Plotting in R

Session 10, March 26th, 2013

Assignment 1: 

Create 3 vectors x,y,z and choose any random values for them.

T<-cbind(x,y,z)

Create 3-dimentional plot of the same

plot3d(T)

 plot3d(T,col=rainbow(1000))

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

Assignment 2 : 

Create 2 random variables x,y & create a few plots showing

• X-Y
• X-Y|Z ( Introduce a variable z and cbind it to z and y with 5 different categories ... Hint : ?factor)
• Color code and draw the graph
• Smooth and fit line for the curve

qplot(x,y)

qplot(x,z)

 qplot(x,z,alpha=I(1/10))

qplot(x,z,alpha = I(1/30))

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

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

qplot(x,y,colour=z)

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