grid |
The |
x |
Array of X-coordinates of the grid |
y |
Array of Y-coordinates of the grid |
z |
Matrix containing the variable to be represented in isolines |
pos.x |
Index of the field used for abcissae |
pos.y |
Index of the field for the ordinate |
zlim |
The bounds for the 'image' representation |
col |
Color of the symbol foreground for the samples whose target variable lies within the bounds. In the case of a grid, color scale used to represent the grid. |
boundmin |
Minimum value to be represented |
boundmax |
Maximum value to be represented |
extend.colors |
When TRUE and if zlim has been defined, the pixels below zlim[1] (resp. above zlim[2]) are represented with the first (resp. last) color of the colors scale. |
pos.legend |
