Breaking changes
hist() now produces a single histogram.
nexus 0.3.0 (2024-09-03)
New classes and methods
- Add transformation methods for
LogRatio objects (clr <-> alr, clr -> ilr, alr -> ilr).
- Add
condense() to compute compositional mean of data subsets.
- Add
pip() to compute proportionality index of parts.
- Add
rbind() method for CompositionMatrix objects.
- Add
show() methods for LogRatio objects.
- Add
is_element_major(), is_element_minor(), is_element_trace() and is_oxide() methods for CompositionMatrix objects.
- Add
variance() and variance_total() to compute (total) variance.
Enhancements
- Add example datasets.
- Improve bar chart rendering.
Bugfixes & changes
- Fix
pca() for LogRatio objects (default arguments were not passed to the internal method).
Internals
- Store groups as
factor instead of character.
Breaking changes
[ always returns a CompositionMatrix object by default, even if only one row/column is accessed.- Remove
samples slot in all classes.
- Remove
as_features().
- Remove
metrix_var() and metric_sd().
- Remove the
base argument of transform_ilr().
- Rename
get_totals() and set_totals() to totals().
- Rename
get_groups() and get_groups() to groups().
- Rename
outliers() to detect_outlier() and redefine methods.
- Rewrite
plot() method for OutlierIndex object.
nexus 0.2.0 (2024-02-26)
New classes and methods
- Add
hist() methods to plot ILR histograms.
- Add
quantile() methods for compositional data matrix.
- Add
split() methods to divide into groups.
Enhancements
transform_ilr() gained a new argument allowing the specify the base of the transformation.barplot() gained a new argument to display a legend.
Internals
- List dimensio in
