查询用R编写代码的更好方法 [英] Inquiring a better way to write code in R

问题描述

我是R的新手，我想寻求帮助，以找到一种更好的方式来编写下面编写的代码.任何帮助，将不胜感激.

I am new to R, and I'd like help in finding a better way to write the following code I've written. Any help would be appreciated.

df$rank[between(df$score,0,1.2)] <- 1
df$rank[between(df$score,1.2,2.1)] <- 2
df$rank[between(df$score,2.1,2.9)] <- 3
df$rank[between(df$score,2.9,3.7)] <- 4
df$rank[between(df$score,3.7,4.5)] <- 5
df$rank[between(df$score,4.5,5.4)] <- 6

推荐答案

您可以使用cut:

df$rank <- cut(x = df$score,c(0,1.2,2.1,2.9,3.7,4.5,5.4,Inf),FALSE)
