mia: Multiple imputation analysis for hap

Description

This command reads outputs from hap session that uses multiple imputations, i.e. -mi# option. To simplify matters it assumes -ss option is specified together with -mi option there.

Usage

mia(
  hapfile = "hap.out",
  assfile = "assign.out",
  miafile = "mia.out",
  so = 0,
  ns = 0,
  mi = 0,
  allsnps = 0,
  sas = 0
)

Value

The returned value is a list.

Arguments

hapfile

hap haplotype output file name.

assfile

hap assignment output file name.

miafile

mia output file name.

so

to generate results according to subject order.

ns

do not sort in subject order.

mi

number of multiple imputations used in hap.

allsnps

all loci are SNPs.

sas

produce SAS data step program.

Details

This is a very naive version of MIANALYZE, but can produce results for PROC MIANALYZE of SAS.

It simply extracts outputs from hap.

Examples

if (FALSE) {
# 4 SNP example, to generate hap.out and assign.out alone
data(fsnps)
hap(id=fsnps[,1],data=fsnps[,3:10],nloci=4)

# to generate results of imputations
control <- hap.control(ss=1,mi=5)
hap(id=fsnps[,1],data=fsnps[,3:10],nloci=4,control=control)

# to extract information from the second run above
mia(so=1,ns=1,mi=5)
file.show("mia.out")
