Generic function for calculating individual-level diversity.
inddiv(data, qs)# S4 method for powermean
inddiv(data, qs)
# S4 method for relativeentropy
inddiv(data, qs)
# S4 method for metacommunity
inddiv(data, qs)
matrix
of mode numeric
; containing diversity
components
vector
of mode numeric
containing q values
inddiv()
returns a standard output of class rdiv
data
may be input as three different classes:
power_mean
: calculates raw and normalised subcommunity alpha, rho
or gamma diversity by taking the powermean of diversity components
relativeentropy
: calculates raw or normalised subcommunity beta
diversity by taking the relative entropy of diversity components
metacommunity
: calculates all subcommunity measures of diversity

subdiv
for subcommunity-level diversity and
metadiv
for metacommunity-level diversity.
# NOT RUN {
# Define metacommunity
pop <- cbind.data.frame(A = c(1,1), B = c(2,0), C = c(3,1))
row.names(pop) <- paste0("sp", 1:2)
pop <- pop/sum(pop)
meta <- metacommunity(pop)
# Calculate subcommunity gamma diversity (takes the power mean)
g <- raw_gamma(meta)
inddiv(g, 0:2)
# Calculate subcommunity beta diversity (takes the relative entropy)
b <- raw_beta(meta)
inddiv(b, 0:2)
# Calculate all measures of individual diversity
inddiv(meta, 0:2)
