[R] matrix building with two variables

[Schmitt, Corinna]

Dear R-Experts,

I have two variables coming from my calculations:

Tissues --> WT sun41 Revertante 
NullPoint --> 0.826 0.871 0.859

Now I want to build a matrix, where row1=Tissues and row2=NullPoint is.
How can I realize this?

Thanks, Corinna
