I am trying to write a script to run occupancy analysis for very large
sets of data for multiple species. I have in the past used PRESENCE but
would like to use R. I am having trouble getting the ObsCov into the
data frame. I get the following error message:




Error in validObject(.Object) : 

invalid class "unmarkedFrame" object: obsCovData does not have M*obsNum


Lastly, I have multiple species in each data set (some as many as 128).
Can i put all species in one unmarkedFrameOccu then call out a species
as I need it or do i need a separate unmarkedFrameOccu for each species?
