如何根据 R 中一列的值对该表进行子集/拆分? [英] How do I subset/split this table bases on the values of one column in R?

问题描述

数据可以在这里找到:https://www.dropbox.com/s/l7pc11hhiwr8zzn/data.csv?dl=0 ，或者在图书馆 MASS 中作为 nlschools .

The data can be found here: https://www.dropbox.com/s/l7pc11hhiwr8zzn/data.csv?dl=0 , or else as nlschools in the library MASS.

我想根据 nlschools$SES 的值拆分此表，将表拆分为 nlschools$SES 为 <=30 的表，<代码>30 和 >40，并保留所有列.

I'd like to split this table based on the value of nlschools$SES, having the table divide into tables where nlschools$SES is <=30, 30 < SES <= 40 and > 40, and with all the columns remaining.

我尝试过使用带有 0:30 之类的间隔的 cut，但结果非常混乱，并且没有剩余的完整列集.

I have tried using cut with intervals like 0:30, but the result is very confusing and does not have the complete set of columns remaining.

我希望我要实现的目标描述得足够清楚.

I hope what I'm trying to achieve is described clear enough.

推荐答案

尝试:

one<-subset(nlschools, nlschools$SES <=30)
two<-subset(nlschools, nlschools$SES >30 &  nlschools$SES<=40)
three<-subset(nlschools, nlschools$SES >40)
