Description Usage Format Author(s) Source References See Also

Weather observations from a number of locations around Australia, obtained from the Australian Commonwealth Bureau of Meteorology and processed to create a sample dataset for illustrating data mining using R and Rattle.

The data has been processed to provide a target variable RainTomorrow (whether there is rain on the following day - No/Yes) and a risk variable RISK_MM (how much rain). Various transformations are performed on the data.

The weather dataset is a fixed subset of the full weatherAUS dataset, for the purpose of repeatable demonstration. It includes only one year of data for a single weather station.

The weatherAUS dataset is ever changing, with each release of Rattle. It is updated from the Bureau of Meteorology web site regularly.

The locationsAUS dataset records the location of each weather station.

1 2	weather weatherAUS

The weather dataset is a data frame containing one year of daily observations from a single weather station (Canberra). The weatherAUS dataset is a data frame containing over 35,000 daily observations from over 45 Australian weather stations.

Date: The date of observation (a Date object).
Location: The common name of the location of the weather station.
MinTemp: The minimum temperature in degrees celsius.
MaxTemp: The maximum temperature in degrees celsius.
Rainfall: The amount of rainfall recorded for the day in mm.
Evaporation: The so-called Class A pan evaporation (mm) in the 24 hours to 9am.
Sunshine: The number of hours of bright sunshine in the day.
WindGustDir: The direction of the strongest wind gust in the 24 hours to midnight.
WindGustSpeed: The speed (km/h) of the strongest wind gust in the 24 hours to midnight.
Temp9am: Temperature (degrees C) at 9am.
RelHumid9am: Relative humidity (percent) at 9am.
Cloud9am: Fraction of sky obscured by cloud at 9am. This is measured in "oktas", which are a unit of eigths. It records how many eigths of the sky are obscured by cloud. A 0 measure indicates completely clear sky whilst an 8 indicates that it is completely overcast.
WindSpeed9am: Wind speed (km/hr) averaged over 10 minutes prior to 9am.
Pressure9am: Atmospheric pressure (hpa) reduced to mean sea level at 9am.
Temp3pm: Temperature (degrees C) at 3pm.
RelHumid3pm: Relative humidity (percent) at 3pm.
Cloud3pm: Fraction of sky obscured by cloud (in "oktas": eighths) at 3pm. See Cload9am for a description of the values.
WindSpeed3pm: Wind speed (km/hr) averaged over 10 minutes prior to 3pm.
Pressure3pm: Atmospheric pressure (hpa) reduced to mean sea level at 3pm.
ChangeTemp: Change in temperature.
ChangeTempDir: Direction of change in temperature.
ChangeTempMag: Magnitude of change in temperature.
ChangeWindDirect: Direction of wind change.
MaxWindPeriod: Period of maximum wind.
RainToday: Integer: 1 if precipitation (mm) in the 24 hours to 9am exceeds 1mm, otherwise 0.
TempRange: Difference between minimum and maximum temperatures (degrees C) in the 24 hours to 9am.
PressureChange: Change in pressure.
RISK_MM: The amount of rain. A kind of measure of the "risk".
RainTomorrow: The target variable. Did it rain tomorrow?
