[R] how to show a section of a matrix neatly (or row by row) that satisfies some condition

[Edmond Ng]

Hi all, 

I want to show the rows of a matrix (100x3) of which some of its elements satisfy a certain condition. In particular, how can I display the 2 rows of my matrix one after the 
other and not all all elements of column 1 first, then column 2 and so on. See the following. 

> finest[finest[,1] > 10^3] 
[1] 4.960632e+13 3.612619e+04 7.668204e+12 1.001911e+04 8.886153e-01
[6] 6.130777e-01

> dim(finest) 
[1] 100   3


Many thanks in advance.
