in addition to "mean", also "median", "min", "max" and "sd" can be applied * plotAvailability: faster plotting * profile: new method loglm (log-linear model) added - now more than two heights can be used for profile calculation bReeze 0.2-2 [2013-06-27] ------------------------- * availability: v.set and dir.set can now handle vectors of datasets * availability, clean, frequency, monthStats, plotAvailability, plotDay, plotMonthStats, plotTimeSeries, plotTurbIEC,profile, turbulence, weibull: data sets can now be specified by name * formatTS: bug fixed - handling of duplicates * plotPC: bug fixed - ugly axis if both coefficients are plotted; a list of power curves can now be plotted at once * printObject: bugs fixed - function calls incorrect in some cases * readPC: power curve data base update * new short name aliases for functions bReeze 0.2-1 [2013-02-28] ------------------------- * energy, frequency and plotProfile: bug fixed - output of internally called function printed * frequency, profile, turbulence, weibull: number of sectors no longer limited to 4/8/12/16 * monthStats: bug fixed - calculation error for met masts with just one dataset * printObject: bug fixed - original/cleaned data displayed wrong for met masts with just one dataset * polar plotting functions (plotAep, plotEnergy, plotFrequency, plotPolar, plotTurbulence): optional graphical parameters added * some small code and documentation cosmetics bReeze 0.2-0 [2013-02-06] ------------------------- * clean: wind direction values are now excluded, where wind speed is lower than the v.avg.min specified; bug fixed - unwanted cleanings and wrong feedback possible; repetitions can now be cleaned * frequency: bug fixed - wrong frequency values possible for uncleaned mast objects * plotDay: now all signals can be plottet * plotMap: function removed from package due to disproportional high installation requirements compared to the low performance of the used OpenStreetMap package * printMast: replaced by printObject * printObject: new print method for all bReeze objects; bug fixed in old printMast method, that returned wrong availability values * plotting functions (plotAep, plotAvailability, plotDay, plotEnergy, plotFrequency, plotMonthStats, plotPC, plotPolar, plotProfile, plotTimeSeries, plotTurbIEC, plotTurbulence, plotWbDir, plotWeibull): many optional graphical parameters added * processing functions (aep, energy, frequency, monthStats, profile, turbulence, weibull): new 'digits' argument for the number of decimal places to be used for results; new 'print' argument to show/hide results * further small improvements of code and documentation; namespace added bReeze 0.1-1 [2012-10-21] ------------------------- * aep: capacity factor added to the output * availability: two bugs fixed - slightly wrong availability values in some cases of missing samples; error in calculation for sets with just one signal * clean: wind speed limit for calculation of turbulence intensity can now be adjusted by the user * createPC: if rated.p is not given, rated power is now automatically set to the maximum power value;
