Plot3()
displays three-dimensional data in two dimensions, reflecting the
third dimension with point scaling, overlap and fogging.
Points with a lower z
value are smaller than, fainter than, and overlapped
by points with a higher value.
Coordinates of points to plot.
Parameters passed to
plot.default()
.
Colour with which to fill plot area, used as fog colour.
Numeric from zero (no fading) to one (furthest points are invisible) specifying amount to fade distant points.
Numeric specifying degree to which size of plotted point
should reflect z
position. 0
denotes no scaling; if 1
, furthest
point will have zero size.
Plot3(1:10, 1:10, 1:10, cex = 7, pch = 16, axes = FALSE, asp = 1)
# Extreme values of fog and shrink will cause smallest z values to
# become invisible.
