fmesher 0.2.0

New methods

• Add print methods for fm_basis and fm_evaluator objects (version 0.1.7.9003)
• Add fm_manifold_get() generic method to extract manifold information from general objects, so that external objects can implement their own manifold information storage (version 0.1.7.9005)
• Add fm_crs_plot() method for plotting fm_crs objects with optional graticules and Tissot indicatrices (version 0.1.7.9010)

New method options

• Add full argument to fm_basis() to toggle between matrix and full fm_basis object output (version 0.1.7.9002)
• Add loc plotting option to geom_fm.fm_mesh_2d and modify the ggplot mapping interface for interior and boundary segments in the same method (version 0.1.7.9009)
• Add format="loc" argument to fm_as_sfc.fm_mesh_2d() for converting mesh node coordinates to sfc_POINT format (version 0.1.7.9009)

Minor updates

• Update documentation and vector coordinate inputs to fm_lattice_2d() to clarify input interpretation and ensure correct boundary orientation (version 0.1.7.9001)
• Add some length unit handling to fm_crs_bounds() (version 0.1.7.9008)
• Add control argument max_batch_size to fm_bary.fm_mesh_2d(), that can be supplied via fm_basis(), for optional override of the default maximal batch calculation size, see #14 (version 0.1.7.9011)

Deprecation updates

• Remove sp objects from fmexample data. Use fmexample_sp() to access them if needed (version 0.1.7.9004)
• Move sp dependency to Suggests, and remove inlabru dependency (version 0.1.7.9006)
• Further sp use protection (version 0.1.7.9007)
• Increased deprecation warning and error messages for old unsupported methods

fmesher 0.1.7

• Fix regression bug in fm_manifold() that made it ignore all but the first given type options. See #16 (version `0.1.6.9001)
• Fix plot.fm_mesh_2d vectorisation bug (version 0.1.6.9002)
• Add new fm_subdivide() method for fm_mesh_2d meshes (version 0.1.6.9003)

fmesher 0.1.6

• Fix for hiding away-facing triangle edges in plot.fm_mesh_2d() and lines.fm_segm().
• Fix duplicated fm_unify_coords.sf() method. Thanks to Pablo Paccioretti for debugging and reporting, see #13 (version 0.1.5.9001)
• Use batched fm_bary.fm_mesh_2d() computations for data sizes of 2e5 and upwards. This improves performance of fm_basis()/inla.spde.make.A() for large data sets, see #14 (version 0.1.5.9002)
• Automatically convert raw sfc samplers objects to sf objects in fm_int.list() (version 0.1.5.9003)
• Detect and warn about unsupported use of fm_segm objects in fm_int.list() (version 0.1.5.9004)
• Add fm_basis() and fm_fem() support for fm_tensor function spaces (version 0.1.5.9005)
• Add fm_CRS() support for terra objects (version 0.1.5.9006)

fmesher 0.1.5

• Fix bug in fm_matern_sample() that prevented the use of a non-NULL loc argument. For earlier versions, the workaround is to make a separate call to fm_evaluate() after calling fm_matern_sample().
• Improve speed of fm_block_log_shift() by an order of magnitude for multi-block cases.
• Fix bug in plot.fm_mesh_2d for meshes with 2D coordinate storage (version 0.1.4.9002)

fmesher 0.1.4

• Work around std::get<variant>() lack of support for MacOS < 10.14.

fmesher 0.1.3

• Fix bug in fm_rcdt_2d_inla() that gave different defaults for the extend and refine arguments when equal to TRUE, that should be treated the same as list() (version 0.1.2.9001)
• Fix bug in fm_rcdt_2d_inla() to properly update n basis counter element when removing unused vertices. (version 0.1.2.9002)
• Fix bug giving a spurious warning about inconsistent is.bnd for empty fm_segm objects, and inconsistent grp vector lengths. (version 0.1.2.9003)
• Convert some of the old potentially unsafe C++ pointer methods to type safe C++17 features

fmesher 0.1.2

• Various documentation improvements, in particular for INLA compatibility
• Modify mesh refinement tests to directly check the refinement criteria instead of the specific mesh result, to account for differences in floating point behaviour on M1 processors.
• Modify tests of non-mesh-generation features to use precomputed meshes or meshes with stable properties
• Protect against invalid tv inputs
• Revert from \text{} to \textrm{}, as AMS extensions are only supported from R 4.2.2 (https://www.stats.bris.ac.uk/R/doc/manuals/r-devel/R-exts.pdf 2023-08-24, page 90), and CRAN oldrel for macOS is 4.2.0, not 4.2.3

fmesher 0.1.1

• Simplify LICENSE information in the R package DESCRIPTION
• Fix example for legacy plot_PolySet method
• Fix C++ unused-variable warning detected by clang-tidy version 16.0.6
• Add workaround for sf::st_buffer not supporting negative distance for s2 with longlat coordinates. Fixes #5

fmesher 0.1.0

• Full conversion of the fmesher interface from the standalone binary in R-INLA (https://www.r-inla.org) to an interface powered by Rcpp (https://cran.r-project.org/package=Rcpp)
• Tools for 2D and 1D function spaces, see fm_mesh_2d() and fm_mesh_1d()
• Tools for CRS handling see fm_crs() and fm_transform()
• Plotting support for base graphics, rgl, and ggplot2
• Added basic GMRF tools, see fm_matern_precision()

fmesher 0.0.9

• Basic fmesher library I/O interface
• Added a NEWS.md file to track changes to the package.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
