Jupyter网页版笔记（操作R语言的dplyr包清洗数据）

2017-01-13 10:21 375 查看

这是我的第一个Jupyter网页版笔记

主要是介绍dplyr包清洗asreml中oats的数据

导入dplyr包

library(dplyr)


Attaching package: 'dplyr'

The following objects are masked from 'package:stats':

filter, lag

The following objects are masked from 'package:base':

intersect, setdiff, setequal, union


导入asreml包

library(asreml)


Loading required package: lattice

Licensed to: VSNC
Serial Number: 402567950 Expires: 28-feb-2017 (46 days)


导入数据

data(oats)


head(oats)

1 0_cwt 4 Marvellous1 105
1 0_cwt 1 Victory 2 111
1 0.2_cwt 2 Victory 2 130

选择一部分数据：用filter函数

选择Blocks=1和Variety=“Marvellous”

filter(oats,Blocks==1,Variety=="Marvellous")

1 0.4_cwt 2 Marvellous1 118
1 0.2_cwt 3 Marvellous1 140
1 0_cwt 4 Marvellous1 105

选择Blocks==1和Blocks==2

filter(oats,Blocks==1|Blocks==2)

排序，用arrange函数

按照oats的顺序进行排序

arrange(oats)
