WARNING
Following the recent update of the htmlwidgets package, problems have been observed in the use of dynamic graphics and in the graphical interface of the airGRteaching package (in fact due to the use of the dygraphs package).
After installing the airGRteaching packages, which will install the latest version of htmlwidgets available on CRAN (version 1.5.1), you will must therefore install the latest version available on GitHub.
How to manage

0.2.8.69 Release Notes (2020-02-28)

New features

• added as.data.frame.airGRt() method in order to create a data.frame from outputs of PrepGR(), CalGR() and SimGR() functions. This data.frame always presents the same structure and contains observed flow, simulated flow, simulated solid precipitation fraction, etc. When it does not make sense, the concerned column is assigned with NA values (e.g. Qsim with the PrepGR() function)

• a digital object identifier (DOI) now allows to identify the manual of the ‘airGRteaching’ package. When you use airGRteaching in your work, please always cite both the article and the manual. The last one allows to know the version of the package that is used in order to enhance reproducible research. The references can be displayed with the citation(“airGRteaching”) command

• two themes of alternative stylesheet are available (“Inrae” and “Saclay”)

Deprecated and defunct

• The CalGR argument is now deprecated in the SimGR() function. It has been replaced by the use of the Param argument which can be set by an object of the class CalGR or by a vector of parameters

Bug fixes

• ShinyGR() now runs when independent arguments (DatesR, Precip, etc.) are used instead of the ObsDF argument

User-visible changes

• it is now possible to use the GR4H and GR5H hourly models with or without CemaNeige. For that, in the PrepGR(), the HydroModel argument could be set to “GR4H” or “GR5H”. In the GUI, launched by ShinyGR() function, nothing changed, only the daily models are available. So, now airGRteaching depends on the version of airGR >= 1.4.3.52)

• it is now possible to run the PrepGR() function when discharge is not provided in Qobs. If it is the case, the CalGR() function will return an error message because it is not possible to calibrate the model. The SimGR() function will return a warning message because it is not possible to compute any efficiency criterion

• it is now possible to run the ShinyGR() function when discharge is not provided in Qobs

• when observed discharge is provided in ShinyGR(), the first plotting panel now draws the flow error time series

• the plot() function is now exported

• the dyplot.PrepGR(), dyplot.CalGR() and dyplot.SimGR() functions are no longer exported

• there is now only one help page for all plot.*() functions (use ?plot to call it)

• when the package is loaded, a message warns the users if they use a version of ‘htmlwidgets’ < 1.5.1.9000. The latest version of this package, available on GitHub, avoids troubles with the use of dynamic graphics of the ‘dygraphs’ package (called by the dyplot*() and the ShinyGR() functions)

0.2.6.29 Release Notes (2019-05-02)

Bug fixes

• ShinyGR() can export the csv table again. It was broken due to modifications to the version 1.2.13.16 of the ‘airGR’ package

0.2.6.27 Release Notes (2019-04-23)

Bug fixes

• ShinyGR() takes into account the fact that the previous simulation could have a missing value criterion

• ShinyGR() takes into account the fact the prevuous Qsim is sometimes to long of one value (temporary patch)

User-visible changes

• The WarmUp element returned by CalGR() and SimGR() now presents a timezone defined as UTC

0.2.6.14 Release Notes (2019-04-03)
