pillar3D function

Create a 3D pillar chart to display (x, y, z) data coordinate surface.

Given data on (x, y, z) coordinate values of a 3D surface, one can directly plot a 3D plot with pins of the height z. By contrast, this function fattens each pin by creating pillars near each z value by adding and subtracting small amounts of dz. By eliminating the pins of the height z, this depicts pillars that better resemble a surface. It uses the wireframe() function of the `lattice' package to do the plotting.

pillar3D(
  z = c(657, 936, 1111, 1201),
  x = c(280, 542, 722, 1168),
  y = c(162, 214, 186, 246),
  drape = TRUE,
  xlab = "y",
  ylab = "x",
  zlab = "z",
  mymain = "Pillar Chart"
)

Arguments

• z: z-coordinate values
• x: x-coordinate values
• y: y-coordinate values
• drape: logical value, default drape=TRUE to give color to heights
• xlab: default "x" label on the x axis
• ylab: default "y" label on the y axis
• zlab: default "z" label on the z axis
• mymain: default "Pillar Chart" main label on the plot

Returns

A 3D plot

Details

For additional plotting features the user should type `pillar3D()' on the R console to get my code and adjust my wireframe() function defaults.
