在 R 中粘贴 header 和前 2 行并换行

Question

我有 3 行

first <- LETTERS[1:9]
second <- c(1:9)
third <- letters[1:9]
> first
[1] "A" "B" "C" "D" "E" "F" "G" "H" "I"
> second
[1] 1 2 3 4 5 6 7 8 9
> third
[1] "a" "b" "c" "d" "e" "f" "g" "h" "i"

我想要带有换行的 9 个元素的输出向量

"A    "B
 1     2
 a"    b"  and so on

我尝试使用循环，但它不起作用

y <-c()
z <-c()

 for(i in 1:length(first)){
  y <- paste(first, second, sep = "\n")
  z <- paste(y, third, sep = "\n")
}

我出来了

[1] "A\n1\na" "B\n2\nb" "C\n3\nc" "D\n4\nd"
[5] "E\n5\ne" "F\n6\nf" "G\n7\ng" "H\n8\nh"
[9] "I\n9\ni"

这不是给我一个换行符。我的报告的 colnames(data) 格式需要像那样。感谢您的提前。

我对你的理解是否正确，你正在寻找这个：

first <- LETTERS[1:9]
second <- c(1:9)
third <- letters[1:9]

cat(c(first, "\n", second, "\n", third))

A B C D E F G H I 
1 2 3 4 5 6 7 8 9 
a b c d e f g h i

?
