st: news modules on SSC

[Jean-Benoit Hardouin <jean-benoit.hardouin@orscentre.org>]

Thanks to Kit Baum two new modules are available on SSC :
      - -biplotvlab- is an improvement of the Ken Higbee's code  
presented yesterday on the Statalist to draw a biplot graph with  the 
label of the variables. The improvements concern a gap between  the text 
and the ends of the arrows, and the possibility to give  characteristics 
to the texts (color, size...). The labels of the  variables are 
displayed and, if one or several variables have not a  label, the name 
of these variables are displayed. For example this  module is a nice way 
to produce biplots with temporary variables.
     - -genscore- is a small module to easily create a new  variable 
containing the score computed as the sum or the mean of  several 
variables. It is possible to define a given modality as a  missing 
value. I think that this module could be improved by  integrating it in 
-egen- (for the next version of this module ?)
