perspectev.calc {perspectev}

Calculate upper and lower level trait values and survivorship

Description

Calculates upper and lower level trait values and survivorship given a data set and trait functions

Usage

perspectev.calc(data,traitfun,vlist=list(),na.rm=FALSE)

Arguments

data

Dataframe in perspectev format (see below).

traitfun

Function for calculating trait value at each level.

vlist

Optional variable list for trait function.

na.rm

Remove NA values from trait functions? Shouldn't need to be used if trim=TRUE from perspectev.read.

Value

upper

Table of survivorship and trait value at upper level (scaled to mean 0 and variance 1)

lower

Table of survivorship and trait value at lower level (scaled to mean 0 and variance 1)

stats

[1]: correlation between upper level trait and survivorship, [2-4]: quantiles of upper level trait values (unscaled)
