How to implement Scatter3D using plot3D package in R?


To implement the Scatter3D using plot3D package in R programming.

   R Package : plot3D

   R Function : scatter3D()

   R Function : text3D()

   R Function : points3D()

   R Function : text2D()

   R Function : scatter2D()

x, y, z -- vectors of point coordinates

colvar -- a variable used for coloring

col -- color palette used for coloringthe colvar variable

labels --the text to be written

add -- logical. If TRUE, then the points will be added to the current plot.If FALSE a new plot is started

pch -- changes point shapes

cex -- changes the size of points

Type of Box:

f -- full box

b -- default value. Only theU backpanels are visible

b2 -- back panels and grid lines arevisible

g -- grey background with white gridlines

bl -- black background

bl2 -- black background withgrey lines

u -means that the user willspecify the arguments col.axis,col.panel, lwd.panel, col.grid,lwd.grid manually

n -- no box will be drawn.This is the same as setting box = FALSE

Color Palette

col(n, alpha): generates thematlab-type colors.

This isthe default color palette usedin plot3D

col(n, alpha): similar to jet.col()but lacks the deep blue colors col(n, alpha)and gg2.col(n, alpha)generates gg-plot-like colors

col(col = c(grey, black), n,alpha): creates color schemes by

interpolation col(col = grey, alpha): creates transparent colors

Tick Marks

simple draws just an arrow parallelto the axis to indicate directionof increase

detailed draws normal ticks and labels

nticks: the number of tick marksto draw on the axes. It has no effectif ticktype =simple.
