This function computes the population parameter THETA using the expected number of alleles.
a vector or a factor.
a numeric giving the sample size.
a numeric giving the number of alleles.
This function can be used in two ways: either with a vector giving the
individual genotypes from which the sample size and number of alleles
are derived (e.g.,
theta.k(x)), or giving directly these two
theta.k(n = 50, k = 5)).
x can be either a factor or a vector. If it is a
factor, then it is taken to give the individual alleles in the
population. If it is a numeric vector, then its values are taken to be
the numbers of each allele in the population. If it is a non-numeric
vector, it is a coerced as a factor.
k must be single numeric values.
A numeric vector of length one with the estimated theta.
For the moment, no standard-error or confidence interval is computed.
