This function represents a score with a Gauss curve for each level of a factor.
1 2 3 4 
score 
a numeric vector (or a data frame) used to produce the plot 
fac 
a factor (or a matrix of factors) to split 
wt 
a vector of weights for 
steps 
a value for the number of segments used to draw the Gauss curves 
col 
a logical, a color or a colors vector for labels, rugs, lines and polygons according to their factor level. Colors are recycled whether there are not one color by factor level. 
fill 
a logical to yield the polygons Gauss curves filled 
facets 
a factor splitting 
plot 
a logical indicating if the graphics is displayed 
storeData 
a logical indicating if the data are stored in
the returned object. If 
add 
a logical. If 
pos 
an integer indicating the position of the
environment where the data are stored, relative to the environment
where the function is called. Useful only if 
... 
additional graphical parameters (see

Graphical parameters for rugs are available in plines
of adegpar
and the ones for Gauss curves filled in ppolygons
.
Some appropriated graphical parameters in p1d
are also available.
An object of class ADEg
(subclass C1.gauss
) or ADEgS
(if add
is TRUE
and/or
if facets or data frame for score
or data frame for fac
are used).
The result is displayed if plot
is TRUE
.
