On this Picostat.com statistics page, you will find information about the leafshape data set which pertains to Full Leaf Shape Data Set. The leafshape data set is found in the DAAG R package. You can load the leafshape data set in R by issuing the following command at the console data("leafshape"). This will load the data into a variable called leafshape. If R says the leafshape 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.
