unmarkedPowerList: Summarize a series of unmarked power analyses

In rbchan/unmarked: Models for Data from Unmarked Animals

Summarize a series of unmarked power analyses

Description

A list of power analyses created with powerAnalysis can be combined using unmarkedPowerList, allowing comparison e.g. between different study designs/sample sizes. A series of methods for unmarkedPowerList objects are available including a plot method.

Usage

## S4 method for signature 'unmarkedPower'
unmarkedPowerList(object, ...)
## S4 method for signature 'unmarkedPowerList'
show(object)
## S4 method for signature 'unmarkedPowerList'
summary(object, showIntercepts = FALSE, ...)
## S4 method for signature 'unmarkedPowerList,ANY'
plot(x, power=NULL, param=NULL, ...)

Arguments

object, x	For unmarkedPowerList, an unmarkedPower object. For show, summary, plot, an unmarkedPowerList object.
showIntercepts	Show intercepts output? This is rarely useful.
power	If specified, adds a dotted line to the plot at this target power value.
param	When plotting, the model parameter to plot power vs. sample size for. By default this is the first parameter.
...	For unmarkedPowerList, other unmarkedPower objects to combine into the list.

Value

A unmarkedPowerList object, a summary of the object in the console, or a summary plot, depending on the method

Examples

## Not run: 

# Build unmarkedFrame
umf <- unmarkedFrameOccu(y = matrix(NA, 300, 8),
                         siteCovs = data.frame(elev=rnorm(300)))

# Run power analyses
cf <- list(state = c(0, -0.4), det = 0)
pa1 <- powerAnalysis(umf, model=occu, formula=~1~elev, effects=cf)
pa2 <- powerAnalysis(umf[1:100,], model=occu, formula=~1~elev, effects=cf)

# Combine them into a list
(pl <- unmarkedPowerList(pa1, pa2))

# Look at summary plot for elev effect
plot(pl, power=0.8, param='elev')
