Dear All,
I am trying to use the DNAcopy package to perform CBS segmentation on my copy number data. As given in the manual, i have created my CNA.object by reading a file for chromosome, position and values for one sample. When performing smoothed.CNA.object <- smooth.CNA(CNA.object) I get  the following error:
> smoothed.CNA.object <- smooth.CNA(CNA.Object)
Error in if (xi > max(xnbhd) + oSD) xi <- median(c(xi, xnbhd)) + sSD :
  missing value where TRUE/FALSE needed
In addition: Warning message:
In max(xnbhd) : no non-missing arguments to max; returning -Inf

I will highly appreciate if someone can tell me where could i be possibly going wrong?

Thanks and Regards,
Ekta
