filledcylinder

adds a colored and rotated cylinder to a plot


Description

adds a rotated and colored cylinder to a plot; color can be a palette

Usage

filledcylinder(rx = 1, ry = rx, len = 1, col = femmecol(100), 
              lcol = NA, lwd = 2, lcolint = NULL, ltyint = 1, 
              lwdint = lwd, mid = c(0,0), angle = 0, delt = 1,
              dr = 0.01, topcol = NULL, botcol = NULL, ...)

Arguments

rx

horizontal radius.

ry

vertical radius.

len

length.

col

color palette to be used; also allowed are two extremes or one value.

lcol

line color on external surface.

lwd

only if lcol!=NA, width of external line.

lcolint

only if lcol!=NA, line color on internal (hidden) surface.

ltyint

only if lcol!=NA, line type on internal (hidden) surface.

lwdint

only if dlcol!=NA, line width on internal (hidden) surface.

mid

midpoint of cylinder.

angle

rotation angle, degrees.

delt

increase factor, from left to right.

dr

size of segments, in radians, to draw top/bottom ellipse (decrease for smoother).

topcol

color (palette) of top (right) surface.

botcol

color (palette) of bottom (left) surface.

...

arguments passed to function filledellipse.

Details

When angle = 0 (the default), the cylinder is parallel to the x-axis

rx and ry are the horizontal and vertical radiusses of the bordering ellipses. Here "horizontal" and "vertical" denote the position BEFORE rotation

if delt > 1, the width of the cylinder will increase from left to right.
