On this Picostat.com statistics page, you will find information about the iris data set which pertains to Edgar Anderson's Iris Data. The iris data set is found in the datasets R package. You can load the iris data set in R by issuing the following command at the console data("iris"). This will load the data into a variable called iris. If R says the iris data set is not found, you can try installing the package by issuing this command install.packages("datasets") and then attempt to reload the data. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the iris R data set. The size of this file is about 4,026 bytes. |

Edgar Anderson's Iris DataDescriptionThis famous (Fisher's or Anderson's) iris data set gives the measurements in centimeters of the variables sepal length and width and petal length and width, respectively, for 50 flowers from each of 3 species of iris. The species are Iris setosa, versicolor, and virginica. Usageiris iris3 Format
