Description Usage Arguments Value Author(s) See Also Examples

Function for easily read genomic data in vcf-Format to a list, which contains the map information and the marker information.

1	read.vcf2list(file, FORMAT = "GT", coding = c("allele", "ref"), IDinRow = TRUE, cores=1)

`file`	`character`. The name of the file which the data are to be read from.
`FORMAT`	`character`. The default is `"GT"`. If there are more formats in your vcf-file you can decide which one you like to have in your output matrix.
`coding`	This option has only an effect with `FORMAT="GT"`. `allele` gives you back the alles as defined as REF and ALT in your vcf-file. `ref` gives you back `"0"` for the reference allele and `"1"` for the alternative allele.
`IDinRow`	`logical`. Default is `TRUE`, this means the genotypes are in the rows and the markers in the column. For `FALSE` it is the other way round.
`cores`	`numeric`. Specifies the number of cores for parallel computing.

A list with a matrix (matrix) containing a representation of the genotypic data in the file and a map of classes GenMap and data.frame.
