R Dataset / Package MASS / Sitka
On this Picostat.com statistics page, you will find information about the Sitka data set which pertains to Growth Curves for Sitka Spruce Trees in 1988. The Sitka data set is found in the MASS R package. Try to load the Sitka data set in R by issuing the following command at the console data("Sitka"). This may load the data into a variable called Sitka. If R says the Sitka data set is not found, you can try installing the package by issuing this command install.packages("MASS") and then attempt to reload the data with library("MASS") followed by data("Sitka"). Perhaps strangley, if R gives you no output after entering a command, it means the command succeeded. If it succeeded you can see the data by typing Sitka at the command-line which should display the entire dataset.
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 Sitka R data set. The size of this file is about 8,084 bytes.
