Dear all, Could you please explain me why
> OverloadsTesT [1] 1 0 1 0 0 0 0 0 0 0 > a<-matrix(data=seq(1,10),nrow=10) > a [,1] [1,] 1 [2,] 2 [3,] 3 [4,] 4 [5,] 5 [6,] 6 [7,] 7 [8,] 8 [9,] 9 [10,] 10 > a[-OverloadsTesT] [1] 2 3 4 5 6 7 8 9 10 the last line does not remove the first and third element and only does the first element.? What I want to do is for zeros to return the elements and for any positive value to remove it. What I am doing wrong?
