Clusters SNPs hierachically.
The SNP data matrix of size
The agglomeration method to be used. This should be

The SNPs are clustered using
which performs a hierarchical cluster analysis using a set of dissimilarities
nvar objects being clustered. There are 3 possible scenarios.
d = NULL,
x is used to compute the dissimilarity matrix.
The dissimilarity measure between two SNPs is
1 - LD (Linkage
LD is defined as the square of the Pearson
correlation coefficient. If
SNP_index = NULL, all
nvar SNPs will
be clustered; otherwise only the SNPs with indices specified by
will be considered.
If the user wishes to use a different dissimilarity measure,
to be provided.
d must be either a square matrix of size
nvar x nvar, or an object of class
SNP_index will be ignored.
