Read in network model data files that are in the SCOR format (REFERENCE).
Usage
read.scor(file,from.file=TRUE,warn = FALSE)
Arguments
file
File path or plain text.
from.file
States whether the file argument input should be treated as a file path (TRUE)
or plain text (FALSE).
warn
Turn on (TRUE) or off (FALSE) warnings.
Value
Returns the network model in one of several formats. The default
format is a network object used by the statnet package
(type="network"). Three other options are the network environ analysis
format (type="nea") as defined by (Fath and Borrett 2006), a list
format (type="list") and an edge list (type="edge.list").
Details
The SCOR file must be formatted properly. In particular, the number of
nodes on the second line must have the first three characters
dedicated to the total number of nodes and the next three characters
should contain the number of living nodes. That is, the second line of
the file should be formatted as 'xxxyyy' where x and y are the
characters for the total number of nodes and the number of living
nodes, respectively. Thus, if the total number of nodes is 10 and the
number of living nodes is 1, then the second line should read, " 10
1."
