Examples

# read in expected value data from Gary White
data("NSpeciesOcc")
# process data and specify number of species=5 in the mixtures argument
dp=process.data(NSpeciesOcc,model="NSpeciesOcc",mixtures=5)
# make design data and fit model used to generate the data
ddl=make.design.data(dp)
# The following has been commented out because it would not work on CRAN Linux version
# Remove comment to run
#model=mark(dp,ddl,model.parameters=list(f=list(formula=~-1+mixture,link="sin"),
#p=list(formula=~1,link="sin")),delete=TRUE)
