function.
is.genind
tests if an object is a valid genind object.

genind(tab,pop=NULL,prevcall=NULL, ploidy=2) as.genind(tab,pop=NULL,prevcall=NULL, ploidy=2) is.genind(x)
tab |
a individuals x alleles matrix of genotypes coded as allelic frequencies, i.e. like in a genind object |
pop |
a factor giving the population of each genotype in 'x' |
prevcall |
call of an object |
ploidy |
an integer indicating the degree of ploidy of the genotypes. Beware: 2 is not an integer, but as.integer(2) is. |
x |
an object |
