goeveg 0.7.5 (2024-05-17)

• Added argument to define number of decimal places in 'syntable()'-results
• Empty cell values are transformed to 0 in 'clean_matrix()'
• Fixed 'clean_matrix()' to work correctly with non-numeric values in data tables

goeveg 0.7.4 (2024-02-26)

• Added option to transform with individual scales per sample in 'cov2per' and 'per2cov'
• Added descriptions and option 'rmchar' to 'trans_matrix()'

goeveg 0.7.3

• Added function 'clean_matrix()' to remove species without occurrences (frequency = 0) and samples without species from a species matrix in one simple step
• Added function 'trans_matrix()' to transpose a species matrix, while preserving correct species and sample names.
• Simplified function 'merge_taxa()' to make it work much faster.
  • Added option 'backtransform' to decide whether cover-abundance values should be kept as percentage cover or back-transformed into original cover-abundance values
  • Option 'drop_zero' renamed to 'clean_matrix' and set on FALSE by default
• Fixed an error in 'cov2per' when providing a data frame with only one column as community data
• Fixed an unnecessary warning message in 'syntable' occurring at cover value transformation

goeveg 0.7.2 (2024-02-06)

• Added cover abundance scale "niwap" from Lower Saxony species survey programmes (Schacherer 2001)
• Added 'x'-value to presence/absence scale
• 'merge_taxa()':
  • returns names of merged taxa only once (not for each relevé)
  • added option 'drop_zero' to decide whether species without occurrences or empty samples should be removed or kept
  • fixed an error when providing individual scales for each sample
• 'syntable()' and 'merge_taxa()' automatically repair imported tables with empty character values ("")

goeveg 0.7.1 (2023-12-13)

• 'syntable()' can now handle factorial variables for defining clusters, e.g. to summarize relevés according to pre-defined categories and is more flexible regarding the format of the community matrix
• Terminology was harmonized between different functions

goeveg 0.7.0

• New functions added:
  • 'merge_taxa()' for merging taxa/species with identical names
  • 'cov2per()' and 'per2cov()' for conversion between cover-abundance codes and percentage cover
• 'dimcheckMDS()' is renamed into 'screeplot_NMDS()' with enhanced description and progress bar

goeveg 0.6.5 (2023-06-13)

• Fixed wrong species labeling in 'racurve()' when 'freq = TRUE'

goeveg 0.6.4 (2023-05-16)

• Added functions 'deg2rad()' and 'rad2deg()' for conversion between radians and degrees
• Updated data table 'schedenenv'

goeveg 0.6.3

• Fixed wrong p-value calculation for GLMs in 'specresponse()'
• Fixed problem with NAs in 'specresponse()' when showing point values

goeveg 0.6.2

• Added na.action argument to 'specresponse()'

goeveg 0.6.1 (2023-05-04)

• Explained deviances and p-values are now printed in 'specresponse()'. Full model results are returned in an (invisible) object.
• Added functionality to select the least abundant (rarest) species in 'ordiselect()'

goeveg 0.6.0 (2023-04-19)

• (Re-)added functions for calculation and sorting of synoptic tables: 'syntable()' and 'synsort()'
• Comprehensive update for 'ordiselect()'. Now returns exact proportion of selected species. Correction in selection to axis fit limits. Variable fit now only works with factor centroids.
• Updated help pages

goeveg 0.5.1 (2021-05-10)

• Fixes in references and value tags

goeveg 0.5.0

• Removal of functions 'synsort()' and 'syntable()' due to unsolved incompatibilities

goeveg 0.4.4

• Added lwd argument for 'specresponse()'

goeveg 0.4.3

• Added xlim & ylim arguments for 'racurve()'
• Added na.rm argument for 'ordiselect()'

goeveg 0.4.2 (2018-11-22)

• Small fixes, fixed package dependencies
• Spell checking

goeveg 0.4.1

• Added new functions for calculation and sorting of synoptic tables: 'syntable()' and 'synsort()'

goeveg 0.3.3 (2017-01-25)

• Fixes in documentation

goeveg 0.3.2

• Merged 'specresponses()'/'specresponse()' into one single function 'specresponse()'
• Better selection method of polynomial GLMs and GAMs in 'specresponse()'

goeveg 0.3.1

• Fixed use of external functions ('gam()', 'rdist()')
• Max. of 3 polynomials in automatic GLM selection of 'specresponse()'

goeveg 0.3.0 (2016-12-14)

• Fixed and renewed function 'specresponse()'/'specresponses()': now works also with NMDS, includes zero values and is based on presence/absence data (logistic regression). Instead of cubic smoothing splines the function now uses GLMs/GAMs.

goeveg 0.2.0 (2016-06-21)

• Added functionality to use frequencies in 'racurve()'
• Added functionality to label species in 'racurve()'
