Dataset Help

On this Picostat.com statistics page, you will find information about the Riders data set which pertains to Volume of Users of a Massachusetts Rail Trail. The Riders data set is found in the mosaicData R package. You can load the Riders data set in R by issuing the following command at the console data("Riders"). This will load the data into a variable called Riders. If R says the Riders data set is not found, you can try installing the package by issuing this command install.packages("mosaicData") 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 Riders R data set. The size of this file is about 5,095 bytes.

Documentation

Volume of Users of a Massachusetts Rail Trail

Description

The Pioneer Valley Planning Commission (PVPC) collected data north of Chestnut Street in Florence, MA for ninety days from April 5, 2005 to November 15, 2005. Data collectors set up a laser sensor, with breaks in the laser beam recording when a rail-trail user passed the data collection station.

Usage

data(Riders)

Format

A data frame with 90 observations on the following 12 variables.

date

date of data collection (POSIXct)

day

a factor with levels Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday.

highT

high temperature for the day (in degrees Fahrenheit)

lowT

low temperature for the day (in degrees Fahrenheit)

hi

shorter name for highT

lo

shorter name for lowT

precip

inches of precipitation

clouds

measure of cloud cover (in oktas)

riders

estimated number of trail crossings that day (number of breaks recorded)

ct

shorter name for riders

weekday

type of day: a factor with levels N (weekend or holiday) Y (non-holiday weekday)

wday

shorter name for weekday

Details

There is a potential for error when two users trigger the infrared beam at exactly the same time since the counter would only logs one of the crossings. The collectors left the motion detector out during the winter, but because the counter drops data when the temperature falls below 14 degrees Fahrenheit, there are no data for the coldest winter months.
