Description Usage Arguments Details Value Author(s) Examples

The inbreedR working format is an i * l genotype matrix, whereby each individual is a row and each column is a locus. Heterozygosity at a given locus should be coded as 1, homozygosity as 0 and missing values should be coded as NA.

1	check_data(genotypes, num_ind = NULL, num_loci = NULL)

`genotypes`	`data.frame` (or `matrix`) with individuals in rows and loci in columns, containing genotypes coded as `0` (homozygote), `1` (heterozygote) and `NA` (missing)
`num_ind`	Number of individuals
`num_loci`	Number of loci / markers

Checks that (1) the genotype data just contains 3 elements, which is 0 for homozygote, 1 for heterozygote and NA for missing data, (2) the number of individuals corresponds to the number of rows and the number of loci corresponds to the number of columns, (3) the data type is numeric. .

TRUE if the data format is correct, error message if any test failed
