R Dataset / Package DAAG / hotspots

On this R-data statistics page, you will find information about the hotspots data set which pertains to Hawaian island chain hotspot Potassium-Argon ages. The hotspots data set is found in the DAAG R package. You can load the hotspots data set in R by issuing the following command at the console data("hotspots"). This will load the data into a variable called hotspots. If R says the hotspots 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 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 hotspots R data set. The size of this file is about 1,285 bytes.

Hawaian island chain hotspot Potassium-Argon ages

Description

K-Ar Ages (millions of years) and distances (km) from Kilauea along the trend of the chain of Hawaian volcanic islands and other seamounts that are believed to have been created by a moving "hot spot". The age of Kilauea is given as 0-0.4 Ma.

Usage

data(hotspots)

Format

A data frame with 36 observations on the following 6 variables.

ID: Volcano identifier
name: Name
distance: Distance in kilometers
age: K-Ar age in millions of years
error: Standard error of estimate?
source: Data source; see information on web site below.

Details

For details of the way that errors werre calculated, refer to the original papers. See also the comments under hotspots2006. In general, errors do not account for geological uncertainty.
