我无法在R闪亮中使用标签$ operator。对于任何标签，我收到错误：
$：$运算符对原子矢量无效
以下是示例应用
server <- function(input, output, session) {
}
ui <- basicPage(
h1("Title without tags$"),
tags$blockquote("But block quote requires tags$ because it is less common than h3, h1 or code"),
h3("H3 is fine without tags and so is code here"),
code("data.frame(a=1:10, b=1:10)")
)
shinyApp(ui = ui, server = server)
以下是错误明细

我收到任何标记$运算符的相同错误。我是R的新人。请让我知道我错过了什么？
