<font size="3D2" face="3DArial"><o:p> </o:p></font>
<font size="3D2" face="3DArial">I’ve just started using = ”R” with the bioconductor-packages. I’m = now trying to analyse our cDNA-array data.<o:p></o:p></font>
<font size="3D2" face="3DArial">Using the function “read.Spot” I’ve managed to import my data from a tab separated file. After = this, I’ve used the normalization function “maNormMain(mbatch=3DTOR493, f.loc=3Dlist(maNormLoess(x=3D"maA", y=3D"maM", z=3DNULL, w=3DNULL, subset=3DTRUE, span=3D0.4)), = f.scale=3DNULL, a.loc=3DmaCompNormEq(), a.scale=3DmaCompNormEq(), echo=3DFALSE)”.<o:p></o:p></font>
<font size="3D2" face="3DArial"><o:p> </o:p></font>
<font size="3D2" face="3DArial">So far everything seems to be fine, but when I try to visualize my results with “maDiagnPlots1(mraw=3DTOR493, title=3DNULL, = save=3DFALSE)”,<o:p></o:p></font>
<font size="3D2" face="3DArial">I get an error message “Error in rep(NA, maNspots(L)) : invalid number of copies in "rep"”. I don’t understand this error message. = What could be wrong?<o:p></o:p></font>
<font size="3D2" face="3DArial"><o:p> </o:p></font>
<font size="3D2" face="3DArial">I’d appreciate if someone who has more = experience than me could give me any suggestions.<o:p></o:p></font>
