R Dataset / Package DAAG / hotspots2006


On this Picostat.com statistics page, you will find information about the hotspots2006 data set which pertains to Hawaian island chain hotspot Argon-Argon ages. The hotspots2006 data set is found in the DAAG R package. You can load the hotspots2006 data set in R by issuing the following command at the console data("hotspots2006"). This will load the data into a variable called hotspots2006. If R says the hotspots2006 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. 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 hotspots2006 R data set. The size of this file is about 378 bytes.

Hawaian island chain hotspot Argon-Argon ages


Ar-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".




A data frame with 10 observations on the following 6 variables.


Ar-Ar age


Measurement error; 95% CI


Geological Uncertainty


Total uncertainty (+)


Total uncertainty (-)


Distance in kilometers


Note that measurement error is small relative to geological uncertainty. Geological uncertainty arises because lavas are likely to have erupted, over a period of up to 2 million years, somewhat after passage over the hot spot's centre. Dredging or drilling will in general have accessed larvas from the younger half of this interval. Hence the asymmetry in the geological uncertainty.
