A number of standard distributions to fit to (plant) leaf angle distributions: a special kind of distribution where 0 <= angle <= 90 (degrees). Based on the list of distributions summarized by Wang et al. (2007). Uses maximum-likelihood to find parameters, determines best fitting distributions, and includes some simple plotting methods.

loglikfit
(Package: LeafAngle) :
Two methods for fitting a leaf angle distribution
Two functions that report the chi-squared statistic, or the log-likelihood of a particular distribution, given a sample of leaf angles. No need to be called by the user. Simply use fitdistribution, which finds the parameters of the distribution by minimizing either chi-squared or log-likelihood.

Fits all distributions, returns an object of a special class. Prints nicely to show the statistic of the fit, and which one is the 'best fit'.

Fits one of nine leaf angle distributions to data, using either log-likelihood (the preferred method), or a method based on minimizing the chi-squared statistic. This latter method is included to be consistent with Wang et al. (2007), as well as others.

angledist
(Package: LeafAngle) :
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.
