annotate_intermut_dist_cohort: Annotate the intermutation distance of variants cohort-wide

Description Usage Arguments Value See Also Examples

Description

The function annotates the intermutational distance to a cohort wide data frame by applying annotate_intermut_dist_PID to every PID-specific subfraction of the cohort wide data. Note that annotate_intermut_dist_PID calls rainfallTransform. If the PID information is missing, annotate_intermut_dist_PID is called directly for the whole input.

annotate_intermut_dist_cohort(in_dat, in_CHROM.field = "CHROM",
  in_POS.field = "POS", in_PID.field = NULL, in_mode = "min",
  in_verbose = FALSE)

Arguments

in_dat

VRanges object, VRangesList, data frame or list of data frames which carries (at least) one column for the chromosome and one column for the position. Optionally, a column to specify the PID can be provided.

in_CHROM.field

String indicating which column of in_df carries the chromosome information

in_POS.field

String indicating which column of in_df carries the position information

in_PID.field

String indicating which column of in_df carries the PID information

in_mode

String passed through annotate_intermut_dist_PID to rainfallTransform indicating which method to choose for the computation of the intermutational distance.

in_verbose

Whether verbose or not.

Value

VRanges object, VRangesList, data frame or list of data frames identical to in_df (reordered by in_PID.field), but with the intermutation distance annotated as an additional column on the right named dist.
