R Dataset / Package datasets / volcano
On this Picostat.com statistics page, you will find information about the volcano data set which pertains to Topographic Information on Auckland's Maunga Whau Volcano. The volcano data set is found in the datasets R package. Try to load the volcano data set in R by issuing the following command at the console data("volcano"). This may load the data into a variable called volcano. If R says the volcano 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 with library("datasets") followed by data("volcano"). 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 volcano 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 volcano R data set. The size of this file is about 21,167 bytes.
Topographic Information on Auckland's Maunga Whau Volcano
Maunga Whau (Mt Eden) is one of about 50 volcanos in the Auckland volcanic field. This data set gives topographic information for Maunga Whau on a 10m by 10m grid.
A matrix with 87 rows and 61 columns, rows corresponding to grid lines running east to west and columns to grid lines running south to north.
Digitized from a topographic map by Ross Ihaka. These data should not be regarded as accurate.
