Hello limma users/developers, Are missing values imputed in limma, and if so, which imputing method is used? Thank you. -------- Yiwen He, Ph.D., M.P.H.

I assume you are asking how lmFit() handles missing values. It does not impute. Missing values are treated the same as in lm() with na.action=na.omit. See ?lm
