draw.gradient {RGeostats} | R Documentation |
Internal function for representing the gradient components
draw.gradient(x, y, elev, gx, gy, grad.size = 1., flag.normal=TRUE, flag.grad.pt=TRUE, ...)
x |
Array giving the coordinates of the samples along X |
y |
Array giving the coordinates of the samples along Y |
elev |
Array giving the values of the samples (only used for RGL representation) |
gx |
Array giving the gradient components of the samples along X |
gy |
Array giving the gradient components of the samples along Y |
grad.size |
Scale factor to convert a gradient unit into a field unit. |
flag.normal |
When TRUE, the normal is represented. When FALSE, the tangent is represented |
flag.grad.pt |
When TRUE, the location of the information is represented. |
... |
When all dimensions of the gradient are zero, the sample is represented using the characteristics provided by the user, but with a pattern representation fixed to pch=10.
