LeafAngle (version 1.2-1)

ftheta: Density and cumulative probability functions for leaf angle distributions

Description

ftheta is the density function, Ftheta gives the cumulative probability of a leaf angle, given some distrbution. Useful in plotting curves, otherwise not typically needed by user (see fitdistribution instead.

Usage

fthetacum(angles, degrees = TRUE, ...) fthetaf(angle,angledistobj=NULL,degrees=FALSE,distribution,distpars=NA) ftheta(distpars=NA,...)

Arguments

angles
Vector of leaf angles (0-90 degrees)
angle
Leaf angle (degrees)
degrees
Logical.
angledistobj
Object of class 'angledist'.
distribution
Name of distribution.
distpars
Parameters.
...
None.

Value

A vector of densities or probabilities.
