stratigraphr 0.5.0
-
stratigraph() supports tidy/long-format data frames where each row represents a single relation (#15)
- Improved validation workflow for stratigraphs
- Validation now considers redundant relations.
-
strat_is_valid() renamed to strg_is_valid() (#21) and silently returns a logical value.
- Use
strg_validate() to raise an error for invalid stratigraphs or strg_validate(warn = TRUE) to raise a warning.
- Adds
print() method for stratigraphs including validations status
- Minimum supported R version is now 4.1
- Removes deprecated
c14_* and cal_* functions. These now live in the c14 package.
- Removes
shub1_radiocarbon dataset (also now found in c14)
- Adds dependencies on vctrs and vroom
- Drops dependencies on rcarbon, magrittr, tidyr, Bchron (suggested) and ggplot2 (suggested)
- Downgrades dependencies on tibble, dplyr and readr to suggested
stratigraphr 0.4.0
-
strg_prune() implements transitive reduction of stratigraphic graphs (#13)
-
strg_locate_cycles() locates cycles in stratigraphic graphs (#3)
- Radiocarbon-related functions (
c14_* and cal_*) have been moved to the c14 package. The legacy versions in this package will issue a deprecation warning until the next version, when they will be removed.
- Removes fs dependency – replaced with base R functions (#16)
- Removes tidyselect dependency
- ggplot2 and ggraph moved to suggested dependencies
stratigraphr 0.3.0
- Expanded framework for tidy radiocarbon analysis, adding:
- New S3 object
cal, a generic representation of calibrated probability distributions
- Methods for printing and summarising
cal objects
- Type conversion functions for
cal objects (as_cal.CalDates(), as_cal.oxcAARCalibratedDatesList() and as_cal.BchronCalibratedDates())
- New
vignette("tidy_radiocarbon")
-
Breaking change:
cal() and sum() renamed c14_calibrate and c14_sum and now return cal objects.
-
Breaking changes to
stratigraph interface:
- Renamed functions:
harris() → strat_connect(), is_valid_harris() → strat_is_valid()
- Removed the notion of a “type” of
stratigraph().
-
stratigraph() will now return a graph even if it is not stratigraphically valid.
- Renamed
vignette("harris") → vignette("stratigraph")
- Expanded the
stratigraph interface, adding:
- Fixed read_lst() when reading Stratify ‘extended’ LST files
- Added a
NEWS.md file to track changes to the package.
stratigraphr 0.2.0
Initial alpha release, including:
- Functions for constructing stratigraphic graphs
- Simple tidy wrappers for the rcarbon package
- Partial CQL interface
