Analysis scripts and data for "The dynamics of cooperation and social status in a small-scale society"

Requirements:

Instructions:

In R, set the working directory to that containing this readme file. On Mac, for example, you could say

setwd('~/Desktop/dynamics_cooperation_status_analysis')

Check to see if you're in the right place by typing dir() and see whether this readme file is present.

The longitudinal analysis uses six data files as input:

'village1_cooperation_t1.csv' - The cooperation network at time point 1 \
'village1_cooperation_t2.csv' - The cooperation network at time point 2 \
'village1_cooperation_t3.csv' - The cooperation network at time point 3 \
'village1_kinship_t1.csv' - The kinship network at time point 1 \
'village1_kinship_t2.csv' - The kinship network at time point 2 \
'village1_attributes.csv' - Includes status, physical strength and size, income and log age \

Please note that only data from the first two time points are used for varying covariates, and dyadic varying covariates (kinship), in the analysis. Another important note is that the rows and columns in the cooperation and kinship matrices represent the individuals nominating. At each time point rows do not change and represent the same individuals as the rows in the attributes files.

When the project folder is the working directory, the longitudinal analysis may run itself (assuming that you have installed all of the dependencies) by calling

source('./village1_SAOM.R')

However, I would advise to run the analysis script in blocks.

The cross-sectional analysis uses six data files as input:

'village2_cooperation.csv' - The cooperation network \
'village2_kinship.csv' - The kinship network \
'village2_attributes.csv' - The attributes of actors (i.e. status, strength and size, income, log age)

There are three data files that only include participants with full data:

'village2_cooperation_deleted.csv' - The cooperation network \
'village2_kinship_deleted.csv' - The kinship network \
'village2_attributes_deleted.csv' - The attributes of actors (i.e. status, strength and size, income, log age)

When the project folder is the working directory, the cross-sectional analysis may run itself (assuming that you have installed all of the dependencies) by calling

source('village2_ERGM.R')

However, I would advise to run the analysis script in blocks.

The anaylses may take some time. The total time until completion may vary by machine.

The project is maintained by Daniel Redhead (daniel_redhead@eva.mpg.de) and is hosted at https://github.com/danielRedhead
