R 如何在我的字符串中命名东西？

我是R的新手，所以我对基础知识有点困惑。目前，我有一个使用以下代码创建的字符串：

coldf <- character (length=2500)

看起来您正在使用

rep（）

函数。它有三个基本用法：

通过多次将向量连接到自身来重复向量

通过多次重复每个元素来重复向量

通过将不同元素重复不同次数来重复向量

举例说明：

x = letters[1:5]
# 1
rep(x, 4)
# [1] "a" "b" "c" "d" "e" "a" "b" "c" "d" "e" "a" "b" "c" "d" "e" "a" "b" "c" "d" "e"
# 2
rep(x, each = 4)
# [1] "a" "a" "a" "a" "b" "b" "b" "b" "c" "c" "c" "c" "d" "d" "d" "d" "e" "e" "e" "e"
# 3
rep(x, 5:1)
# [1] "a" "a" "a" "a" "a" "b" "b" "b" "b" "c" "c" "c" "d" "d" "e"

@是的！非常感谢。

rep（c（“苹果”、“香蕉”、“梨”），每个=50）

@onyanbu谢谢你的帮助

x = letters[1:5]
# 1
rep(x, 4)
# [1] "a" "b" "c" "d" "e" "a" "b" "c" "d" "e" "a" "b" "c" "d" "e" "a" "b" "c" "d" "e"
# 2
rep(x, each = 4)
# [1] "a" "a" "a" "a" "b" "b" "b" "b" "c" "c" "c" "c" "d" "d" "d" "d" "e" "e" "e" "e"
# 3
rep(x, 5:1)
# [1] "a" "a" "a" "a" "a" "b" "b" "b" "b" "c" "c" "c" "d" "d" "e"
