R Dataset / Package boot / gravity
On this Picostat.com statistics page, you will find information about the gravity data set which pertains to Acceleration Due to Gravity. The gravity data set is found in the boot R package. Try to load the gravity data set in R by issuing the following command at the console data("gravity"). This may load the data into a variable called gravity. If R says the gravity data set is not found, you can try installing the package by issuing this command install.packages("boot") and then attempt to reload the data with library("boot") followed by data("gravity"). 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 gravity 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 gravity R data set. The size of this file is about 585 bytes.
Acceleration Due to Gravity
Between May 1934 and July 1935, the National Bureau of Standards in Washington D.C. conducted a series of experiments to estimate the acceleration due to gravity, g, at Washington. Each experiment produced a number of replicate estimates of g using the same methodology. Although the basic method remained the same for all experiments, that of the reversible pendulum, there were changes in configuration.
