### Simple models without stratification
### Import and filter data
data(alcidae)
alcids <- mcds.filter(alcidae, transect.id = "WatchID", distance.field = "Distance", distance.labels = c("A", "B", "C", "D"), 
                         distance.midpoints = c(25, 75, 150, 250), effort.field = "WatchLenKm", lat.field = "LatStart", 
                         long.field = "LongStart", sp.field = "Alpha", date.field = "Date") 

### Run analysis with the MCDS engine. Here, the WatchID is used as the sample.
dist.out1 <- mcds.wrap(alcids, SMP_EFFORT="WatchLenKm",DISTANCE="Distance",SIZE="Count",Type="Line",
                         units=list(Distance="Perp",Length_units="Kilometers",
                                    Distance_units="Meters",Area_units="Square kilometers"),
                         breaks=c(0,50,100,200,300), estimator=list(c("HN","CO")),
