30 pmPositionpmFragmentLengthAccess the fragment length for PM probes.DescriptionAccessor to the fragment length for PM probes.UsagepmFragmentLength(object, enzyme, type=c(snp, cn))ArgumentsobjectenzymetypePDInfo or SnpFeatureSet object.Enzyme to be used for query. If missing, all enzymes are used.Type of probes to be used: ’snp’ for SNP probes; ’cn’ for Copy Number probes.ValueNoteA list of length equal to the number of enzymes used for digestion. Each element of the list is adata.frame containing:• row: the row used to link to the PM matrix;• length: expected fragment length.There is not a 1:1 relationship between probes and expected fragment length. For one enzyme, agiven probe may be associated to multiple fragment lengths. Therefore, the number of rows in thedata.frame may not match the number of PM probes and the row column should be used to matchthe fragment length with the PM matrix.pmPositionAccessor to position informationDescriptionpmPosition will return the genomic position for the (PM) probes.UsagepmPosition(object)pmOffset(object)
