WebSplit vector in R. Suppose you have a named vector, where the name of each element corresponds to the group the element belongs. Hence, you can split the vector in two vectors where the elements are of the same group, passing the names of the vector with the names function to the argument f.. a <- c(x = 3, y = 5, x = 1, x = 4, y = 3) a WebSplit data frame by groups. Source: R/group-split.R. group_split () works like base::split () but: It uses the grouping structure from group_by () and therefore is subject to the data mask. It does not name the elements of the list based on the grouping as this only works well for a single character grouping variable. incentive\u0027s my https://twistedunicornllc.com
