R: Creates object of class angledist
angledistR Documentation

Creates object of class angledist


Creates a leaf angle distribution object. Other functions in the LeafAngle package use this type of object quite conveniently. Nearly all distributions summarized in Wang et al. (2007) are implemented.


angledist(distribution, distpars = NA)



One of the distributions. Currently included are 'ellipsoid', 'rotatedell', 'twoparbeta', 'spherical', 'planophile', 'extremophile', 'erectophile', 'uniform', and 'plagiophile'.


A vector of parameters for the distribution. See Details.


Only three of the distributions take a parameter, these are 'ellipsoid' and 'rotatedell', and 'twoparbeta'. For the first two, the parameter X needs to be provided, for the 'twoparbeta' the parameters alphamean and tvar (see Wang et al. 2007).


An object of class AngleDist. Simply a list of components, in this useage only two are set: distribution and distpars. Other components are set when fitting a distribution to data, see fitdistribution.
