assignR news

assignR 2.4.3

• Bug fixes and enhanced error checking
• Requires R >= 4.0

assignR 2.4.1

• Single site can be provided in wDist and will be recycled with a message
• wDist allows specification of bandwidth for kernel density estimation
• Bug fixes

assignR 2.4.0

• Updates and fixes in the knownOrig database (v 0.2)
• Added download of global bioavailable Sr and USA groundwater H and O isotopes in getIsoscapes
• Bug fixes

assignR 2.3.0

• Transitioned spatial dependencies to terra package; all functions still accept raster and sp objects for backward compatibility, but users are encouraged to move their workflows to terra
• Instituted versioning of the knownOrig database (v 0.1)
• Performance improvements for large QA jobs
• Bug fixes

assignR 2.2.3

• Bug fixes

assignR 2.2.2

• Updated error handling in getIsoscapes

assignR 2.2.1

• Remove data from projects 14 and 15 from knownOrig dataset

assignR 2.2.0

• Add wDist function and c and plot methods for summarizing weighted distance and bearing distributions using sample collection locations and posterior probability maps
• QA option to run without iterative recalibration of isoscape
• Bug fixes
• Documentation edits

assignR 2.1.1

• Bug fixes

assignR 2.1.0

• Add isoStack function to stack multiple isoscapes in a single data object; added plot s3 method for this class
• Add getIsoscape function supporting download of gridded isotope maps; removed global precipitation maps previously distributed with package
• Update pdRaster and QA to support multivariate analysis
• Add option to include spatial prior in QA
• Bug fixes

assignR 2.0.0

• knownOrig database has been expanded and reformatted
• New data objects document different calibration standards used to generate known-origin H and O isotope data
• subOrigData supports transformation of data among different calibration standard scales using the ‘standard-chain’ method of Magozzi et al. (in press); format of return object from this function has changed
• calRaster changes including new format for input object “known” and use of weighted least squares regression; tissue isoscape variance calculation updated to a + b - c, where a is isoscape grid cell variance, b is the residual variance of tissue predictions made from isoscape-tissue rescaling functions fit using values sampled from the isoscape with noise, and c is the variance of the sampled isoscape values
• QA changes including new format for input object “known” and option to resample known data by site rather than by sample; for bySite option returned results are the average of site-level average statistics; argument order changed for consistency with calRaster
• sp objects updated to support WKT2_2019 strings

assignR 1.2.1

• Updates to ensure compatibility with new CRS specifications in rgdal
• QA now accepts optional argument “by”, allowing reduced run-time

assignR 1.2.0

• NAMESPACE imports required functions only
• Implemented testthat testing
• Minor corrections to knownOrig data
• Minor enhancements and bug fixes

assignR 1.1.3.1

• Data update: remove plover maps, add US states

assignR 1.1.3

• Shorter run-time for vignette examples

assignR 1.1.2

• Functional examples for QA
• Improved handling of graphical parameters in plotting functions
• Bug fixes

assignR 1.1.1

• Consistent syntax for saving output to disk, which requires explicit specification of directory
• Improved messaging from functions
• Bug fixes

assignR 1.1

• Propagation of error covariance in isoscape and rescaling models removes source of bias in posterior probabilities
• plot.QA converted to S3 method
• Bug and code fixes to pass CRAN check

assignR 1.0
