如何命名列表元素

Question

我创建了一个列表，我想命名列表的元素。有人可以帮我吗？

LL <- vector(mode = "list")

L11 <- seq(1, 10)
L12 <- seq(11, 20)
LL[[length(LL)+1]] <- cbind(L11, L12)   
# I want to name LL[[1]] as "L1", but this does not work
names(LL[[length(LL)]]) <- c("L1")

L21 <- seq(21, 30)
L22 <- seq(31, 40)
LL[[length(LL)+1]] <- cbind(L21, L22)
# I want to name LL[[2]] as "L2", but this does not work
names(LL[[length(LL)]]) <- c("L2")

LL

Answer 1

这应该有效

LL <- vector(mode = "list") 
LL$l1 <- seq(1, 10)
LL$l2 <- seq(11, 20)

Answer 2

根据David Arenburg（见上面的评论）：

names(LL)[1L] <- "L1"
