simulate.transectHolder function

Function to simulate a modelled seed rain from a transectHolder

This function simulates a two-dimensional seed rain according to the model stored in a transectHolder object. The angle of the seed location from the parent plant is uniformly distributed on [0, 2 pi).

## S3 method for class transectHolder 
## S3 method for class 'transectHolder'
simulate(object, nsim=1, seed=NULL, ...)

Arguments

• object: the transectHolder object for simulation
• nsim: the number of seeds to simulate.
• seed: if not NULL, set the seed to this value before simulation.
• ...: additional optional arguments (ignored here).

Returns

A dataframe with n rows with the following components: - distances: seed distances to parent plant

• angles: seed angles to parent plant, in radians

• x: x-location of seed

• y: y-location of seed

                        seed.counts = c(4, 3, 2, 0))
transect.2 <- trapTransect(distances = 1:3,
                        seed.counts = c(3, 2, 1))
transect.3 <- trapTransect(distances=(1:5)/2,
                        seed.counts = c(3, 4, 2, 3, 1))
