probe_to_385k: Finds nearest probe on hg18_385k

In arnijohnsen/arjtools: Collection of tools used in copy number variation analysis

Description

Returns nearest probe on a 385k array design in hg18 assembly

Usage

probe_to_385k(x, chrom)

Arguments

x	Numeric vector, with genomic coordinate of probe
chrom	Character or character vector (in the form "chr11", "chrX", etc.), with chromosome of probe. All elements must be identical.

Value

Numeric vector, with genomic coordinate of closest probe in the hg18_385k design

Examples

  # Create sample data
  library(data.table)
  dat <- data.table(chrom = c("chr1", "chr1"), pos = c(46348, 46349))
  dat[, pos_385k := map_to_385k(pos, chrom), by = chrom]
  dat
