ggplot2：将标签添加到geom_bar（）进行计数

Question

我正在尝试在我的条形图中添加计数标签，该条形图是我们研究中男性和女性人数的简单频率图表。我试过+ stat_count（）并收到错误-错误：stat_count需要以下缺失的美感：x。我也尝试过+ geom_label（stat =“ count”）。似乎没有任何作用。我可以使用excel轻松做到这一点，但我想使用R来完成所有绘图。

有人对此有一个简单的解决方案吗？

我的代码：

{
    "type": "message",
    "id": "1485983408511",
    "timestamp": "2017-02-01T21:10:07.437Z",
    "localTimestamp": "2017-02-01T14:10:07.437-07:00",

    },
    "textFormat": "plain",
    "text": "Hello Teams TestBot",
    "entities": [
      { 
        "locale": "en-US",
        "country": "US",
        "platform": "Windows",
        "timezone": "America/Los_Angeles",
        "type": "clientInfo"
      }
    ],
    "channelData": {
        "tenant": {
            "id": "72f988bf-86f1-41af-91ab-2d7cd011db47"
        }
    }
}

它产生以下内容： My plot without bar labels
