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
