Group SNPs; adapted from group.multi by Chris Wallace

groupmulti( SM2, snp.data, is.snpmat, min.mppi = 0.01, minsnpmppi = 0.01, r2.minmerge = 0.5 )

`SM2` |
snpmod object |

`snp.data` |
SnpMatrix or SNP covariance matrix with snp ids as column names |

`is.snpmat` |
logical taking value TRUE when SnpMatrix is provided and FALSE when covariance matrix is given |

`min.mppi` |
trim snp groups with total MPPI < min.mppi in all diseases |

`minsnpmppi` |
only group snps with total MPPI > minsnpmppi |

`r2.minmerge` |
merge groups with minimum between-group r2 > r2.minmerge |

list with three components.

First is a data.frame with each row giving summary statistics for each group.

Second is a groups object, each elements ordered according to the rows of the summary

Third is the r2 matrix calculated.
