Web我们可以先对数据进行分组,然后使用 chull 函数计算出每组数据的凸点,再将每个分组的凸点合并为数据框. 注意:我们应该先对数据进行拆分,因为 chull 函数返回的是点的索引,对数据 group_by 之后,索引是基于每个分组而不是整个数据而言的,切记。 WebThe slice function of the dplyr R package can be used to extract columns of a data frame or tibble as shown below: slice ( data, c (1, 3, 5)) # Apply slice function # x1 x2 x3 # 1 1 A 5 # 2 3 C 5 # 3 5 E 5. Within the slice function, we had to specify the name of our input data and the row index of all rows we want to retain.
