在 R 中组合数据框的类别

Question

我是 R 的新手并且我在下面有以下数据框，y 轴上有 living_arrangements 顶点，x 轴上有 loneliness_level 顶点。

如果我想将 Alternate between parents and partner 和 College or student accomodation 合并到一个名为 other 的独特类别中，那么最好的方法是什么，这样我的数据框就会像下面这样？

                                    loneliness_level
living_arrangements       1 2 3 4 5 6 7 8 9 10
Alone                     1 1 0 2 0 1 1 3 1 4
Other                     1 2 5 2 2 1 2 3 1 0

Answer 1

如果我们想得到总和，使用rowsum

out <- rowsum(m1, group = c(1, 2, 2))
row.names(out) <- c("Alone", "Other")
names(dimnames(out)) <- names(dimnames(m1))

-输出

> out
                   loneliness_level
living_arrangements 1 2 3 4 5 6 7 8 9 10
              Alone 1 1 0 2 0 1 1 3 1  4
              Other 1 2 5 2 2 1 2 3 1  0

数据

m1 <- structure(c(1, 0, 1, 1, 0, 2, 0, 1, 4, 2, 0, 2, 0, 0, 2, 1, 0, 
1, 1, 0, 2, 3, 0, 3, 1, 0, 1, 4, 0, 0), .Dim = c(3L, 10L), .Dimnames = list(
    living_arrangements = c("Alone", "Alternate between parents and partner", 
    "College or student accomodation"), loneliness_level = c("1", 
    "2", "3", "4", "5", "6", "7", "8", "9", "10")))
