IBD: Constructor function for objects of class 'IBD'
In CrypticIBDcheck: Identifying Cryptic Relatedness in Genetic Association Studies

Description Usage Arguments Details Value Author(s) See Also

Constructor function for objects of class IBD, used as both the input and output of the IBDcheck function. This is not intended to be called by users. Users preparing data for a call to IBDcheck should use the wrapper function new.IBD, which provides basic checks of the input.

`snp.data`	A snp.matrix object containing the genotypes. Rows correspond to subjects and columns correspond to SNPs.
`snp.support`	a data frame of SNP information
`subject.support`	a data frame of subject information
`ibd.study`	A data frame of estimated IBD coefficients for study subjects. Columns represent estimated probabilities of 0, 1 and 2 alleles IBD. Rows represent pairs of subjects.
`ibd.ur`	data frame of estimated IBD coefficients for simulated unrelated subjects
`ibd.mz`	data frame of estimated IBD coefficients for simulated monozygotic twins
`ibd.po`	data frame of estimated IBD coefficients for simulated parent-offspring subjects
`ibd.fs`	data frame of estimated IBD coefficients for simulated full sibling subjects
`ibd.hs`	data frame of estimated IBD coefficients for simulated half sibling subjects
`ibd.co`	data frame of estimated IBD coefficients for simulated cousins
`ibd.user`	data frame of estimated IBD coefficients for subjects having a user-defined relationship
`filterparams`	a list of data filtering options returned by `filter.control`
`simparams`	a list of data simulation options returned by `sim.control`
`call`	the `IBDcheck` call that created the `ibd.*` data frames
