[R] Write vector/matrix in a loop

[kokavolchkov]

Hello!

I'm trying to *save values* (*row and col*) in two matrices(1,m) or vectors.
I have a loop, where a get these values:

for(i in 144){
	for(j in 73){
		if(B4[i,j]==1){ # B4 is a matrix(73, 144)
			row <- B4[i-(i-1),j] 
			col <- B4[i,j-(j-1)] 
		}
	}
}

*How to save row and col?*

Thank you!
