从R中的列表内的变量名中删除后缀 [英] removing suffixes from variable names inside a list in R

问题描述

使用BASE R，我想知道如何从下面G的变量(例如short..3变为short)中删除..number后缀?

Using BASE R, I was wondering how I can remove ..number suffixes from variables (e.g., short..3 becomes short) in G below?

G <- list(AA = list(short..3 = data.frame(dint = 5:7, SD = 0:2), 
                    short..2 = NULL, 
                    del1 = data.frame(dint = 1:3, SD = 2:4), 
                    del1..2 = NULL, del2 = NULL), 
          BB = list(short = data.frame(dint = 1:4, SD = 2:5), 
                    short..2 = NULL, 
                    del1..4 = data.frame(dint = 5:6, SD = 3:4), 
                    del1..2 = NULL, 
                    del2 = data.frame(dint = 6, SD = 1)))

推荐答案

for (i in seq_along(G)) {
  names(G[[i]]) <- gsub("(.*)\\.\\.\\d*", "\\1", names(G[[i]]))
}

OR

lapply(G, function(i) setNames(i, gsub("(.*)\\.\\.\\d*", "\\1", names(i))))
