ScrData: Spatial capture-recapture data class
In r-glennie/openpopscr: Open Population Spatial Capture-Recapture

Encapsulates data from spatial capture-recapture survey into a single object. Object can be created using $new with arguments:

capthist: capture history object from secr package with trap information included
mesh: mask object from secr package
time: optional vector of numeric time each occasion took place at (used for irregularly spaced occasions). Default is vector of ones.
cov: a list of covariate (for detector and occasion)
cov_type: type of covariate (j = detector cov, k = occasion cov, jk = detector+occasion,)

Methods include:

capthist(): return capture history object
traps(): return traps object
mesh(): return mesh object
time(): return time vector
covs(j, k): return covariate values at detector j on occasion k
n(): return number of individuals seen over the entire survey
n_occasions(): return number of capture occasions in the survey
n_traps(): return number of traps used at some time in the survey
n_meshpts(): return number of mesh points
area(): return total area of the mesh
add_covariate(covariate_name, covariate_dataframe, covariate_type): add covariate to object
distance(): return matrix with (i,j)th entry the distance from trap i to mesh point j
