[BioC] EdgeR error message when using plotSmear (missing values)

[anna [guest]]

Dear all, at which step should I change my parameters to avoid this error message ? 
> detags <- rownames(y)[as.logical(de)]
> plotSmear(lrt, de.tags=detags)
Erreur dans quantile.default(M, c(0.05, 0.95)) : 
  missing values and NaN's not allowed if 'na.rm' is FALSE

thanks,
anna
