dendroTools 1.2.16

• Added new quantile-probability arguments:
  • quantile_prob for daily_response() and monthly_response()
  • quantile_prob_env_data_primary and quantile_prob_env_data_control for daily_response_seascorr() and monthly_response_seascorr()
• This allows analyses based on lower or upper climate extremes, for example the 5th, 90th, or 95th percentile of temperature, precipitation, or other environmental variables within the selected time window.
• Extended previous-year analyses in daily_response(), daily_response_seascorr(), monthly_response(), and monthly_response_seascorr().
• Added the new argument number_previous_years, which allows users to include more than one previous year in response-function analyses.
• Users can now analyse climate windows spanning up to five previous years plus the current year.
• The argument previous_year now acts as the main switch for previous-year analyses. If previous_year = FALSE, previous-year settings are ignored and the analysis is performed for the current year only.
• If negative values are supplied in day_interval or month_interval while previous_year = FALSE, the interval is ignored with a warning and the analysis is performed for the current year only.
• Updated plotting methods to support multi-year climate windows. Heatmaps and extreme-value plots now show relative-year labels such as Y-3, Y-2, Y-1, and Y, with year separators where appropriate.
• Updated x-axis labels in response-function plots to indicate whether the reference position is the start, end, or middle of the analysed window.
• Updated summary methods so that optimal windows from multi-year analyses are reported with the correct relative year.
• Improved robustness of the brnn method. Occasional unstable BRNN model fits are now handled more safely, returning NA for failed windows instead of interrupting the full analysis.
• Improved BRNN cross-validation handling so that failed folds return correctly structured missing-value outputs.
• Updated documentation and examples to demonstrate the new quantile aggregation option and the extended previous-year functionality.

dendroTools 1.2.15

• there was a minor bug in sd(), which returned NA in case of missing values in climate data. This is now corrected and users are informed about the missing values with specific warning

dendroTools 1.2.14

• there was a minor bug in aggregating climate-data when creatng the dataset for optimized_return
• Authors@R field was added to DESCRIPTION

dendroTools 1.2.13

dendroTools 1.2.12

• PCA option is removed from the daily_response and other similar functions
• plot specific options is also removed
• New climate detrending option is implemented, ‘SLD’, which stands for ‘Simple Linear Detrending’ and should be preferred
• Two new arguments are implemented, ‘skip_window_position’ and ‘skip_window_length’ which allow for controlling the granularity of the analysis and can help in reducing computation time by focusing on a subset of the data
• Spline detrending is now removed since it caused instability of the dendroTools package

dendroTools 1.2.11

• response data frame can now also have a missing value, but only if “cor_na_use” argument is one of “complete.obs”, “na.or.complete” or “pairwise.complete.obs”
• an undocumented argument in internal function is now removed

dendroTools 1.2.10

• A bug in some special cases for the reference window “end” is now removed
• In case of no significant correlations, daily_response() now returns a warning rather than error

dendroTools 1.2.9

• new options for the aggregate function - minimum and maximum
• additional feature on reference_window in the monthly_response() and monthly_response_seascorr()

dendroTools 1.2.8

• daily_response() default remove_insignificant argument is set to FALSE
• updated description
• default method in daily_response() and monthly_response() is set to ‘cor’
• corrected all spelling errors

dendroTools 1.2.7

• comments are added to the code, which is now more readable
• unused part of the scripts are removed
• new arguments are implemented to control the behavior of calculations of correlation coefficients in case of missing values
• the calculation of significance of partial correlation coefficients is improved
• daily_transform() is also improved, so it gives the correct behavior in case of missing values

dendroTools 1.2.6

• detrending climate data is now available in all response type functions

dendroTools 1.2.4

• updated vignettes
• new arguments are added which can be used to detrend climate
• climate detrending is based on the dplR R package
• gridExtra is removed from dependences

dendroTools 1.2.1

• Minor correction for ggplot2 object -> guide = FALSE –> guide = ‘none’

dendroTools 1.2.0

• There is a major upgrade related to new arguments that now allow you to specify the time of interest to be used for calculating correlation coefficients or other statistical metrics. For example, if you are using daily_response() or daily_response_seascorr() and want to calculate correlations only from the beginning of last October to the current end of September, use the argument daily_interval =c(-274, 273). Note that a negative sign indicates the previous year’s doy, while a positive sign indicates the current year doy. In normal (non-leap ) years, October 1 represents doy 274, and September 30 represents doy 273.
• If you use monthly_response() or monthly_response_seascorr() and want to calculate correlations only from the beginning of the previous October to the current end of September, for example, use the argument monthly_interval =c(-10, 9). Note that a negative sign indicates the month of the previous year, while a positive sign indicates the month of the current year. Other functions have been changed only slightly, so they will work even if new arguments are used.

dendroTools 1.1.4

• new error is implemented in case of wrong subset_years
• minor corrections to partial correlation functions

dendroTools 1.1.3
