I have a dataset with the following layout (random example):
set.seed(1)
data <- tibble(A = sample(c(TRUE, FALSE), 10, replace = T), B = sample(c(TRUE, FALSE), 10, replace = T), C = sample(c(TRUE, FALSE), 10, replace = T), value = sample(1:100, 10))
For each combination of A, B and C I want to calculate the mean(value). Ideally, I want a new tidy tibble with these combinations of A, B and C and the result (including A, AB, ABC, AC, etc - all possible combinations of A/B/C if).
Here, rows 1,3 and 4 are all ABC which would result in
ABC - mean(89, 79, 33)
For row 2,5 B,C - mean(44,84)
How would I go about this?
CodePudding user response:
A simple solution is to use dplyr: group_by the variables A, B, C, then summarise the mean of the values:
library(dplyr)
dat2<-dat%>%
group_by(A,B,C)%>%
summarise(Mean = mean(value))
