dyncohort: Interactive graphs of dynamic cohorts.

Description

dyncohort produces interactive graphs representing dynamic cohorts. Two periods or lifes belongs to the same cohort if there are a difference of years in their start less or equal to a given number. In case of people's life, 15 or 25 are appropiate quantities to set. If year is equal to 0, a cohort is defined a those periods or lifes that begin at the same year.

Usage

dyncohort(periods, name="name", start="start", fields=names(periods), 
          years=0, igraph=FALSE, ...)

Value

This function creates a timeCoin object (or igraph) and, if plotted, a folder in the computer with an HTML document named index.html which contains the produced graph. This file can be directly opened with your browser and sent to a web server to work properly.

A netCoin object has three elements:

nodes: A data frame with the periods.
links: A data frame with the events.
options: A list of options for the interactive graph.

Arguments

periods: a data frame with at least two vectors with name and start of the periods or lives.
name: name of the vector with names in the data frame.
start: name of the vector with starts in the data frame.
fields: vector of the names of the periods data frame to be taken into account.
years: number of years to be considered as length of the cohort.
igraph: produces an igraph object instead of a netCoin class.
...: Any netCoin argument.

Run this code

# With sociologists data.
data(sociologists)
dyncohort(sociologists, start="birth")
# Condider 15 year dynamic cohort:
sociologists$picture <- system.file("extdata", sociologists$picture,
        package="netCoin") # copy path to the picture field
dyncohort(sociologists, start="birth", year=15, image="picture", imageName="name")
