如何使用group_by和summarise汇总所有列? [英] How to summarise all columns using group_by and summarise?
问题描述
我正在整理我的日常活动数据(加速度计数据).我想总结所有列每一天的重复行.我有32行(有些重复)和90列(一个主题的数据).
I'm trying to tidy my daily activity data (accelerometer data). I would like to sum the repeated rows of each day for all columns. I have 32 rows (some are repeated) and 90 columns (data of one subject).

我尝试了一些小代码,但是,几乎所有方法都失败了.下面的代码是我可以获得的,它太大了.我想知道是否还有其他方法可以使它更小.
I have tried some small codes, but, I have failed in almost all. The code below is what I could get, it's too big. I'm wondering if have any other way to do it smaller.
# LbNr = subjects' id
# Weekday = 1 Monday.... 7 Sunday
# Type = activities: A1. NonWorking, A2. Working, A4. SleepWeek, C0. Leisure, C4. SleepWeekend
# code
df %>% select(LbNr, Type, Weekday, Time, lie:IncTrunkWalk) %>%
group_by(LbNr, Type, Weekday) %>%
summarise(n = n(), Time = sum(Time),lie = sum(lie), sit = sum(sit), stand = sum(stand),
move = sum(move), walk = sum(walk), run = sum(run), stairs = sum(stairs),
cycle = sum(cycle), row = sum(row), WalkSlow = sum(WalkSlow),
WalkFast = sum(WalkFast)) %>%
arrange(Weekday) %>% filter(Weekday %in% c('3':'7'))
到目前为止,我对这段代码还有另一个问题.我的问题是在星期六"6",当我连接时,时间可能是星期六收到从星期五开始的活动(请参见下面的示例),有时会出现"A1.不工作"或"A4.SleepWeek",具体取决于志愿者.我想总结一下有关"C0.休闲"的另一项活动.如果可能的话,我想用一个代码完成.
So far I had another problem with this code. My problem is on Saturday "6", when I concatenate the time could be that Saturday receives activities that started on Friday (see the example below), sometimes will appear "A1. NonWorking" or "A4. SleepWeek", depends on the volunteer. I would like to sum this different activity on "C0. Leisure". If it was possible I would like to do it in one code.
# LbNr Type Weekday n Time lie sit
# <dbl> <fct> <dbl> <int> <dbl> <dbl> <dbl>
#8 22002 A2. Working 5 1 11.0 0.0103 6.77
#9 22002 A4. SleepWeek 5 1 6.42 5.49 0.930
#10 22002 A1. NonWorking 6 1 0.433 0.0169 0.302
#11 22002 C0. Leisure 6 1 15.7 0.245 9.78
#12 22002 C4. SleepWeekend 6 1 7.9 6.96 0.922
#13 22002 C0. Leisure 7 2 15.6 0.122 12.0
#I would like to get something like this.
# LbNr Type Weekday n Time lie sit
# <dbl> <fct> <dbl> <int> <dbl> <dbl> <dbl>
#8 22002 A2. Working 5 1 11.0 0.0103 6.77
#9 22002 A4. SleepWeek 5 1 6.42 5.49 0.930
#10 22002 C0. Leisure 6 1 16.133 0.2619 10.082
#11 22002 C4. SleepWeekend 6 1 7.9 6.96 0.922
#12 22002 C0. Leisure 7 2 15.6 0.122 12.0
对于第一个问题,我希望得到一个小的代码.而且,如果可能的话,我希望对星期六的各种活动进行汇总可以获得更好的代码.
For the first problem, I expect to get a small code. Moreover, if it was possible, I would expect to get a better code for the sum of different activities on Saturday.
预先感谢,路易斯
推荐答案
如果没有更好的示例,很难尝试回答您的问题(即,您可以 dput()
您的数据来给我们一个样本).但是,这是您上一个问题的解决方案:对于第一个问题,我希望得到一个包含所有列重复行的总和的表.此外,如果可能的话,我希望得到一个更好的总和代码周六的不同活动."
It's hard to try and answer your question without a better example (ie, you can dput()
your data to give us a sample). But here is a solution to your last issue: "For the first problem, I expect to get a table with the sum of repeated rows for all columns. Moreover, if it was possible, I would expect to get a better code for the sum of different activities on Saturday."
# create toy data of 3 different IDs, 3 different types, and repeated days
df <- data.frame(id=sample(c(1:3),100,T),
type=sample(letters[1:3],100,T),
day=sample(c(1:7),100,T),
matrix(runif(300),nrow=100),
stringsAsFactors = F)
# gather data, summarize each activity column by ID, type and day
# and select Saturday==6
df %>% gather(k,v,-id,-type,-day) %>%
group_by(id,type,day,k) %>%
summarise(sum=sum(v)) %>%
filter(day==6) %>%
spread(k,sum)
# A tibble: 8 x 6
# Groups: id, type, day [8]
id type day X1 X2 X3
<int> <chr> <int> <dbl> <dbl> <dbl>
1 1 a 6 1.85 3.26 2.09
2 1 b 6 0.604 0.583 0.586
3 1 c 6 0.163 0.663 0.624
4 2 a 6 0.185 0.952 0.349
5 2 b 6 1.16 0.832 0.974
6 2 c 6 0.906 1.62 0.853
7 3 b 6 0.671 1.39 0.887
8 3 c 6 0.449 0.150 0.647
更新
这是提供了新数据的更新解决方案.

我认为这回答了您有关想要小代码"的第一个问题.我仍然不明白您的第二个问题,即我希望对星期六的各种活动进行总结能得出更好的代码".这是否意味着您只想汇总星期六的不同活动(躺,坐等)?还是要汇总不同类型的活动(A2,C0等)?
I think this answers your first question about wanting a 'small code'. I don't understand your second question still about "I would expect to get a better code for the sum of different activities on Saturday." Does this mean that you want to sum across the different activities (lie, sit, etc.) for Saturday only? Or do you want to sum across different types (A2, C0, etc) of activities?
