Description Usage Format Author(s) See Also Examples

A vector of integers which assigns each variable (genotype marker) to a particular group. The clustering was performed via the R package BALD. This package uses linkage disequilibrium as a measure of proximity. In total, 98 groups are available. Group sizes vary from 1 to 23. The median of group sizes is equal to 3. For more details about the distribution of group sizes, please check out the example below.

groups

## Create a vector with group sizes:
sizes <- rep(as.integer(NA), max(groups))
for (i in 1:98) {
  sizes[i] = max(which(groups==i)) - min(which(groups==i)) + 1
}

## Plot the sorted group sizes:
plot(x = seq(1, max(groups), 1), y = sort(sizes))
