The BEAGLE program generates, for each SNP and each subject,
posterior probabilities for the three genotypes. This function reads
such data as a
SnpMatrix object, storing the posterior
probabilities to as much accuracy allowed by a one-byte coding
The input file name. This file my be gzipped.
The row names (sample identifiers) for the matrix
The number of SNPs to be read in. This corresponds with the number of lines in the input file. If not supplied, the function does a preliminary pass to determine the number of lines
In later versions of BEAGLE, row names are listed on a header line.
However, if the
rownames argument is supplied, this will
take precedence over the header line. If there is no header
line and no row names are supplied, names
are generated as
No provision is made for data for the X chromosome. Such data must be
first read as a
SnpMatrix and subsequently coerced to an
