	* R/pcalg.R (randomDAG): Bug fix (Empty graph could not be
	transformed into adj matrix with as(G,"matrix"). Although it worked
	with wgtMatrix, it was still worth fixing.

	* R/pcalg.R (idaFast): Included rownames indicating the element of
	y.pos.set, to which the line corresponds

	* man/skeleton.Rd (fixedEdges): removed x11() and added split window

	* man/pc.Rd (fixedEdges): removed x11() and added split window

	* R/pcalg.R (ida): No change in functionality; changed
	implementation of argument y.notparent so that it is easier to
	understand. Checked that old and new version give identical results
	on 100 random graphs.

	* DESCRIPTION (Version): 1.0-1

	* R/pcalg.R (plot-methods, plotSG): need Rgraphviz::plot() now that Rgraphviz is
	not imported *before* method definition.

	* R/AllClasses.R: move class definitions here (at least).

	* pcalg.R (plotSG): add 'main' argument; do *return* the subgraph,
	clean up code.
	* man/plotSG.Rd: document 'main', use markup (\code{..}) properly.

2010-03-22  Markus Kalisch  <kalisch@stat.math.ethz.ch>

	* NAMESPACE: no longer import (from) Rgraphviz
	* DESCRIPTION: ditto
