Jupyter网页版笔记（操作R语言的dplyr包清洗数据）

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

导入数据

data(oats)

head(oats)

Blocks	Nitrogen	Subplots	Variety	Wplots	yield
1	0.6_cwt	1	Marvellous	1	156
1	0.4_cwt	2	Marvellous	1	118
1	0.2_cwt	3	Marvellous	1	140
1	0_cwt	4	Marvellous	1	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")

Blocks	Nitrogen	Subplots	Variety	Wplots	yield
1	0.6_cwt	1	Marvellous	1	156
1	0.4_cwt	2	Marvellous	1	118
1	0.2_cwt	3	Marvellous	1	140
1	0_cwt	4	Marvellous	1	105

选择Blocks==1和Blocks==2

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

Blocks	Nitrogen	Subplots	Variety	Wplots	yield
1	0.6_cwt	1	Marvellous	1	156
1	0.4_cwt	2	Marvellous	1	118
1	0.2_cwt	3	Marvellous	1	140
1	0_cwt	4	Marvellous	1	105
1	0_cwt	1	Victory	2	111
1	0.2_cwt	2	Victory	2	130
1	0.6_cwt	3	Victory	2	174
1	0.4_cwt	4	Victory	2	157
1	0_cwt	1	Golden_rain	3	117
1	0.2_cwt	2	Golden_rain	3	114
1	0.4_cwt	3	Golden_rain	3	161
1	0.6_cwt	4	Golden_rain	3	141
2	0.4_cwt	1	Marvellous	1	104
2	0_cwt	2	Marvellous	1	70
2	0.2_cwt	3	Marvellous	1	89
2	0.6_cwt	4	Marvellous	1	117
2	0.6_cwt	1	Victory	2	122
2	0_cwt	2	Victory	2	74
2	0.2_cwt	3	Victory	2	89
2	0.4_cwt	4	Victory	2	81
2	0.2_cwt	1	Golden_rain	3	103
2	0_cwt	2	Golden_rain	3	64
2	0.4_cwt	3	Golden_rain	3	132
2	0.6_cwt	4	Golden_rain	3	133

排序，用arrange函数

按照oats的顺序进行排序

arrange(oats)

Blocks	Nitrogen	Subplots	Variety	Wplots	yield
1	0.6_cwt	1	Marvellous	1	156
1	0.4_cwt	2	Marvellous	1	118

根据Blocks倒序，其它正序

arrange(oats,desc(Blocks))
