nexus 0.3.0
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.
