R Dataset / Package Stat2Data / Pines
On this R-data statistics page, you will find information about the Pines data set which pertains to Pines. The Pines data set is found in the Stat2Data R package. You can load the Pines data set in R by issuing the following command at the console data("Pines"). This will load the data into a variable called Pines. If R says the Pines data set is not found, you can try installing the package by issuing this command install.packages("Stat2Data") and then attempt to reload the data with the library() command. 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 Pines R data set. The size of this file is about 45,329 bytes.

Details
This dataset contains information data from an experiment conducted by the Department of Biology at Kenyon College at a site near the campus in Gambier, Ohio. In April 1990, student and faculty volunteers planted 1000 white pine (Pinus strobes) seedlings at the Brown Family Environmental Center. These seedlings were planted in two grids, distinguished by 10- and 15-foot spacings between the seedlings. Several variables were measured and recorded for each seedling over time (in 1990, 1996, and 1997).
