adegpar can be used to set or query graphical parameters used in ADEg object display.
It is inspired by the par function of graphics package.
adegpar(...)Several parameters are used to create complete plot and accessible through adegpar.
p1d:parameters for one-dimension graphic, object of class inherited from "ADEg.S1" or "ADEg.C1"
horizontal: a logical indicating if the plot is horizontal
reverse: a logical indicating if the bottom of the plot is at the bottom (for horizontal as TRUE)
or at the left of the device (for horizontal as FALSE). If FALSE, the graphical display bottom is at the top
(for horizontal as TRUE) or at the right of the device (for horizontal as FALSE).

be drawn. Legend can be provided by the key argument or
is automatically generated for *.class and *.value
functions
drawColorKey: a logical indicating if the color
legend should be drawn (only for *.image functions)
size: size of the legend
plines:lines' drawing parameters
col: lines color
lty: lines type
lwd: lines width
pnb:drawing parameters for neighbourhood graph

pch: node's symbol type
cex: node's symbol size
col: node's symbol color
alpha: a value between 0 and 1 controlling node's symbol transparency
porigin:drawing parameters for origin's lines. See panel.lines for more information
draw: a logical indicating if vertical and horizontal lines are drawn to indicate origin
include: a logical indicating if origin is included in the drawing limits
origin: a two-length vector indicating origin coordinates
alpha: a value between 0 and 1 controlling origin's lines transparency
col: color of origin's lines
lty: origin's line type
lwd: origin's line width
ppalette:a function taking one integer in argument indicating the number of expecting colors (for example using colorRampPalette)
quanti: adegpar()$ppalette$quanti(n) returns n colors shaded grey to white
quali: adegpar()$ppalette$quali(n, name) returns n differentiated colors. name argument is passed to the brewer.pal function
of the RColorBrewer package and must be Accent, Dark2, Paired, Pastel1, Pastel2, Set1 (the default value), Set2 or Set3.
When n is equal to 2, values for 'white' and 'black' colors are returned and can be not quite visible on the display.
ppoints:points' drawing paameters
alpha: a value between 0 and 1 controlling points transparency
cex: points size
col: points color

psub:subtitle's drawing parameters
cex: text size of subtitle
col: text color of subtitle
position: a character string (topright, topleft, bottomleft, bottomright) or a vector of length 2
indicating text position of subtitle. If it is a vector, the default unit is npc (normalized parent coordinates).
text: the character string to display
ptable:for table graphic, object of class inherited from ADEg.T
x: x-axis parameters
srt: text rotation
pos: position of the axis. It can be top or bottom. Otherwise axis and labels' axis are not drawn
tck: ticks size
adj: justification of labels
y: same as x list, but for y-axis
str, tck, adj
pos: position of the axis. It can be left or right. Otherwise axis and labels' axis are not drawn
margin: margin surrounding the drawing panel. The numbers indicate the bottom, left, top and right margins.
Results are obtained passing margin to padding argument in lattice. Please see
layout.heights and layout.widths parameters in lattice package for more information
If it is empty, the return value is a named list containing all the current settings.
If it is a string of characters, the corresponding sub-list of parameters is return as information.
If it is a list containing keys and values, the corresponding changes in current settings are made.

The graphical parameters control apparency of the graphic.
Calls can be made using either a list of list (e.g. plabels = list(col = "red")) or a list grouping both keys with "." (e.g. plabels.col = "red").
Parameters are re-used if needed in all ADEg object.
If set globally, meaning using adegpar, all created objects afterwards will be affected.
