Use this script:
# load the iris datasetdata <- read.csv("http://archive.ics.uci.edu/ml/machine-learning-databases/iris/iris.data")#Let us also clean up the data so as to be more readablecolnames(data) <- c("sepal_length", "sepal_width", "petal_length", "petal_width", "species")pairs(data)
This produces this graphic:

The pairs graphic shows petal width and petal length as related (fairly good straight lines of the plot points), and little relationship between sepal length and sepal width.
