I am trying to debug a loop. Is there a way to print the value of a
variable
that is inside a loop? I have a vector v and inside a loop I have
v[i] where
i is the index of the loop. Is there a way to see v[i] per loop so
that I
can see what is going on?
Thanks

[1] 1
[1] 4
[1] 9
[1] 16
[1] 25

[1] "1 squared = 1"
[1] "2 squared = 4"
[1] "3 squared = 9"
[1] "4 squared = 16"
[1] "5 squared = 25"
