Introduction
--------------------------------------------------------------------------------
R uses 2 graphics libs trellis and graphics that use 2 différent parameters structures.
Part of those structures may be redefined in file ~/.datamind/config_plot.R which is source
before each plot.
Graphics and lattice may be redefined using the classical par() and 
trellis.par.get()/trellis.par.set() functions.


--------------------------------------------------------------------------------
Examples:
--------------------------------------------------------------------------------

## Coppy the folowing in ~/.datamind/config_plot.R -----------
# Symbol: darkblue filled bullet pch=16
plot_symb=trellis.par.get("superpose.symbol")
plot_symb$col="darkblue"
plot_symb$pch=16
trellis.par.set("plot.symbol", plot_symb)

# If several symbol are ploted
# then lattice function use superpose.symbol instead of plot.symbol
sup_symb=trellis.par.get("superpose.symbol")
sup_symb$col[1]="darkblue"
sup_symb$col[2]="red"
sup_symb$pch=c(16,16,16,16,16,16,16)
trellis.par.set("superpose.symbol", sup_symb)

## --------
# Line: darkblue
plot_line=trellis.par.get("plot.line")
plot_line$col="darkblue"
trellis.par.set("plot.line", plot_line)

# if several symbol are ploted
# then lattice function use superpose.line instead of plot.line
sup_line=trellis.par.get("superpose.line")
sup_line$col[1]="darkblue"
sup_line$col[2]="red"
trellis.par.set("superpose.line", sup_line)
