Hi,

How do I ensure that I always get a matrix back when I extract rows?

The mickey-mouse example doesn't matter much, but if instead of 1:2 or
1, I have a vector which may have 1 or more values, then I'm in trouble.

Any way to make this consistently return a matrix?
Thx in advance.

> x <- matrix( 1:10, nrow = 5 )
> x
     [,1] [,2]
[1,]    1    6
[2,]    2    7
[3,]    3    8
[4,]    4    9
[5,]    5   10
> class( x[1:2,] )
[1] "matrix"			# this is good
> class( x[1,] )
[1] "integer"			# this is EVIL
