我需要根据DimentionID对此数据集的行进行排序，此列中的所有值最后都具有年龄组类别，例如1_8到25岁以下，1_25到35岁以下，等等。我要订购这些年龄类别的行。 例如：最后所有具有18至小于25岁的值，然后所有具有25至小于35岁的值，等等。
答案 0 :(得分：0)
您可以使用正则表达式：
使用a作为您的data.frame：
matches <- regexpr('[[:alpha:]]{4} than [[:digit:]]{2}',a$DimentionID)
content <- substr(a$DimentionID, matches, matches + attr(matches, 'match.length'))
content向量现在应包含与排序相关的部分字符串。
剩下的就是用它来创建索引向量并用它对data.frame进行排序：
a[order(content),]
答案 1 :(得分：0)
这是一种方法：
library(dplyr)
dim_grouped %>%
mutate(age_g = gsub('[0-9]+_', '', DimentionID)) %>%
arrange(age_g)
