<i class="fas fa-envelope-open-text"></i> biomod 4.2-6 - Improved OptionsBigBoss and new model

<i class="fas fa-exclamation-triangle"></i> Please feel free to indicate if you notice some strange new behaviors !

<i class="fas fa-exchange-alt"></i> What is changed ?

• To improve the models, we made some change in the options for OptionsBigboss. (This only affects the ANN, CTA and RF models.) You can check all your options with the get_options() function.
• To reduce the tuning calculation time, we update the tuning ranges for ANN, FDA and MARS models.

<i class="fas fa-plus-square"></i> What is new ?

• biomod2 has a new model: RFd. It's a Random Forest model with a down-sampling method.
• You can now define seed.val for bm_PseudoAbsences() and BIOMOD_FormatingData().
• New fact.aggr argument, for pseudo-absences selection with the random and disk methods, allows to reduce the resolution of the environment.
• Possibility to give the same options for all datasets with "for_all_datasets" in bm_ModelingOptions().

<i class="fas fa-envelope"></i> biomod 4.2-5 - Modeling options & Tuning Update

<i class="fas fa-exchange-alt"></i> What is changed ?

• modeling options are now automatically retrieved from single models functions, normally allowing the use of all arguments taken into account by these functions
• tuning has been cleaned up, but keep in mind that it is still a quite long running process
• in consequence, BIOMOD_ModelingOptions and BIOMOD_Tuning functions become secondary functions (bm_ModelingOptions and bm_Tuning), and modeling options can be directly built through BIOMOD_Modeling function

<i class="fas fa-plus-square"></i> What is new ?

• ModelsTable and OptionsBigboss datasets (note that improvement of bigboss modeling options is planned in near future)
• 3 new vignettes have been created :
  • data preparation (questions you should ask yourself before modeling)
  • cross-validation (to prepare your own calibration / validation datasets)
  • modeling options (to help you navigate through the new way of parametrizing single models)

<i class="fas fa-envelope"></i> biomod 4.2 - Terra Update

<i class="fas fa-exchange-alt"></i> What is changed ?

• biomod2 now relies on the new terra package that aims at replacing rasterand sp.
• biomod2 is still compatible with old format such as RasterStackand SpatialPointsDataFrame.
• biomod2 function will sometimes return SpatRaster from package terra that you can always convert into RasterStack using function stack in raster.

<br/><br/>

<i class="fas fa-envelope"></i> biomod 4.1 is now available

/!\ Package fresh start... meaning some changes in function names and parameters. We apologize for the trouble >{o.o}< <br/> Sorry for the inconvenience, and please feel free to indicate if you notice some strange new behaviors !

<i class="fas fa-exchange-alt"></i> What is changed ?

• all code functions have been cleaned, and old / unused functions have been removed
• function names have been standardized (BIOMOD_ for main functions, bm_ for secondary functions)
• parameter names have been standardized (same typo, same names for similar parameters across functions)
• all documentation and examples have been cleaned up

<i class="fas fa-plus-square"></i> What is new ?

• plot functions have been re-written with ggplot2
• biomod2 website has been created, with proper roxygen2 documentation and help vignettes

<i class="fas fa-question-circle"></i> But... why ?

• “For every minute spent on organizing, an hour is earned.” — Benjamin Franklin
  • better documentation, better formation, better help provided
  • new improvements to come (update of single models, implementation of abundance models, etc)
