L1cent(), L1centNB(), L1centLOC() now support (strongly connected) directed graphs. Use the new parameter mode to measures the prominence of each vertex in terms of making a choice (mode = "centrality") or receiving a choice (mode = "prestige"). If the graph is undirected, mode does not affect the outcome.Minor typo fix in the document.
\() changed to function() for compatibility (L1centNB.matrix()).
Fixed error in the L1centLOC() function.
Added package overview table to the L1centrality-package document.
arXiv URL added to the package description and function documents.
Minor typo fix in the document.
L1centLOC() and L1centEDGE() made more efficient.
\() changed to function() for compatibility (L1centMDS.matrix()).
The vertex multiplicity parameter eta generalized to nonnegative values (L1cent(), L1centEDGE(), L1centLOC(), L1centNB()). It previously accepted only positive values.
L1centMDS(), setting verbose=FALSE suppresses all the console messages. In the previous version, the final message was printed even when verbose=FALSE.
