[R] Multi t tests

[Imri]

hi all

I have R object look like this:
> spl
$SB012XSB044
    DPW       Cross
1  66.6 SB012XSB044
2  96.5 SB012XSB044
3  78.8 SB012XSB044
4  68.6 SB012XSB044
5  62.0 SB012XSB044
6  72.1 SB044XSB012
7  72.2 SB044XSB012
8  69.6 SB044XSB012
9  87.9 SB044XSB012
10 84.4 SB044XSB012
11 51.9 SB044XSB012
12 65.5 SB044XSB012

$SB012XSB099
     DPW       Cross
13 100.9 SB012XSB099
14  44.4 SB012XSB099
15  83.5 SB012XSB099
16  89.9 SB012XSB099
17  78.0 SB012XSB099
18  83.0 SB012XSB099
19 114.3 SB099XSB012
20 173.1 SB099XSB012
21 114.3 SB099XSB012
22  58.8 SB099XSB012
23  98.1 SB099XSB012
24  12.8 SB099XSB012

I want to do a t test for DPW values by the 2 different Cross types for each
of spl components. 
Any suggestions? I just got errors till now

Thanks,
Imri.
