# s1d.gauss: 1-D plot of a numeric score by Gaussian curves In adegraphics: An S4 Lattice-Based Package for the Representation of Multivariate Data

## Description

This function represents a score with a Gauss curve for each level of a factor.

## Usage

 ```1 2 3 4``` ```s1d.gauss(score, fac = gl(1, NROW(score)), wt = rep(1, NROW(score)), steps = 200, col = NULL, fill = TRUE, facets = NULL, plot = TRUE, storeData = TRUE, add = FALSE, pos = -1, ...) ```

## Arguments

 `score` a numeric vector (or a data frame) used to produce the plot `fac` a factor (or a matrix of factors) to split `score` `wt` a vector of weights for `score` `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 `score` so that subsets of the data are represented on different sub-graphics `plot` a logical indicating if the graphics is displayed `storeData` a logical indicating if the data are stored in the returned object. If `FALSE`, only the names of the data arguments are stored `add` a logical. If `TRUE`, the graphic is superposed to the graphics already plotted in the current device `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 `storeData` is `FALSE` `...` additional graphical parameters (see `adegpar` and `trellis.par.get`)

## Details

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.

## Value

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`.
