3D-Data Plotting In R

Assignment 1: Create 3 vectors, x, y, z and choose any random values for them, ensuring they are of equal length,T<- cbind(x,y,z) and Create 3 dimensional plot of the same

Solution:

plot3d(m)

plot3d(T,col=rainbow(1000),type='s')

Assignment no 2: Create 2 random variables and create 3 plots: 

 X-Y ,X-Y|Z (introducing a variable z and cbind it to x and y with 5 diff categories) 

> x<-rnorm(1500,100,10)

> y<-rnorm(1500,85,5)

> z1<-sample(letters,5)

> z2<-sample(z1,1500,replace=TRUE)

> z<-as.factor(z2)

> t<-cbind(x,y,z)

 qplot(x,y)

qplot(x,z)

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

qplot(x,y,colour=z)

qplot(log(x),log(y),colour=z)
