Arguments
dim
Dimensions to be used for biplot (default is c(1,2)).
map.dim
Third dimension used to map aesthetic attributes (depth)
(default is 3).
e.label.cex
Size of the element labels. Two values can be entered that will
represents the lower and upper size of a range of cex the values of map.dim
are mapped onto. The default is c(.4, .8). If only one cex value
is supplied (e.g. .7) no mapping occurs and all element labels
will have the same size irrespective of their value on the map.dim
dimension.
c.label.cex
Size of the construct labels. Two values can be entered that will
represents the lower and upper size of a range of cex the values of map.dim
are mapped onto. The default is c(.4, .8). If only one cex value
is supplied (e.g. .7) no mapping occurs and all construct labels
will have the same size irrespective of their value on the map.dim
dimension.
e.label.col
Color(s) of the element labels. Two values can be entered that will
create a color ramp. The values of map.dim are mapped onto the ramp.
The default is c("white", "black"). If only one color color value
is supplied (e.g. "black") no mapping occurs and all element labels
will have the same color irrespective of their value on the map.dim
dimension.
c.label.col
Color(s) of the construct labels. Two values can be entered that will
create a color ramp. The values of map.dim are mapped onto the ramp.
The default is c("white", "black"). If only one color color value
is supplied (e.g. "black") no mapping occurs and all construct labels
will have the same color irrespective of their value on the map.dim
dimension.
e.point.cex
Size of the element symbols. Two values can be entered that will
represents the lower and upper size of a range of cex the values of map.dim
are mapped onto. The default is c(.4, .8). If only one cex value
is supplied (e.g. .7) no mapping occurs and all elements
will have the same size irrespective of their value on the map.dim
dimension.
c.point.cex
Size of the construct symbols. Two values can be entered that will
represents the lower and upper size of a range of cex the values of map.dim
are mapped onto. The default is c(.4, .8). If only one cex value
is supplied (e.g. .7) no mapping occurs and all elements
will have the same size irrespective of their value on the map.dim
dimension.
e.point.col
Color(s) of the element symbols. Two values can be entered that will
create a color ramp. The values of map.dim are mapped onto the ramp.
The default is c("white", "black"). If only one color color value
is supplied (e.g. "black") no mapping occurs and all elements
will have the same color irrespective of their value on the map.dim
dimension.
c.point.col
Color(s) of the construct symbols. Two values can be entered that will
create a color ramp. The values of map.dim are mapped onto the ramp.
The default is c("white", "darkred"). If only one color color value
is supplied (e.g. "black") no mapping occurs and all elements
will have the same color irrespective of their value on the map.dim
dimension.
e.color.map
Value range to determine what range of the color ramp defined in
e.color will be used for mapping the colors.
Default is c(.4, ,1). Usually not important for the user.
c.color.map
Value range to determine what range of the color ramp defined in
c.color will be used for mapping. Default is c(.4, ,1).
Usually not important for the user.
unity
Scale elements and constructs coordinates to unit scale in 2D (maximum of 1)
so they are printed more neatly (default TRUE).
unity3d
Scale elements and constructs coordinates to unit scale in 3D (maximum of 1)
so they are printed more neatly (default TRUE).
scale.e
Scaling factor for element vectors. Will cause element points to move a bit more
to the center. This argument is for visual appeal only.
devangle
The deviation angle from the x-y plane in degrees. These can only be calculated
if a third dimension map.dim is specified. Only the constructs
vectors that do not depart
more than the specified degrees from the shown x-y plane will be printed.
This facilitates the visual interpretation, as only vectors represented in
the current plane are shown. Set the value to 91 (default)
to show all vectors.
