Title: Help I don't want to get fillpeaks
Post by: truyenhinhanvien on April 15, 2015, 06:58:45 PM
Hi,
I would like to process my data but not using fillpeaks. Hereafter is the return I got:

> reporttab<-diffreport(xset2,"échantillons","pools","urines_par_ech",10,metlin=0.15,h=480,w=640)
Erreur dans .local(object, ...) : NA values in xcmsSet. Use fillPeaks()
any idea how to circumvent this problem and to get to the reporttab step?

many thanks

anvien

Hi anvien,

diffreport() uses Student's t test for the statistics, which in turn
does not allow NA values.

If you want a table and not use filleaks(), check out peakTable()

Yours,
Steffen
