Probability Distribution and Cumulative Density Functions

R has four built-in functions to generate normal distributions

-qnorm()

-rnorm()

-pnorm()

• dnorm()

x=seq(1,10,by=0.1)

y=rnorm(x,1,2)

plot(x,y,col=rainbow(100))

Cumulative distribution function

x=seq(1,10,by=0.1)

y=pnorm(x,5,1)

plot(x,y, col=rainbow(100))

Probability distribution function

x=seq(1,10,by=0.1)

y=dnorm(x,5,1)

plot(x,y,col=rainbow(100))
