On this Picostat.com statistics page, you will find information about the traffic1 data set which pertains to traffic1. The traffic1 data set is found in the wooldridge R package. Try to load the traffic1 data set in R by issuing the following command at the console data("traffic1"). This may load the data into a variable called traffic1. If R says the traffic1 data set is not found, you can try installing the package by issuing this command install.packages("wooldridge") and then attempt to reload the data with library("wooldridge") followed by data("traffic1"). 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 traffic1 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 traffic1 R data set. The size of this file is about 3,516 bytes.
Data loads lazily. Type data(traffic1) into the console.
