Description Usage Arguments Details Value Author(s) See Also Examples

create.dataset creates a data set with a given percentage of masked data from the original data set. It is used to calculate the cross.entropy criterion.

1	create.dataset (input.file, output.file, seed = -1, percentage = 0.05)

`input.file`	A character string containing a path to the input file, a genotypic matrix in the `geno` format.
`output.file`	A character string containing a path to the output file, a genotypic matrix in the `geno` format. The output file is the input file with masked genotypes. By default, the name of the output file is the same name as the input file with a _I.geno extension.
`seed`	A seed to initialize the random number generator. By default, the seed is randomly chosen.
`percentage`	A numeric value between 0 and 1 containing the percentage of masked genotypes.

This is an internal function, automatically called by snmf with the entropy option.

output.file

A character string containing a path to the output file, a genotypic matrix in the geno format.
