[R] Matrix elements

[Akkineni,Vasundhara]

Hello all,

I have a matrix object, xx given as below:

             [,1]         [,2]
 [1,]  0.02237883  0.601572660
 [2,] -0.39880918  0.126498958
 [3,]  0.20269214  0.567953402
 [4,] -0.45750812 -0.031193600
 [5,] -0.30666134 -0.084819484
 [6,] -0.37718928  0.078675868
 [7,] -0.25432685 -0.005200316
 [8,] -0.22146224  0.168196438
 [9,] -0.32049919 -0.013216047
[10,]  0.94325749  1.341664313

How can i check for every row in the matrix that both the column elements are greater than zero, and if they are greater than zero then to print the row number. I tried using for loops, but it kept returning warnings. Please let me know how this can be done.

Thanks,
Vasu.
