plot3dPdf {longitudinalData}

~ 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

## S4 method for signature 'LongData3d,missing'
plot3dPdf(x,y,varY=1,varZ=2)
## S4 method for signature '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.

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 software asymptote to convert '.asy' to '.pre'. This is done by the command asy -inlineimage -tex pdflatex scene.asy (not in R, in a console).

4. The previous step did produce a file scene+0.prc that can be include in a LaTeX file. makeLatexFile create a LaTeX file that is directly compilable (using pdfLatex). It produce a pdf file that contain the 3D object.

Value

A Triangle object.

Examples

  ### Move to tempdir
  wd <- getwd()
  setwd(tempdir()); getwd()
  
  ### Generating the data
  data(artificialJointLongData)
  myLd <- longData3d(artificialJointLongData,timeInData=list(var1=2:12,var2=13:23))
  part <- partition(rep(1:3,each=50))
  plotTrajMeans3d(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
  
  ### Go back to current dir
  setwd(wd)
