How to check if a set is a subset of another set in R?
To check if a set is a subset of another set, we can use all function with %in% operator. For example, if we have two vectors say x and y and we want to check whether x is a subset of y then we can use the command given below −
all(x %in% y)
Check out the below given examples to understand how it works.
Example 1
To check if a set is a subset of another set in R, use the snippet given below −
set_x1<-rpois(100,2) set_x1
If you execute the above given snippet, it generates the following output −
[1] 5 4 2 3 1 2 2 1 3 0 1 4 2 0 4 3 2 0 1 2 2 3 1 3 2 3 1 1 2 3 1 4 0 4 2 0 0 [38] 2 1 5 2 3 1 1 1 0 0 2 1 2 1 0 2 0 0 2 0 2 1 0 2 4 5 2 1 3 3 1 3 1 1 5 3 3 [75] 5 3 3 4 3 2 3 2 1 1 0 3 1 2 3 3 0 2 1 2 3 4 3 1 2 5
To check if a set is a subset of another set in R, use the snippet given below −
set_y1<-rpois(100,5) set_y1
If you execute the above given snippet, it generates the following output −
[1] 3 3 2 5 6 11 8 6 8 6 4 5 9 4 4 3 5 5 6 6 7 4 7 5 12 [26] 4 2 8 6 9 8 6 5 6 2 7 5 5 13 3 3 5 5 6 5 4 7 2 7 8 [51] 9 5 9 1 6 7 4 4 5 3 7 8 4 6 4 6 6 5 4 5 4 2 4 5 6 [76] 5 4 7 3 5 6 8 4 9 5 8 2 2 7 6 5 1 3 5 4 9 15 12 6 6
To check if a set is a subset of another set in R, add the following code to the above snippet −
all(set_x1 %in% set_y1)
Output
If you execute all the above given codes as a single program, it generates the following output −
[1] FALSE
Example 2
To check if a set is a subset of another set in R, use the snippet given below −
set_x2<-sample(0:9,200,replace=TRUE) set_x2
