Examples

require(vegsoup)

data(barmstein)
x <- barmstein

abundant(x) # with default values
abundant(x, treshold = 50) # treshold set to 50% constancy
abundant(x, treshold = 75, layers = TRUE) # include layers

x <- VegsoupPartition(barmstein, k = 2)
abundant(x) # threshold applied over all partitions
abundant(partition(x, 1)) # for a selected partition
abundant(partition(x, 2), layers = TRUE) # for a selected partition with layers
