按row.name子集矩阵

我有一个具有以下行名的矩阵：

"X1"   "X5"   "X33"  "X37"  "X52"  "X566"

现在我只想选择与列表条目匹配的行，比如：

include_list <- c("X1", "X5", "X33")

include_list设置一些假数据：

m <- matrix(1:30, 6, 5)
rownames(m) <- c("X1", "X5", "X33", "X37", "X52", "X566")
m
#      [,1] [,2] [,3] [,4] [,5]
# X1      1    7   13   19   25
# X5      2    8   14   20   26
# X33     3    9   15   21   27
# X37     4   10   16   22   28
# X52     5   11   17   23   29
# X566    6   12   18   24   30

使用
subset（）
函数替代：

subset(m, rownames(m) %in% include_list)
#      [,1] [,2] [,3] [,4] [,5]
# X1     1    7   13   19   25
# X5     2    8   14   20   26
# X33    3    9   15   21   27

这似乎也可行：

include_list <- head(read.csv("/Users/histelheim/include_list.csv", header = FALSE))
include_list <- c(do.call("cbind", include_list)) 
data[row.names(data) %in% include_list, ]

include_list以防万一某人的include_list是classlist（而不是vector），那么这是对Rich Scriven的答案的修改，在这种情况下，该修改基于<应添加代码>取消列表（）
：

m <- matrix(1:30, 6, 5)
rownames(m) <- c("X1", "X5", "X33", "X37", "X52", "X566")
include_list <- list("X1", "X5", "X33")


m[unlist(include_list), ]

m
include_list <- head(read.csv("/Users/histelheim/include_list.csv", header = FALSE))
include_list <- c(do.call("cbind", include_list)) 
data[row.names(data) %in% include_list, ]

m <- matrix(1:30, 6, 5)
rownames(m) <- c("X1", "X5", "X33", "X37", "X52", "X566")
include_list <- list("X1", "X5", "X33")


m[unlist(include_list), ]
