dat.nakagawa2007: Assessing the Function of House Sparrows' Bib Size Using a Flexible Meta-Analysis Method

Description

A meta-analysis on the association between the size of a male's bib and their social status in house sparrows (Passer domesticus).

Usage

dat.nakagawa2007

Format

The data frame contains the following columns:

StudyID	character	identity of primary study
Place	character	location of study population
Correlation	numeric	correlation coefficient
SampleSize	integer	sample size of population

Author

Daniel Noble,

Concepts

ecology, correlation coefficients

Details

Each study measures the association between a sparrows bib size and its social status. Effects are quantified as correlation coefficients.

Examples

### copy data into 'dat' and examine data
dat <- dat.nakagawa2007
dat

if (FALSE) {
### load metafor package
library(metafor)

### calculate Zr
dat <- escalc(measure="ZCOR", ri=Correlation, ni=SampleSize, data=dat)

### fit meta-analytic model
res <- rma.mv(yi, vi, random = ~ 1 | StudyID, data=dat)
res
}
