genwhisker
(Package: genasis) :
Box and whisker plot - overview of dataset
Function genwisker allows to draw several box & whisker plots of the dataset. Boxes and whiskers could be drawn for all the data on each pollutant or differentiated by colours over individual years.

genpastoact
(Package: genasis) :
Recalculates adsorption results from passive air samplers to (active-like) concentrations
Function genpastoact provides two different tools for recalculating POPs concentration results from passive air samplers (in mass per filter units) to concentrations (in mass per air volume) comparable with results from active air samples.

genstatistic
(Package: genasis) :
Computes a set of statistics on input data
Function genstatistic computes a set of statistic according to demands on evaluation of Genasis and GMP data.

genanaggr
(Package: genasis) :
Computes annual aggregations from (relevant) POPs concentration data
Function genannagr aggregates (concentration) values over time using selected aggregation function. Aggregation is made for whole years by the middle time points of measurement intervals. If assumptions on number of measurements or their (semi)equidistance are not met, the aggregation is flagged and eventually discarded.

genloq
(Package: genasis) :
Substitution of (concentration) values below a limit of quantification (LoQ)
Function genloq uses given (or determines) threshold of the limit of quantification and substitutes string "LoQ" of values below it.

genranges
(Package: genasis) :
Determines "smooth" range of input data
Function genranges determines suitable lower and upper borders of numeric range covering all values of input vector. Both borders are chosen sutable rounded not to have a lot of decimals.

gendate
(Package: genasis) :
Compile the date of measurement
Function gendate compiles different types of calendar dates and returns vector of class "Date". gendate recognizes single argument x as a vector of class "character", "Date", "POSIXct" or "POSIXlt".

genplot
(Package: genasis) :
Plot of concentration time series
Function genplot allows to draw points of time series of persistent organic pollutant concentration. Several parametric and non-parametric interlacing curves are available and optional (linear and exponential) and three possibilities of drawing confidence interval of the trend line (none, one-coloured and gradient).
