计算观察和考虑条件
我有一个这样的数据库:
id <- c(rep(1,3), rep(2, 3), rep(3, 3))
condition <- c(0, 0, 1, 0, 0, 1, 1, 1, 0)
time_point1 <- c(1, 1, NA)
time_point2 <- c(NA, 1, NA)
time_point3 <- c(NA, NA, NA)
time_point4 <- c(1, NA, NA, 1, NA, NA, NA, NA, 1)
data <- data.frame(id, condition, time_point1, time_point2, time_point3, time_point4)
data
id condition time_point1 time_point2 time_point3 time_point4
1 1 0 1 NA NA 1
2 1 0 1 1 NA NA
3 1 1 NA NA NA NA
4 2 0 1 NA NA 1
5 2 0 1 1 NA NA
6 2 1 NA NA NA NA
7 3 1 1 NA NA NA
8 3 1 1 1 NA NA
9 3 0 NA NA NA 1
我想制作一个表格,其中有多少个条件== 1(n_x),每个时间点(n_t)中有多少个。如果我也没有一个0。我尝试了这一点:
data %>%
pivot_longer(cols = contains("time_point")) %>%
filter (!is.na(value)) %>%
group_by(name) %>%
mutate(n_t = n_distinct(id)) %>%
ungroup() %>%
filter(condition == 1) %>%
group_by(name) %>%
summarise(n_x = n_distinct(id), n_t = first(n_t))
获得此问题:
name n_x n_t
<chr> <int> <int>
1 time_point1 1 3
2 time_point2 1 3
所需的结果:我想要这种类型的表格,以情况和没有状态来考虑案件:
name n_x n_t
1 time_point1 2 6
2 time_point2 1 3
3 time_point3 0 0
4 time_point4 0 3
谢谢!
I have a database like this:
id <- c(rep(1,3), rep(2, 3), rep(3, 3))
condition <- c(0, 0, 1, 0, 0, 1, 1, 1, 0)
time_point1 <- c(1, 1, NA)
time_point2 <- c(NA, 1, NA)
time_point3 <- c(NA, NA, NA)
time_point4 <- c(1, NA, NA, 1, NA, NA, NA, NA, 1)
data <- data.frame(id, condition, time_point1, time_point2, time_point3, time_point4)
data
id condition time_point1 time_point2 time_point3 time_point4
1 1 0 1 NA NA 1
2 1 0 1 1 NA NA
3 1 1 NA NA NA NA
4 2 0 1 NA NA 1
5 2 0 1 1 NA NA
6 2 1 NA NA NA NA
7 3 1 1 NA NA NA
8 3 1 1 1 NA NA
9 3 0 NA NA NA 1
I want to make a table with how many have the condition == 1 (n_x) and also how many are in each time point (n_t). In case there is none also I want a 0. I tried this:
data %>%
pivot_longer(cols = contains("time_point")) %>%
filter (!is.na(value)) %>%
group_by(name) %>%
mutate(n_t = n_distinct(id)) %>%
ungroup() %>%
filter(condition == 1) %>%
group_by(name) %>%
summarise(n_x = n_distinct(id), n_t = first(n_t))
Obtaining this:
name n_x n_t
<chr> <int> <int>
1 time_point1 1 3
2 time_point2 1 3
Desired Outcome: I want this type of table that considers the cases with condition and without it:
name n_x n_t
1 time_point1 2 6
2 time_point2 1 3
3 time_point3 0 0
4 time_point4 0 3

您可以
pivot_longer()
能够group_by()
time_points,然后总结一下添加值。对于条件,仅列values!= Na
的总和值。输出:
You can
pivot_longer()
to be able togroup_by()
time_points and then summarise just adding up the values. For conditions only sum values where the columnvalues != NA
.Output:
