openair 2.3-99

  • add option plot to TheilSen. FALSE can be useful when analysing data to extract the trend components and plot in otherways and when the TheilSen plot is not required.
  • add option silent to TheilSen to avoid printing updates to trend fitting. By default it is FALSE.
  • fix wrong ordering of names in timeVariation when more than one pollutant
  • fix date parsing issues in selectByDate.
  • fix wrong ordering in timePlot

openair 2.2-3

Main changes

  • refine selectByDate due to changes in lubridate
  • fix issue with importSAQN when no data
  • remove site information from help of importAURN and point users to importMeta

  • fix regression when fitting smooth using trajLevel
  • remove all Airbase functions, will be available via new package that also incorporates newer e-reporting data
  • fix bug in timeAverage when statistic = "sum" and all data in period was missing (would return 0 rather than NA)
  • make sure that same data used in all conditionalEval plots by using data where there are no missing data for all variables used. This is more important of var.obs and var.mod are supplied and hence additional variables are considered relative to only obs and mod.
  • fix date issues in calendarPlot to do with time zones
  • remove missing data when type is a numeric value split up into quantiles
  • fix bug in windRose/pollutionRose when two conditioning variables were given (problem in bias correction)

  • warn when >10% negative data detected in polarPlot and suggest setting force.postive = FALSE
  • make maps Suggests rather than Depends
  • refine check on whether bias correction is needed in windRose
  • still plot data when <6 points in TheilSen and when no trend information is given
  • New function binData to easily summarise mean and 95% confidence intervals for intervals of a variable

  • Do not run checkPreo on selectByDate because it removes calms
  • Fixed scaling bug in polarFreq when ws.int != 1
  • use avg.time in calcPercentile instead of 'period' to ensure consistency with other functions (timePlot would fail with percentiles)
  • return NA in aqStats when no data present; previously it tried to calculate quanities, returning -Inf etc

openair 0.4-17

  • use readRDS and not .readRDS (caused failure on R Dev)
  • openair now depends on >=R2.13.0
  • NEW FUNCTION sqStats to calculate common and pollutant-specfic air quality statsitics by year and site.
  • Changed option data.capture in rollingMean to data.thresh to be consistent with other functions.

openair 0.4-16

  • Fixed bugs in cutData when a partial year was used with type = "month". Also affected type = "season" and "weekday". The plots were labelled in the wrong order.
  • Ensure that missing wind sectors are skipped in type = "wd" for smoothTrend, MannKendall, timePlot and scatterPlot

openair 0.4-15

  • Preparation for CRAN release
  • removed some restrictions on type/period combinations in polarAnnulus

openair 0.4-14

  • Added preliminary greyscale method to openColours and linked in strip background and other text and line colour control for standard openair plots.

openair 0.4-13

  • Removed ad-hoc sites from importKCL, added site classification to the help file and ensured GMT is exported.

openair 0.4-12

  • Added y.relation option to smoothTrend and MannKendall to allow flexible y-scales.
  • NEW FUNCTION 'percentileRose' for flexible plotting of percentiles by wind direction
  • NEW FUNCTION selectRunning for selecting run lengths of a numeric variable above a certain threshold.
  • Modified plot layout in polarPlot to maximise plotting area
  • Initial fixes to functions affected by time zone settings
  • polarFreq now has consistent annotation cf. windRose and percentileRose; new option grid.line to control radial axes.
  • Fixed couple of minor auto.text bugs in summaryPlot and timePlot
  • Removed dependency of date for polar functions where time-based types are not required.

openair 0.4-11

  • More consistent use of strips in default plot (remove them)
  • Add percentage units to windRose and pollutionRose on radial scale

openair 0.4-10

  • Fixed calendarPlot main/quickText handling.
  • Fixed calendarPlot first day of month error.
  • Fixed summaryPlot site ordering when more than one site.

openair 0.4-9

  • Added new options to scatterPlot (plot.type, lwd, and lty) making it possible to add points and/or lines

openair 0.4-8

  • Added new cutData type option 'daylight', enabled using new function cutDaylight.

openair 0.4-7

  • Added new function conditionalQuantile for model
evaluation purposes.

  • Fixed `importAURN` to account for a change in web domain
address at AEA.
