longitudinalData (version 2.0)

plot3dPdf: ~ Function: plot3dPdf for LongData ~

Description

Given a LongData and a Partition, this function create 'Triangle objects' representing the 3D plot the clusters centers. Triangle object can latter be used to include dynamic rotating graph in a pdf file.

Usage

## S3 method for class 'LongData3d,missing':
plot3dPdf(x,y,varY=1,varZ=2)
## S3 method for class 'LongData3d,numeric':
plot3dPdf(x,y,varY=1,varZ=2)

Arguments

x

[LongData]: Object containing the trajectories to plot.

y

[numeric]: Partition that will be use to plot the object.

varY

[numeric] or [character]: either the number or the name of the first variable to display. 1 by default.

varZ

[numeric] or [character]: either the number or the name of the second variable to display. 2 by default.

Value

• A Triangle object.

Details

Create Triangle objects representing the 3D plot of the main trajectories of a LongData. The three functions plot3dPdf, saveTrianglesAsASY and makeLatexFile are design to export a 3D graph to a Pdf file. The process is the following:

1. plot3dPdf: Create a scene, that is a collection of Triangle object that represent a 3D images.
2. saveTrianglesAsASY: Export the scene in an '.asy' file.
3. '.asy' can not be include in LaTeX file. LaTeX can read only '.pre' file. So the next step is to use the softwareasymptoteto convert '.asy' to '.pre'. This is done by the commandasy -inlineimage -tex pdflatex scene.asy(not in R, in a console).
4. The previous step did produce a filescene+0.prcthat can be include in a LaTeX file.makeLatexFilecreate a LaTeX file that is directly compilable (usingpdfLatex). It produce a pdf file that contain the 3D object.

Examples

### Generating the data
  myLd <- gald3d()
  part <- partition(rep(1:3,each=50))
  plot3d(myLd,part)

  ### Creation of the scene
  scene <- plot3dPdf(myLd,part)
  drawScene.rgl(scene)

  ### Export in '.asy' file
  saveTrianglesAsASY(scene)

  ### Creation of a '.prc' file
  # Open a console, then run:
  # 'asy -inlineimage -tex pdflatex scene.asy'

  ### Creation of the LaTeX main document
  makeLatexFile()

  ### Creation of the '.pdf'
  # Open a console window, then run
  # pdfLatex main.tex
