How to use "for loop" to get couples of indexes every time in R?

Question

Let's assume I have this vector v:

v = seq(1,30,1)

I write this simple loop:

for(i in v) {
  print(i)
}

However, I would like to write a loop that gives me, in time, 1:2, 3:4, 5:6, 7:8, etc. I would then get:

[1] 1,2
[1] 3,4
[1] 5,6
[1] 7,8
...

Can anyone help me?

Thanks!

Answer 1

Maybe you can generate v with step of 2.

v = seq(1,30,2)
for(i in v) {
  cat(paste(i, i + 1, sep = ','), '
')
}

#1,2 
#3,4 
#5,6 
#7,8 
#9,10 
#11,12 
#13,14
