Hello, everyone, When I analyzed my microarray data set using marrayNorm package, I got following error massage: Error in simpleLoess(y, x, w, span, degree, parametric, drop.square, normalize, : invalid `x' However I could not find where the simpleLoess function is. What is the problem? anything wrong with my data? Thank you. Yihuan

Hi Yihuan, Can you send us the command you use?

Jean, Here is my command: faber.norm<-maNormMain(faber.raw, f.loc = list(maNormLoess(x="maA", y="maM", z=NULL, w=NULL, subset=FALSE, span=0.4)), f.scale=NULL, a.loc=maCompNormEq(), Mloc = TRUE, Mscale=TRUE, echo=FALSE) Thank you.

Hi Just to say I get this error message when my data has two many NA values in a particular print-tip area, or where too many of my data points are on the M = C * A line due to there being lots of divsion by 1.

You might find the function "maNorm" and maNormScale easier to use. To do print-tip loess data <- maNorm(faber.raw) global loess data <- maNorm(faber.raw, norm="l") Cheers Jean On Wed, 25 Feb 2004, Yihuan Xu wrote: > Jean, > > Here is my command: > > faber.norm<-maNormMain(faber.raw, f.loc = list(maNormLoess(x="maA", y="maM", > z=NULL, w=NULL, > subset=FALSE, span=0.4)), f.scale=NULL, a.loc=maCompNormEq(), Mloc = TRUE, > Mscale=TRUE, echo=FALSE) > > Thank you. > > Yihuan > > > > ----- Original Message ----- > From: "Jean Yee Hwa Yang" <jean@biostat.ucsf.edu> > To: "Yihuan Xu" <yihuan.xu@jefferson.edu> > Cc: <bioconductor@stat.math.ethz.ch> > Sent: Wednesday, February 25, 2004 12:31 PM > Subject: Re: [BioC] error when running marrayNorm > > > > Hi Yihuan, > > > > Can you send us the command you use? > > > > Jean > > > > On Wed, 25 Feb 2004, Yihuan Xu wrote: > > > > > Hello, everyone, > > > > > > When I analyzed my microarray data set using marrayNorm package, I got > > > following > > > error massage: > > > > > > Error in simpleLoess(y, x, w, span, degree, parametric, drop.square, > > > normalize, : > > > invalid `x' > > > > > > However I could not find where the simpleLoess function is.
