我想知道为什么rownames()
在我的下面的R代码中无法正常工作?
revenue = c(15,18,22,23,24, 22,25,15,15,14, 18,22,15,19,21,
23,15,14,17,18, 23,15,26,18,14, 12,15,11,10,8, 26,12,23,15,18,
19,17,15,20,10, 15,14,18,19,20, 14,18,10,12,23, 14,22,19,17,11,
21,23,11,18,14)
months = gl(12, 5)
years = gl(5, 1, length(revenue))
m = matrix(c(revenue, years, months), nrow = 60, ncol = 3)
rownames(m) = list(paste0("subj ", 1:60)) ### Why rownames() doesn't work? ###
答案 0 :(得分:1)
因为您使用list
,但rownames
接受了一个向量。请改用:
rownames(m) = paste0("subj ", 1:60)

我的偏好是让R的本质为你工作,因为它会迭代粘贴并分配名称。
row.names(m) <- paste0("subj " , 1:60)
它调用最少的函数并完成工作,
