r - 是否可以按设备类型自动对用户代理进行分类？

Question

我从数据集中提取了一些用户代理指标，但我想知道是否有办法对这些指标进行分类。

具体来说，我想知道有多少用户正在使用：

• 移动的
• 桌面
• 药片

我当然可以手动检查其中一个指标 - 例如os.family- 并以这种方式对它们进行分类，但它效率不高，我想自动执行此操作。

除此之外，似乎没有办法确定设备是否是平板电脑（据我所知，没有特定于平板电脑的操作系统）；如果这不可能，那么我很乐意将其tablet归入该mobile类别，因为平板电脑确实是定义上的移动设备。

目前我正在使用这个uaparserjs包，因为它似乎做得比较好，除了缺乏分类。

有没有办法做到这一点？

如果它们被证明是我目前使用的更好的解决方案，我也愿意接受其他建议或建议。

以下是提取的用户代理数据的前 20 行：
