## Class "snpMeta" – HapMap (or Wellcome INBREDS) -based metadata structures for SNPs

### Description

HapMap (or Wellcome INBREDS) -based metadata structures for SNPs

### Objects from the Class

Objects can be created by calls of the form `new("snpMeta", ...)`.

### Slots

`meta`:
  Object of class `"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`:
  Object of class `"character"` string identifying chromosome on which SNPs are documented

### Methods

[
  `signature(x = "snpMeta")`: ...
chromosome
  `signature(x = "snpMeta")`: ...
coerce
  `signature(from = "snpMeta", to = "data.frame")`: ...
dim
  `signature(x = "snpMeta")`: ...
nrow
  `signature(x = "snpMeta")`: ...
show
  `signature(object = "snpMeta")`: ...
