output.file

name of the file on which the matrix must be written.

digits

number of digits to be used to save scores of m (def. digits=3). The extension of the file can be plain (".txt") or compressed (".gz").

Value

A tupla score matrix stored in output.file.

Details

Only the non-zero interactions are kept, while the zero interactions are discarded.

Examples

# NOT RUN {
data(wadj);
file <- tempfile();
tupla.matrix(W, output.file=file, digits=3);
# }
