Bioclimatic indicators

Hi @erifarov,

@allabres has been working with bioclimatic indicators. Below you can see the list of the functions we will use to write a vignette. We will need three new functions: PeriodMax(), PeriodMin() and PeriodVariance(). They should be almost the same as the current PeriodMean() function.

Do you think you could develop these three functions?

This is not urgent, but we would like to keep improving the package and use this in the future.

Once these functions are done, we will work on a vignette.

Are you happy with this plan?

We can have a meeting if necessary.

Kind regards,

Alba & Núria

FYI @rmarcos

BIO1 = Annual Mean Temperature --> PeriodMean()
BIO2 = Mean Diurnal Range (Mean of monthly (max temp - min temp)) --> PeriodMean()
BIO3 = Isothermality (BIO2/BIO7) (×100) --> vignette
BIO4 = Temperature Seasonality (standard deviation ×100) --> NEW PeriodVariance (?)
BIO5 = Max Temperature of Warmest Month --> NEW PeriodMax() (?)
BIO6 = Min Temperature of Coldest Month --> NEW PeriodMin() (?)
BIO7 = Temperature Annual Range (BIO5-BIO6) --> vignette
BIO8 = Mean Temperature of Wettest Quarter --> PeriodAccumulation to know the wettest period and PeriodMean(using wettest period) (? Doubtful for seasonal forecast)
BIO9 = Mean Temperature of Driest Quarter --> same as BI08
BIO10 = Mean Temperature of Warmest Quarter --> same as BI08
BIO11 = Mean Temperature of Coldest Quarter --> same as BI08
BIO12 = Annual Precipitation -> PeriodAccumulation
BIO13 = Precipitation of Wettest Month --> PeriodMax()
BIO14 = Precipitation of Driest Month --> PeriodMin()
BIO15 = Precipitation Seasonality (Coefficient of Variation) --> ABOVE NEW sqrt(PeriodVariance) / PeriodMean
BIO16 = Precipitation of Wettest Quarter -> PeriodAccumulation()
BIO17 = Precipitation of Driest Quarter --> PeriodAccumulation()
BIO18 = Precipitation of Warmest Quarter --> PeriodAccumulation() 
BIO19 = Precipitation of Coldest Quarter --> PeriodAccumulation()
