**Introduction:**

The main
objective of this study is to learn to plot the cumulative distribution
function, quantiles and probability mass function using simple R commands.

R Commands:

·
seq
– is used to generate a sequence of values.

·
pnorm
– is used to calculate the cumulative distribution function.

·
dnorm
– is used to calculate the probability mass function

·
qnorm-
is used to generate quantiles or inverse of the normal distribution.

R commands
and images:

**Using Pnorm:**

·
x<-
seq(-5,5, length = 250)

·
plot(x,pnorm(x),
type ="l", lwd = 2, col ="blue", xlab =" x
values", ylab = "CDF")

**Using dnorm:**

·
x<-
seq(-5,5, length = 250)

·
plot(x,dnorm(x),
type ="l", lwd = 2, col ="blue", xlab =" x
values", ylab = "PDF")

The primary goal is to understand the commands in R that help in creating basic statistical images. Readers can use Wikipedia in order to learn more about normal distribution and its usefulness in statistics and economics.
