These files are for a graphics competition to be held in January 2006. See THIS LINK for details.
The basic idea is to summarize the data graphically in the "best" way possible. It might be a fun thing to try your hand at.
Documentation for the data is found at THIS LINK.
The file read.files.R contains some R code to read these data sets into R. To use these functions, download them into R with this command:
source("http://wiener.math.csi.cuny.edu/verzani/classes/MTH410/GraphicsCompetition/read.files.R")
Then to grab the second temperature file, you can do
x = read.files(name="temperature",number=2)
A contour plot shows some information:
contour(x)
To grab all the temperature data, you can do:
x = readAsZOOObject(name="temperature")(You need the zoo package installed here)
A plot of the first 10 time series can be had with
plot(x[,1:10])
For those who prefer Fahrenheit over Kelvin, we have
KtoF = function(x) 9/5*(x-273)+32 plot(KtoF(x[,1:10]))
The zoo object makes plots easy. An array is a bit more convenient for storing the data.
a = zooObjectToArray(x) contour(as.numeric(dimnames(a)[[1]]),27:50, a[,1,])
