read.egonet.two.files: Import ego-centric network data from two file format
In tilltnet/egonetR: Import and analyse ego-centric network data

Description Usage Arguments Value

This function imports ego-centric network data, stored in two files, where one file contains the ego attributes and the edge information and the other file contains the alteri data. This form of data storage for ego-centered network data is proposed by Muller, Wellman and Marin (1999).

read.egonet.two.files(egos, alteri, netsize = NULL, egoID = "egoID",
  alterID = NULL, e.max.alteri, e.first.var, ego.vars = NULL,
  selection = NULL)

`egos`	`Data frame` containg ego data (egos as cases)
`alteri`	`Data frame` containing alteri data (alteri as cases), alteri are separated by a variable containg an egoID.
`netsize`	`Vector` containing values of network size per ego.
`egoID`	`Character`. Name of the variable identifying egos (default: "egoID").
`alterID`	`Character`. Name of the variable identifying alteri (default: "alterID").
`e.max.alteri`	Maximum number of alteri that are included in edge data.
`e.first.var`	Index of first column in `egos` containing edge data.
`ego.vars`	`Character vector` naming variables in the egos data, in order to copy them in to the long alteri `dataframe`.
`selection`	`Character` naming `numeric` variable indicating alteri selection with zeros and ones.

A list of six objects - the **egoR** object: (1) egos.df: dataframe of all egos and their attributes; (2) alteri.df: dataframe of all alteri; (3) alteri.list: list of dataframes of all alteri per ego; (4) edges: list of dataframes with edge lists per network; (5) graphs: list of igraph objects; (6) results: a result dataframe, pre-populated with the network size of each network
