[R-pkgs] version 3.0-0 of the sem now on CRAN

[John Fox]

Dear R users,

Version 3.0-0 of the sem package is now on CRAN. From the package NEWS file:

	o Compiled code for optimization.
	
	o Added multi-group models.
	
	o Modification indices for equality-constrained parameters.
	
	o weights argument added to tsls().
	
	o raw argument added to cfa().

Of these changes, the first two are the most significant, and the first --
the use of compiled code to improve performance substantially -- was
implemented by Zhengua Nie, who has joined me and Jarrett Byrnes as a
co-developer of the package.

Best,
 John
