Linear and Nonlinear Methods for Analyzing Daily and Monthly Dendroclimatological Data

Provides novel dendroclimatological methods, primarily used by the Tree-ring research community. There are four core functions. The first one is daily_response(), which finds the optimal sequence of days that are related to one or more tree-ring proxy records. Similar function is daily_response_seascorr(), which implements partial correlations in the analysis of daily response functions. For the enthusiast of monthly data, there is monthly_response() function. The last core function is compare_methods(), which effectively compares several linear and nonlinear regression algorithms on the task of climate reconstruction.


dendroTools 1.0.2.

  • Package version is changed to 1.0.2
  • There have been many issues with RWeka package, which depends on rJava. Therefore, functions from RWeka are replaced with other functions. For random forest model we now use randomForest package
  • There are six new output elements, all of them are residual diagnostic plots for calibration, holdout and edge data.
  • Due to many problems related to rJava in R, MT and BMT methods from RWeka are now joined and replaced by cubist function from Cubist r package. Cubist fits a model tree or ensemble of model trees, if committees argument is more than 1.
