[BioC] contrast matrix syntax error

[Simon Melov]

Hi,
I am trying to make some contrasts in limma. I keep getting a syntax  
error. My design is read in ok, as well as everything else upto making  
a contrast matrix.

design
    4day 9day 14day 19day 14daf 19daf 4daf 9daf control
1    -1    0     0     0     0     0    0    0       0
2    -1    0     0     0     0     0    0    0       0
3    -1    0     0     0     0     0    0    0       0
4    -1    0     0     0     0     0    0    0       0
5     0   -1     0     0     0     0    0    0       0
6     0   -1     0     0     0     0    0    0       0
7     0   -1     0     0     0     0    0    0       0

....42 arrays.

contrast.matrix <-  
makeContrasts(4day,9day,14day,19day,14daf,19daf,4daf,9daf,control,4day 
-19day,levels=design)
Error: syntax error

What am I doing wrong?

thanks

Simon.
