On this Picostat.com statistics page, you will find information about the Minard.cities data set which pertains to Data from Minard's famous graphic map of Napoleon's march on Moscow. The Minard.cities data set is found in the HistData R package. Try to load the Minard.cities data set in R by issuing the following command at the console data("Minard.cities"). This may load the data into a variable called Minard.cities. If R says the Minard.cities data set is not found, you can try installing the package by issuing this command install.packages("HistData") and then attempt to reload the data with library("HistData") followed by data("Minard.cities"). 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 Minard.cities 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 Minard.cities R data set. The size of this file is about 417 bytes.
Data from Minard's famous graphic map of Napoleon's march on Moscow
Charles Joseph Minard's graphic depiction of the fate of Napoleon's Grand
Army in the Russian campaign of 1815 has been called the "greatest statistical graphic
ever drawn" (Tufte, 1983). Friendly (2002) describes some background
for this graphic, and presented it as Minard's Chalenge: to reproduce it using
modern statistical or graphic software, in a way that showed the elegance of
some computer language to both describe and produce this graphic.
Minard.troops: A data frame with 51 observations on the following 5 variables giving the number
of surviving troops.
Number of surviving troops, a numeric vector
a factor with levels
a numeric vector
Minard.cities: A data frame with 20 observations on the following 3 variables giving the locations of
various places along the path of Napoleon's army.
City name: a factor with levels
Minard.temp: A data frame with 9 observations on the following 4 variables, giving the temperature
at various places along the march of retreat from Moscow.
Number of days on the retreat march
a factor with levels
Minard.temp should be made a real date in 1815.
