Hi,

I am using Limma to get differential expressed genes between case and
control samples. In addition, I want to adjust the "weight" of patients by
including it in the "design" matrix. However, one weight value of a patient
is missing, so I have a "NA" in design matrix. When I run lmFit, I got the
error message :Error in qr.default(x) : NA/NaN/Inf in foreign function call
(arg 1).

Can limma handle the missing value in design matrix or I have to remove
this sample ?

Thanks,

Chen
