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:
data1=unmarkedFrameOccu(y=y,siteCovs=siC,obsCov=suC) Error in validObject(.Object) : invalid class "unmarkedFrame" object: obsCovData does not have M*obsNum rows 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?
