Calculates `banking' slope
banking(dx, dy)
dx, dy |
vector of consecutive x, y differences. |
banking is a crude banking function used when aspect="xy" in
high level Trellis functions. Its usually not very menaingful except
for xyplot. It just orders the absolute slopes and returns a value
which when adjusted by the panel scale limits will make the median of
the above absolute slopes a 45 degree line.
