How To Make Scatterplot

My Statistic teacher asked me to make Scatterplot using R.

For this statistic class, we are asked to work with R, not Excel. So I have to download the software in my computer. 

You can download the free software here https://cran.r-project.org/bin/windows/base/ 

Scatterplot using R

data1=read.csv("beer.csv")

attach(data1)

plot(PercentAlcohol,Carbohydrates)

To make the Regression Line

data1=read.csv("beer.csv")

attach(data1)

plot(PercentAlcohol,Carbohydrates, main= "Scatterplot of Carbohydrates Versus Percent Alcohol")

x= PercentAlcohol

z= Calories

y= Carbohydrates

r=cor (Carbohydrates, PercentAlcohol)

sc= sd ( Carbohydrates)

sp= sd ( PercentAlcohol)

b1= r* (sc/sp)

b0= mean(y)-b1*mean(x)

abline(b0,b1,col=2)

See the differences of these two scatterplots
