This convenience function converts multi-year data in long format to unmarkedMultFrame Object. See Details for more information.
formatMult(df.in)unmarkedMultFrame object
a data.frame appropriately formatted (see Details).
df.in is a data frame with columns formatted as follows:
Column 1 = year number
Column 2 = site name or number
Column 3 = julian date or chronological sample number during year
Column 4 = observations (y)
Column 5 -- Final Column = covariates
Note that if the data is already in wide format, it may be easier to create an unmarkedMultFrame object
directly with a call to unmarkedMultFrame.
