R Dataset / Package DAAG / cuckoos


On this R-data statistics page, you will find information about the cuckoos data set which pertains to Cuckoo Eggs Data. The cuckoos data set is found in the DAAG R package. You can load the cuckoos data set in R by issuing the following command at the console data("cuckoos"). This will load the data into a variable called cuckoos. If R says the cuckoos data set is not found, you can try installing the package by issuing this command install.packages("DAAG") 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 cuckoos R data set. The size of this file is about 3,062 bytes.

Cuckoo Eggs Data

This data frame contains the following columns:


the egg lengths in millimeters


the egg breadths in millimeters


a factor with levels hedge.sparrow, meadow.pipit, pied.wagtail, robin, tree.pipit, wren


a numeric vector
