Basic Graph Functions

scatter plot

cars <- cars
str(cars)
head(cars)

在这里插入图片描述

cars <- cars
str(cars)
head(cars)
plot(cars$dist~cars$speed, # y~x
     pch=19,#Set the plotting symbol to filled dots
     col='lightblue',#Set the color of plotting symbol to red
     main="Relationship between car distance & speed", # Plot aTitle
     xlab="Speed (miles per hour)", #X axis title
     ylab="Distance travelled (miles)", #Y axis title
     xlim=c(0,30), #Set x axis limits from 0 to 30
     ylim=c(0,140), #Set y axis limits from 0 to 140
     xaxs="i", #Set x axis style as internal
     yaxs="i", #Set y axis style as internal
     )

在这里插入图片描述

line graphs

plot(cars$dist~cars$speed,
type="l", #Specify type of plot as l for line
col='blue',
main="Relationship between car distance & speed",
xlab="Speed miles per hour",
ylab="Distance travelled (miles)")
