How to remove the first replicate in a vector using another vector that contains similar elements in R?
To remove the first replicate in a vector using another vector, we can use match function. For example, if we have a vector x that contain values 0, 1, 2, 3, 4, 5 and 0, 1, 2 are repeated in another vector say then the removal of this replicate will result in values 3, 4, and 5. This can be done by using x[-match(y,x)].
Example
x1<-0:5 x1
Output
[1] 0 1 2 3 4 5
Example
y1<-0:2 y1
Output
[1] 0 1 2
Example
x1[-match(y1,x1)]
Output
[1] 3 4 5
Example
x2<-sample(0:5,120,replace=TRUE) x2
Output
[1] 0 3 3 4 3 0 4 2 1 3 0 2 0 1 3 1 5 2 3 1 1 2 5 2 0 0 3 1 3 0 3 0 0 0 3 2 4 [38] 0 0 2 5 5 0 1 3 1 2 5 5 2 2 4 1 5 3 3 3 4 1 4 0 1 4 1 3 3 4 0 1 1 0 3 1 4 [75] 5 2 5 1 3 4 3 3 1 3 3 2 1 2 3 4 0 1 1 5 4 0 4 1 3 0 0 0 2 1 3 2 4 5 2 5 3 [112] 5 0 4 5 4 1 0 0 2
Example
y2<-sample(0:2,120,replace=TRUE) y2
Output
[1] 2 1 1 1 0 0 1 1 1 0 1 0 0 1 2 2 1 0 2 0 0 1 2 1 0 2 1 0 2 0 2 0 2 2 2 0 1 [38] 2 2 0 0 0 1 2 2 1 2 1 2 2 1 0 1 0 0 1 2 1 0 2 2 2 0 0 0 2 0 0 1 2 0 2 1 2 [75] 1 2 1 2 1 2 1 2 2 0 1 2 1 2 0 0 0 0 0 0 1 1 2 1 1 0 0 2 2 1 2 0 1 0 2 0 0 [112] 2 0 2 0 0 2 0 1 1
Example
x2[-match(y2,x2)]
Output
