Standard Deck of Cards

Description

A character vector with two or three character representations of each card in a standard 52-card deck.

Usage

Cards

Details

The 2 of clubs is represented as "2C", while the 10 of diamonds is "10D".

Examples

if (require(mosaic)) {
  deal(Cards, 13)        # bridge hand
  deal(Cards, 5)         # poker hand
  shuffle(Cards)         # shuffled deck

CoolingWater

Description

Temperature of a mug of water as it cools

Usage

data(CoolingWater)

Format

A data frame with 222 observations of the following variables.

time: time in minutes
temp: temperature in Celsius

Details

The water was poured into a mug and a temperature probe inserted into the water with a few seconds of the pour.

Source

These data were collected Stan Wagon to help his mathematical modeling students explore Newton's Law of Cooling and the ways that the law is really only an approximation. More about Stan: http://stanwagon.com.

Examples

data(CoolingWater)
if (require(ggformula)) {
  gf_point(temp ~ time, data = CoolingWater, alpha = 0.5)
}

Countries

Description

A data frame containing country names as used by Gapminder and the maps package to facilitate conversation between the two.

Usage

data(Countries)

Format

A data frame with 258 observations on the following variables.

maptools: region name http://mappinghacks.com/ data sets
gapminder: country name in Gapminder data sets
maps: region name in maps data sets

Details

The "countries" in the maps data include several other geographic regions (bodies of water, islands belonging to other countries, Hawaii, etc.) that are not countries. Furthermore, the maps countries do not include many of the countries that have been created since ca. 2000. The mapping is therefore many-to-many, and also includes some NAs when there is no appropriate mapping. Bodies of water in the maps data, for example, are not assigned a country in the Gapminder.

Examples

data(Countries)
subset(Countries, maps=="Yugoslavia")  # Where has Yugoslavia gone?
subset(Countries, is.na(gapminder))    # Things from maps with no Gapminder equivalent
subset(Countries, is.na(maps))         # Things from Gapminder with no maps equivalent

Weight of dimes

Description

Weights of a sample of dimes.

Usage

data(Dimes)

Format

A data frame with 30 observations on the following 2 variables.

mass: mass of dime in grams
year: year the dime was minted

Details

These data were collected on a sample taken from a large sack of dimes for the purpose of estimating the total number of dimes in the sack based on the weights of the individual dimes.

Source

Data were collected by Michael Stob.

Galton's dataset of parent and child heights

Description

In the 1880's, Francis Galton was developing ways to quantify the heritability of traits. As part of this work, he collected data on the heights of adult children and their parents.

Usage

data(Galton)

Format

A data frame with 898 observations on the following variables.

family: a factor with levels for each family
father: the father's height (in inches)
mother: the mother's height (in inches)
sex: the child's sex: F or M
height: the child's height as an adult (in inches)
nkids: the number of adult children in the family, or, at least, the number whose heights Galton recorded.

Details

Entries were deleted for those children whose heights were not recorded numerically by Galton, who sometimes used entries such as "tall", "short", "idiotic", "deformed" and so on.

Source

The data were transcribed by J.A. Hanley who has published them at http://www.medicine.mcgill.ca/epidemiology/hanley/galton/

Details

Eligible subjects were adults, who spoke Spanish or English, reported alcohol, heroin or cocaine as their first or second drug of choice, resided in proximity to the primary care clinic to which they would be referred or were homeless. Patients with established primary care relationships they planned to continue, significant dementia, specific plans to leave the Boston area that would prevent research participation, failure to provide contact information for tracking purposes, or pregnancy were excluded.

Subjects were interviewed at baseline during their detoxification stay and follow-up interviews were undertaken every 6 months for 2 years. A variety of continuous, count, discrete, and survival time predictors and outcomes were collected at each of these five occasions.

This dataset is a superset of the HELPmiss and HELPrct datasets which include far fewer variables. Full details of the survey instruments are available at the following link.

length: length of longer foot (in cm)
width: width of longer foot (in cm)
sex: a factor with levels B G
biggerfoot: a factor with levels L R
domhand: a factor with levels L R

Details

Quoted from the source: "From a very young age, shoes for boys tend to be wider than shoes for girls. Is this because boys have wider feet, or because it is assumed that girls, even in elementary school, are willing to sacrifice comfort for fashion? To assess the former, a statistician measures kids' feet."

Mites and Wilt Disease

Description

Data from an experiment to test whether exposure to mites protects against Wilt Disease in cotton plants.

Usage

data(Mites)

Format

A data frame with 47 observations on the following variables.

treatment: a factor with levels mites and no mites
outcome: a factor with levels wilt and no wilt

Details

Researchers suspected that attack of a plant by one organism induced resistance to subsequent attack by a different organism. Individually potted cotton plants were randomly allocated to two groups: infestation by spider mites or no infestation. After two weeks the mites were dutifully removed by a conscientious research assistant, and both groups were inoculated with Verticillium, a fungus that causes Wilt disease.

Volume of Users of a 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(RailTrail)

Format

A data frame with 90 observations on the following variables.

hightemp: daily high temperature (in degrees Fahrenheit)
lowtemp: daily low temperature (in degrees Fahrenheit)
avgtemp: average of daily low and daily high temperature (in degrees Fahrenheit)
spring: indicator of whether the season was Spring
summer: indicator of whether the season was Summer
fall: indicator of whether the season was Fall
cloudcover: measure of cloud cover (in oktas)
precip: measure of precipitation (in inches)
volume: estimated number of trail users that day (number of breaks recorded)
weekday: logical indicator of whether the day was a non-holiday weekday
dayType: one of "weekday" or "weekend"

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 is no data for the cold winter months.

Cherry Blossom Race

Description

The Cherry Blossom 10 Mile Run is a road race held in Washington, D.C. in April each year. (The name comes from the famous cherry trees that are in bloom in April in Washington.) The results of this race are published. This data frame contains the results from the 2005 race.

Usage

data(TenMileRace)

Format

A data frame with 8636 observations on the following variables.

state: State of residence of runner.
time: Official time from starting gun to finish line.
net: The recorded time (in seconds) from when the runner crossed the starting line to when the runner crossed the finish line. This is generally less than the official time because of the large number of runners in the race: it takes time to reach the starting line after the gun has gone off.
age: Age of runner in years.
sex: A factor with levels F M.

Examples

data(TenMileRace)
if (require(ggformula)) {
  gf_point(net ~ age | sex, data = TenMileRace, color = ~sex, alpha = 0.1) |>
  gf_density2d(color = "gray40")
