# Sample dataset of daily weather observations from Canberra airport in Australia. One year of daily weather observations collected from the Canberra airport in Australia was obtained from the Australian Commonwealth Bureau of Meteorology and processed to create this sample dataset for illustrating data mining using R and Rattle. data ## Format A data frame of 354 observations of 20 variables. One year of daily observations of weather variables at Canberra airport in Australia between November 1, 2007 and October 31, 2008. * Date, The date of observation (Date class). * 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 "Class A pan evaporation" (mm) in the 24 hours to 9am. * WindSpeed3pm, Wind speed (km/hr) averaged over 10 minutes prior to 3pm. * Humid9am, Relative humidity (percent) at 9am. * Humid3pm, Relative humidity (percent) at 3pm. * Pressure9am, Atmospheric pressure (hpa) reduced to mean sea level at 9am. * Pressure3pm, Atmospheric pressure (hpa) reduced to mean sea level at 3pm. * Cloud9am, Fraction of sky obscured by cloud at 9am. This is measured in "oktas", which are a unit of eighths. It records how many eighths of the sky are obscured by cloud. A 0 measure indicates completely clear sky whilst an 8 indicates that it is completely overcast. * Cloud3pm, Fraction of sky obscured by cloud (in "oktas": eighths) at 3pm. See Cloud9am for a description of the values. * Temp9am, Temperature (degrees C) at 9am. * Temp3pm, Temperature (degrees C) at 3pm. * RISK_MM, The amount of rain. A kind of measure of the "risk". * RainToday, Factor: "yes" if precipitation (mm) in the 24 hours to 9am exceeds 1mm, otherwise 0. * RainTomorrow, Factor: "yes" if it rained the following day, the target variable.

Various transformations were performed on the source data. The dataset is quite small and is useful only for repeatable demonstration of various data science operations. This is a cleaned subset of `rattle::weather`. Replicating this dataset: ``` require("rattle") d <- rattle::weather[, c(1, 3:7, 9, 12:21, 23, 22, 24)] d <- d[complete.cases(d), ] ## Remove ~12 row-wise incomplete rows d <- as.data.frame(d) ## Remove tibble dependency weather_na.rm <- d ## save(weather_na.rm, file = "./data/weather_na.rm.rda") ``` ## Examples ```r library(spinifex) str(weather_na.rm) dat <- scale_sd(weather_na.rm[, 2:18]) clas <- weather_na.rm$RainTomorrow bas <- basis_pca(dat) mv <- manip_var_of(bas) mt <- manual_tour(bas, mv) ggt <- ggtour(mt, dat, angle = .2) + proto_default(aes_args = list(color = clas, shape = clas)) animate_plotly(ggt) ```
