How to create the vector 2:10 and 10:2 using the seq function

Question

I need to use seq() to create the vector (2,3,4,5,6,7,8,9,10,9,8,7,6,5,4,3,2), but I'm stuck. I've done quite a bit of YouTube-ing and reading online, but can't find a specific enough solution.

Any help is appreciated, but please use the seq function when making recommendations.

Answer 1

Using seq function, you need to following two steps:

Step-1 Generate sequence from 2 to 10 using following code:

a<-seq(from=2,to = 10)

Step-2 Generate sequence from 10 to 2 using following code:

b<-seq(from=9,to = 2)

Now, combine above two results using following code:

data<-c(a,b)

The output should as follow:

> data
[1]  2  3  4  5  6  7  8  9 10  9  8  7  6  5  4  3  2 

Hope it works for you!
