[R] Help to make a for for index

[Ronaldo Reis Jr.]

Hi,

I try to make a vector in a for for loop, but it dont work.

Look:

> a <- 0;for(i in c(1:2)) { for(j in c(1:2)) { a <- i+j; print(a)}}
[1] 2
[1] 3
[1] 3
[1] 4

I try to make this a vector, like this:
[1] 2 3 3 4

> a <- 0;for(i in c(1:2)) { for(j in c(1:2)) { a[j] <- i+j}}; print(a)
[1] 3 4
> a <- 0;for(i in c(1:2)) { for(j in c(1:2)) { a[i] <- i+j}}; print(a)
[1] 3 4

In this way the vector have only the two last loop.

I try another way but it dont work.

How make a correct index for this loop inside loop?

Thanks
Ronaldo
