(mydataset) <- c("smith.anna", "miller.tim", "page.larry")
ui <- shinyUI(
fluidPage(
fluidRow(
column(2, selectInput("name", "Select a Name:",
c("Anna"= "smith.anna",
"Tim" = "miller.tim"))),
column(6, "People Table", tableOutput("mytable")
))))
server <- function(input, output) {
output$mytable <- renderTable({
mydataset[input$name, ]
})
}
shinyApp(ui, server)
