This function superposes two graphics and extends the graphical constraints of a first graphic to a second one.

`g1` |
an object of class |

`g2` |
an object of class |

`e1` |
an object of class |

`e2` |
an object of class |

`which` |
if |

`plot` |
a logical indicating if the graphics is displayed |

The created `ADEgS`

object is a layout of two graphical objects.
Each of the two objects superposed still have its graphical parameters in the created layout.
However, the `ADEgS`

displayed favour the graphical parameters of the object below :
displayed limits, grid, legend and axes are those of `g1`

(respectively `e1`

) and `g2`

(respectively `e2`

) has transparent background and labels' boxes.

The `superpose`

method is defined for:

`signature(g1 = "ADEgS", g2 = "ADEg", which = "numeric", plot = "logical")`

`signature(g1 = "ADEgS", g2 = "ADEg", which = "numeric", plot = "ANY")`

`signature(g1 = "ADEgS", g2 = "ADEg", which = "missing", plot = "ANY")`

: If`which`

is`missing`

, the last`ADEg`

of`g1@ADEglist`

is used as the base of superposition. In that case,`which = length(g1)`

`signature(g1 = "ADEgORtrellis", g2 = "ADEgORtrellis", which = "ANY", plot = "ANY")`

: If`g1`

is an`ADEg`

object, no`which`

is needed.`signature(g1 = "ADEgS", g2 = "ADEgS", which = "missing", plot = "ANY")`

The `+`

method is defined for:

`signature(e1 = "ADEg", e2 = "ADEg")`

: superpose e2 on e1`signature(e1 = "ADEg", e2 = "ADEgS")`

: superpose e2 to e1`signature(e1 = "ADEgS", e2 = "ADEg")`

: calls the`+`

method with signature`(e1 = "ADEg", e2 = "ADEgS")`

.

An object of class `"ADEgS"`

.
