[R] when deleting a row from a matrix gives a vector

[Gabriel Valiente]

Deleting a row from a matrix turns it into a vector (and dim names  
are lost) if the resulting matrix has only one row or column. For  
instance:

 > x <- matrix(1:10, ncol=2)
 > x <- x[1,]

turns x into

[1] 1 6

instead of

      [,1] [,2]
[1,]    1    6

Is there any way to force the result to remain a matrix, even if it  
has only one row or column, or even only one entry? Thanks,

Gabriel
