HapMap (or Wellcome INBREDS) -based metadata structures for SNPs
Objects can be created by calls of the form new("snpMeta", ...)
.
meta
:"environment"
holds the table in
the meta
element,
in the form of a data.frame
, with rownames giving the SNP ids,
and columns pos
, strand
chromosome
:"character"
string
identifying chromosome on which SNPs are documented signature(x = "snpMeta")
: select subset using rs numbersignature(x = "snpMeta")
: obtain chromosome name signature(x = "snpMeta")
: obtain named vector of positions signature(from = "snpMeta", to = "data.frame")
: return
data.frame with all metadata signature(x = "snpMeta")
: give dimensions signature(x = "snpMeta")
: tell number of entries signature(object = "snpMeta")
: give abbreviated report of contents
with exemplar recordsVJ Carey <stvjc@channing.harvard.edu>
