[R] For loop indicies

[Thomas Chesney]

Ah. I did a Silly Thing, and thank you for all the responses helping me track it down.

The issue lay not in the for (i in 1:C) but in the line VectorName[i] <- ...

That's the one that didn't like 0.

You may want to check how your loop "misses out" the zero:

C <- 5
for (i in 0:C) print(i)

## gives me

[1] 0
[1] 1
[1] 2
[1] 3
[1] 4
[1] 5

Enrico
