3D PLOTTING


Assignment 1: 

Create 3 vectors, x, y, z and choose any random values for them, ensuring they are of equal length, bind them together.Create 3 dimensional plots of the same.

Data Set Creation Commands and DataSet :


Plotting 3D plot:

Normal Plot:   plot3d(T[, 1:3])


Colour Plot: plot3d(T[, 1:3], col = rainbow(1000))


Color Plot of spheres:  plot3d(T[, 1:3], col = rainbow(1000), type = 's')




Assignment 2:

Choose 2 random variables 
Create 3 plots: 
1. X-Y 
2. X-Y|Z (introducing a variable z and cbind it to z and y with 5 diff categories)
3. Color code and draw the graph 
4. Smooth and best fit line for the curve


Data set creation for two random variables and then introducing third variable z



Plots:

>qplot(x,y)


>qplot(x,z)


Semi-transparent plot

> qplot(x,z, alpha=I(2/10))


Colour plot

> qplot(x,y, color=z)

Logarithmic colour plot

> qplot(log(x),log(y), color=z)




Best Fit and Smooth curve using "geom"

> qplot(x,y,geom=c("path","smooth"))




> qplot(x,y,geom=c("point","smooth"))




> qplot(x,y,geom=c("boxplot","jitter"))
