R 使用多个唯一标识符扩展我的数据帧

我正在尝试创建一个数据帧，该数据帧通过以下方式传播我的数据帧：

我的数据1我们可以更广泛地使用pivot\u

使用base R，您可以执行以下操作：

reshape(my_data1, v.names = "deformity", timevar = "name", dir="wide", idvar = "Tank", sep="_")

  Tank Bag deformity_ally deformity_nancy deformity_ted deformity_mark
1   1A  C1         spinal            <NA>        spinal           <NA>
