version 1.0-17

  • st_filter.sf() correctly scopes x and y arguments using !! operator

  • [.sfc and [<-.sfc use matrix/array type subsetting for sfc objects that have a dim attribute

  • add st_exterior_ring() to extract exterior rings (remove holes); #2406

  • add text.sf(), text.sfc(), points.sf(), points.sfc() to annotate base plots at geometry centroids; #2399

  • st_sf() no longer strips tbl or tbl_df class labels; #2378

  • st_layers() returns an object of class c("sf_layers", "data.frame"), with a dedicated print method.

  • when dim is not XYZM, interprets a length 4 coords argument to specify the corners of a rectangular polygon; #2357

  • st_interpolate_aw() gains an na.rm argument, for removing features with NA attributes before interpolating; #830

version 1.0-16

CRAN release: 2024-03-24

  • st_join() no longer renames the geometry column; #2327

  • st_sample() works when unprojected polygon geometry crosses the antemeridian; #2331

  • clean up and modernization of S3 registration of methods and tests; #2285, #2288, #2316, #2341, #2342, by @olivroy

  • [.sfc works when setting argument op; #2320

  • st_sample() for polygons is sensitive to setting oriented = TRUE to prevent wrongly correcting ring directions; #2308

  • add support for the GDAL footprint utility (requiring GDAL >= 3.8.0) to gdal_utils; #2305, by @goergen95

  • existing environment variables PROJ_LIB and PROJ_DATA are (again) ignored on sf binary CRAN installations (win + macos), effectively by overwriting them during the R session and restoring them on exit; this does not happen if environment variable R_SF_USE_PROJ_DATA is set to true. #2298

  • add st_line_project() to find how far a point is when projected on a line; #2291

  • add st_line_interpolate() to obtain a point at a certain distance along a line; #2291

version 1.0-15

CRAN release: 2023-12-18

  • st_transform() responds to in-session changes to sf_proj_network(); #2166

  • plot.sf(): key.width is sensitive to pointsize graphics parameter par("ps"); keys with factor levels suggest a proper size if they won’t fit.

  • plot.sf(): key.pos can hold a second value in [0, 1] determining the relative position of the key in the available space

  • [<-.sf fixes the agr attribute when it is broken; #2211

  • if the env. variable ADD_SF_NAMESPACE is set to true, sf objects get a new attribute, .sf_namespace, which forces loading the sf namespace when it has not been loaded so far, e.g. for proper printing or plotting of an sf object; #2212 by Mike Mahoney

  • distinct.sf() is type-safe for sf objects with zero rows; #2204

  • summarise.sf() raises an error if .by is given but no across() on the geometry; #2207

  • st_write() matches fields on name first, than on position; this matters for formats that have pre-defined names, such as GPX; #2202

  • st_crs(x)$ud_unit returns the unit of the coordinate reference system of x

  • geometric predicates return sgbp objects omitting self-intersections etc. by passing remove_self = TRUE and unique symmetric relationship by passing retain_unique = TRUE (to ... if needed); this simplifies identifying (and removing) duplicated geometries; duplicates are identified by e.g. by st_equals(x, retain_unique = TRUE) |> unlist() |> unique(); #1893

  • when st_crs() is called with a WKT2 as text input, its input field will be replaced with the CRS name (if it has one).

  • GEOS (>= 3.9.0) operations use GEOSGeom_setPrecision_r to set precision of geometries; #1535

  • add s2 to Imports:

  • add Dewey Dunnington to contributors

  • Only when package s2 >= 1.0.1 is available: support for spherical geometry operators (predicates, transformers, measures, nearest point/feature) for geographic coordinates in package s2 is now by default switched off, and can be switched on by sf_use_s2(TRUE); see and vignette sf7. It is planned to be switched on by default in sf 1.0-0.

  • drop Z and/or M coordinate in st_as_s2(), with message

  • geometry predicates and transformers gain an … argument to pass s2::s2_options()

CRAN release: 2020-04-06

version 0.9-0

CRAN release: 2020-03-24

  • see r-spatial blog post:

  • modify crs objects to reflect our post-proj4string world (#1146; #1225): crs objects contain two fields, input with the user input (if any), and wkt with a well-known-text (or WKT2) representation of the coordinate reference system. crs objects have a $ method to dynamically retrieve the epsg (integer) or proj4string representation, using e.g. x$epsg.

  • support for PostGIS 3 using WKT and the new-style crs objects; #1234, #1303, #1308 by @etiennebr

  • st_write_db() and st_read_db() are defunct. Use st_write and st_read instead.

  • add st_reverse() methods to reverse points in a linestring (requires GEOS >= 3.7.0); #1246

  • no longer requires maptools and sp; drop dependency on maptools.

  • conversion between spatstat classes owin, ppp and psp and sf classes no longer use maptools; #1204

  • gdal_utils() processes open options -oo and -doo properly;

  • new method st_shift_longitude() to re-center data for a Pacific view. #1218

  • output of st_as_text() with MULTIPOINT has nested parentheses around points. E.g., MULTIPOINT ((0 0), (1 1)) instead of MULTIPOINT (0 0, 1 1); #1219, #1221

  • NULL geometries read by GDAL are returned as empty geometries; #1119

  • restore compatibility with GDAL 2.0.x versions (which won’t have gdal_utils); #686

  • read_sf() can also read tables without geometry; #684, by Andy Teucher

  • method distinct() works; #669, #672

  • +, -, * and / for pairs of geometries (sfg, sfc) return geometric union, difference, intersection and symmetric difference, respectively.

  • st_cast() from MULTIPOLYGON to MULTILINESTRING should work properly; #660

  • all Rcpp interfaces needed by package stars have been moved into sf; pkg stars is R-only, and only sf needs linking to GDAL.

  • gdal_utils() interfaces the 9 gdal utils using the C++ API

  • improve resetting (base) plots; add reset = FALSE in a call to plot to enable adding to plots that have a legend

  • st_read() returns a data.frame when a table contains no geometries, rather than giving an error; it does emit a warning in this case. See

  • add pillar to Imports: to provide method for printing WKT geometries in tibbles

  • st_cast from MULTIPOLYGON to MULTILINESTRING no longer changes the number of features/feature geometries, but conversion from MULTIPOLYGON to LINESTRING (typically) does; #596

  • functions depending on liblwgeom (st_make_valid, st_geohash, st_plit) have been moved to their own package,; argument use_gdal of st_transform has been deprecated, instead one can use lwgeom::st_transform_proj; sf no longer tries to link to liblwgeom; #509, #537, #487

  • st_read, st_sf and st_sfc gain a parameter check_ring_dir (default: FALSE) that checks ring directions and corrects to: exterior counter clockwise, holes clockwise, when seen from above.

  • get rid of classInt::classIntervals warning if number of unique values is smaller than the number of breaks asked for

version 0.5-5

CRAN release: 2017-05-05

  • summarise.sf always returns an sf object, also for global (non-grouped) summaries.

  • summarise.sf gains an argument do_union which determines whether to union the geometries for which a summary is given, or to st_combine them (not resolving boundaries); #331

version 0.4-1

CRAN release: 2017-03-28

  • restore 3.3.0 and c++11 requirement

  • st_read respects time that is read as UTC

  • st_write writes time always as UTC, since GDAL does not have a mechanism to define local timezones other than “unknown” or “local”

  • st_length works for POINT and MULTIPOINT (returning 0); POLYGON and MULTIPOLYGON are converted to MULTILINESTRING before computing length, thus giving polygon perimeter (#268)

  • st_write has update depend on driver; for databases, the default is TRUE, otherwise FALSE (it refers to update of the database, and not to overwriting the table in the database, this will by default not succeed); #274

  • st_read supports reading objects with multiple geometry columns #257 #255

  • support ggplot’ing geometrycollections

  • drop C++11 requirement, allowing build for older R versions

  • add st_proj_info, modelled after rgdal::projInfo

  • overwriting datasets with st_write() is no longer allowed; update=TRUE appends to them, permitted the driver supports appending.

  • st_write gains an argument, update, which when TRUE will try to append to existing datasets (#204)

  • added list of corresponding function for migration from sp, rgdal and rgeos to sf at
