x |
Array giving the coordinates of the samples along X |
y |
Array giving the coordinates of the samples along Y |
z |
Array giving the target variable |
elev |
Array giving the values of the samples (only used for RGL representation) |
zmin |
Minimum acceptable value for the target variable. |
zmax |
Maximum acceptable value for the target variable. |
include.bounds |
When TRUE, the limiting bounds are included |
inches |
Reference size for proportional representation. The sizes of the symbols vary from inches*0.1 to inches*1. |
fg.low |
Color of the symbol foreground for samples whose target variable is smaller than zmin |
bg.low |
Color of the symbol background for samples whose target variable is smaller than zmin |
pch.low |
Symbol type for representing for samples whose target variable is smaller than zmin |
cex.low |
Symbol size for representing for samples whose target variable is smaller than zmin. If the size if set to zero, these samples are not plotted. |
fg.up |
Color of the symbol foreground for samples whose target variable is larger than zmax |
bg.up |
Color of the symbol background for samples whose target variable is larger than zmax |
pch.up |
Symbol type for representing samples whose target variable is larger than zmax |
cex.up |
Symbol size for representing samples whose target variable is larger than zmax. If the size if set to zero, these samples are not plotted. |
col |
Color of the symbol foreground for the samples whose target variable lies within the bounds. If not provided as a constant value, the color assigned to each sample is interpolated. |
bg |
Color of the symbol background for the samples whose target variable lies within the bounds. If not provided as a constant value, the colors assigned to each sample is interpolated. |
pch |
Symbol type for representing samples whose target variable lies between the bounds |
cex0 |
Smallest symbol size used for representing samples whose target variable belongs to the interval [zmin,zmax]. |
cex1 |
Largest symbol size used for representing samples whose target variable belongs to the interval [zmin,zmax]. |
flag.abs |
When TRUE, the absolute value of the target variable is considered |
pos.legend |
Position of the optional legend. See |

When representing symbols for variable lying within [zmin,zmax], the symbol size is calculated by the following formula: cex0 + (cex1 - cex0) * (z - zmin) / (zmax - zmin)
