Possible control
arguments are:
Computation of Cell Mapping:
gcm.approach
: Which approach should be used when
computing the representatives of a cell. The default is "min"
,
i.e. the observation with the best (minimum) value within per cell.
gcm.cf_power
: Theoretically, we need to compute the
canonical form to the power of infinity. However, we use this value
as approximation of infinity. The default is 256
.
Plot Control:
bt.cm_surface
: Should the underlying surface be based
on a cell mapping plot (default is TRUE
)? Alternatively, the
cells would be coloured in shades of grey - according to their
objective values.
bt.margin
: Margins of the plot as used by
par("mar")
. The default is c(5, 5, 4, 4)
.
bt.color_surface
: Color of the surface of the
perspective plot. The default is "lightgrey"
.
bt.color_branches
: Color used for the branches of the
barrier tree. Per default there will be one color per level.
bt.pch_root
: Symbol used for plotting the root.
The default is 17
(filled triangle).
bt.pch_breakpoint
: Symbol used for plotting a
breakpoint. The default is 5
(non-filled diamond).
bt.pch_basin
: Symbol used for plotting the leaf (i.e. a
basin) of the barrier tree. The default is 19
(filled circle).
bt.col_root
: Color of the root symbol. The default is
"red"
.
bt.lwd
: Width of the lines used for plotting the
branches of a barrier tree. The default is 2
.
bt.label.{x, y}_coord
: Label of the x-/y-coordinate
(below / left side of the plot).
bt.label.{x, y}_id
: Label of the x-/y-cell ID (above /
right side of the plot).
