No, but (1) pathDiagram() (the name of the function in the current version
of the sem package) produces an editable text file, from which you could
remove the arrows that you don't want to see; and (2) you could modify
pathDiagram() -- the code for the function is, after all, available to you
-- so that it does what you want.
I hope this helps,
