To open R with the dataset preloaded, right-click here and choose "Save Target As" to download the file to your computer. Then find the downloaded file and double-click it to open it in R.
The data have been loaded into the data frame h
. Enter the command h
to see the data. There are three variables in h
: gender
, height
, and weight
.
The variables are identified as follows:
gender
: 0 = male, 1 = female.
height
: in inches.
weight
: in pounds.
First we will create a scatterplot to examine how weight is related to height, ignoring gender.
To do that in R, copy the following command to R:
plot(h$height,h$weight)
Again, a good graphic should have labels so lets add x and y-axis labels:
plot(h$height,h$weight, xlab="Height (inches)", ylab="Weight (lbs)")
