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 > sessionInfo() R version 2.9.1 (2009-06-26) i386-pc-mingw32 locale: LC_COLLATE=English_India.1252;LC_CTYPE=English_India.1252;LC_MONETARY= English_India.1252;LC_NUMERIC=C;LC_TIME=English_India.1252 attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] limma_2.18.3 affy_1.22.1 Biobase_2.4.1 GLAD_2.0.0 DNAcopy_1.18.0 loaded via a namespace (and not attached): [1] affyio_1.12.0 preprocessCore_1.6.0 tools_2.9.1 The information contained in this electronic message and in any attachments to this message is confidential, legally privileged and intended only for use by the person or entity to which this electronic message is addressed.

Somewhat unlikely that you will get much help using an R 2.9.1 -- please upgrade to 2.14.1, install with biocLite, and try again.
