Html R：如何在数据框中嵌入sliderInputs/selectInputs和单选按钮？（错误：无法将类“shinny.tag”强制为data.frame）

我需要在矩阵中嵌入不同类型的输入。对于textInput（）和NumericiInput（），它可以正常工作，但是我找不到一种方法来处理selectInput（）、sliderInput（）和radioButton（）

我可以用HTML指定textInput和NumericiInput，比如

paste0("<input id='num", 1:2, "' class='shiny-bound-input' type='text' value=''>")

我得到的错误是：无法将类“shinny.tag”强制为data.frame。所以我推断我应该在HTML->中指定它们，有人知道怎么做吗

下面是代码（您可以看到下面的图片）：

ui=pageWithSidebar(
headerPanel（“测试”），
侧栏面板(
helpText（'某些类型的输入可以包含在矩阵中，而某些类型的输入不能'）
),
主面板(
uiOutput（'matrix_text'），
uiOutput（'matrix_num'），
uiOutput（“矩阵_滑块”），
uiOutput（'matrix_select'），
uiOutput（“矩阵\单选按钮”）
)
)
服务器=功能（输入、输出）{
输出$matrix_text我找到了解决方案。对于ex的单选按钮，代码为：

paste0("<div class='control-group shiny-input-radiogroup shiny-bound-input' id='radio",1:2,"'>
    <label class='control-label' for=='radio",1:2,"'>Individual</label>
    <label class='radio'>
    <input id=='radio1",1:2,"' name='radio",1:2,"' type='radio' value='cyl'>
    <span>Cylinders</span>
    </label>
    <label class='radio'>
    <input id=='radio2",1:2,"' name='radio",1:2,"' type='radio' value='am'>
    <span>Transmission</span>
    </label>
    </div>")

paste0（“
个人
圆筒
传输
")

可通过右键单击带有单选按钮的网页并选择“检查元素”来获取

希望这能帮助其他人
