In tilltnet/egonetR: Import and analyse ego-centric network data

Ego-centererd network data includes three kinds of data:

1. Ego data
2. Alteri data
3. Edge data

The inforamtion on the egos is usually stored in a dataframe.

Alteri data can be stored in a single dataframe with the alteri as the rows (long-format), the data might be split up into seperate files for each ego/ network or it might be in the same dataset as the egos data, with the alteri information in colums or as variables (wide-format.)

Finally the edges can be stored as edgelists (in one or in seperate files), as matrices or in colums of a dataframe (wide-format).

egonetR helps with the importing of all these formats into R, by providing seperate functions that are dedicated to handle each kind of format. In addition there are three funtcions that let you import all of the data in one line of code:

Single Command Import

egonetR supports importing three different data formats with a single command. These are:

• One-File: All the data is stored in one file; egos as rows; alteri and edge data in the wide-format.

• Two-Files: Ego data and edges (wide-format) are stored in one file and the alteri (long-format) in another.

• Folders: Egos in one file; folders of files per ego for alteri and edges.

Formats that can be imported using Single Command Import

One- & Two-File(s) Format

In order to import data stored in the One- or Two-File(s) format you need to load the datasets intro R first. If your data is stored as .csv-Files, use the read.csv() or read.csv2() command.

One-File:

setwd(system.file("extdata", package = "egonetR"))

egos_one <- read.csv2("one_file_8.csv")

Two-Files:

setwd(system.file("extdata", package = "egonetR"))

egos_two <- read.csv2("two_files_8_egos.csv")

alteri_two <- read.csv2("alteri_8.csv")

read.egonet.one.file(egos, netsize,  netID = "netID", attr.start.col, attr.end.col, dy.max.alteri, dy.first.var)

read.egonet.two.files(egos, long, netsize = NULL,  netID = "netID", alterID = NULL, dy.max.alteri, dy.first.var)

read.egonet.folders(egos, alter.folder, edge.folder, netID = "netID")
