You cannot specify the lower and upper cut off lines. They are specified by
the SAM algorithm based on your choice of delta. So if you wanna change the
lower and upper cut off lines you have to change delta. See, e.g.,


for an explanation how the lower and upper cutoff are computed for a
specified delta.

> Hello everybody,
> I am using the siggenes package.
> I have a data set of 45101 genes across 4 experiments.
> I wanted to perform a two class paired SAM analysis with the data.
> My data is stored in the form of a 45101*4 matrix(B) and the class 
> vector is like 0,0,1,1(B.cl).
> I have used the following commands to plot my data..

> to the sam function.
> So the plot showed all genes marked in green.
> Can anybody please  help me ASAP?
> Thanks and Regards,
