I have two vectors of different lenghts. How can I start both series so their ends concide.
x<-c(1,2,3,4,5,6,7,8,9,10,11,12,1,2,3,4,5,6)
y<-c(1,2,3,4,5,6,7,8,9,10,11,12,1,2,3,4)
I do it with the code below but I guess there must be a more elegant way
x<-x[((length(x)-length(y))+1):length(x)]
x
[1] 3 4 5 6 7 8 9 10 11 12 1 2 3 4 5 6
y
[1] 1 2 3 4 5 6 7 8 9 10 11 12 1 2 3 4
Use tail
, and min
to determine the shortest vector:
shortest <- min(length(x), length(y))
y <- tail(y, shortest)
x <- tail(x, shortest)
