问题
I would like to make a simple table with
dplyr
and
summarise
But I can't really figure out how ... (Even though it should be quite simple).
I have a matrix of sequences. When I simply tabulate
table(dta)
I have the result I want.
dta
acquaintance alone child notnotnot nuclear
1 2 17 19 131
nuclear and acquaintance nuclear and acquaintance nuclear and acquaintance nuclear and acquaintance partner
1 1 1 35 2
However, I can't figure out how to do the same with summarise
Any suggestion ?
dta = structure(c("nuclear", "nuclear", "child", "child", "child",
"acquaintance", "nuclear and acquaintance", "nuclear and acquaintance",
"notnotnot", "nuclear", "nuclear", "nuclear", "child", "child",

You just have to convert your data to a data.frame to use dplyr and then you can easily get your desired output:
require(dplyr)
# ungrouped
data_frame(var = c(dta)) %>%
group_by_("var") %>%
summarise(n())
## var n()
## 1 acquaintance 1
## 2 alone 2
## 3 child 17
## 4 notnotnot 19
## 5 nuclear 131
## 6 nuclear and acquaintance 1
## 7 nuclear and acquaintance 1
## 8 nuclear and acquaintance 1
## 9 nuclear and acquaintance 35
## 10 partner 2
If you want to do this for each column seperately, you can use tidyr to first gather the result and then spread it again.
require(tidyr)
# grouped
dta %>%
as.data.frame %>%
gather %>%
group_by(key, value) %>%
summarise(N = n()) %>%
spread(key, N)
## value 12:10 12:20 12:30 12:40 12:50 13:00 13:10 13:20 13:30 13:40 13:50 14:00 14:10
## 1 acquaintance 1 NA NA NA NA NA NA NA NA NA NA NA NA
## 2 alone NA 1 NA NA NA NA NA NA NA NA NA NA NA
## 3 child 3 3 4 3 2 NA NA NA NA NA NA NA NA
## 4 notnotnot 1 1 1 1 1 1 1 1 1 1 1 NA NA
## 5 nuclear 3 3 3 4 5 7 7 7 7 7 7 7 7
## 6 nuclear and acquaintance NA NA NA NA NA NA NA NA NA NA NA NA NA
## 7 nuclear and acquaintance NA NA NA NA NA NA NA NA NA NA NA NA NA
## 8 nuclear and acquaintance NA NA NA NA NA NA NA NA NA NA NA NA NA
## 9 nuclear and acquaintance 2 2 2 2 2 2 2 2 2 2 2 2 2
## 10 partner NA NA NA NA NA NA NA NA NA NA NA 1 1
## Variables not shown: 14:20 (int), 14:30 (int), 14:40 (int), 14:50 (int), 15:00 (int), 15:10 (int), 15:20 (int),
## 15:30 (int)
