Removed an unused V8 call to geojsonhint
Removed all remaining references to rgeos
This is a tiny patch release with no user-facing changes.
Added \alias{geojsonio-package} to man/geojsonio.rd.
topojson_write() has been restored, and now supports conversion to topoJSON
formats. User reports indicate output files might be larger than anticipated;
PRs to address this are welcomed. Huge thanks to @Shaunson26 for this PR!sprintf() usage within the projections() function; only run sprintf on a particular string if it has length > 0 (#172)as.json() when the input is the output of topojson_list() - we weren't constructing the TopoJSON arcs correctly (#160)geojson_read(): now using package geojsonsf to read geojson (#163)stringsAsFactors behavior in R v4 (#166) (#167)topojson_write() defunct until we can sort out issues with new sf version (#168)geojson_sf() and geojson_sp() now accept strings in addition to json, geoson_list and geojson_json types (#164)topojson_json() and topojson_list() gain params object_name and quantization to pass through to geojson_json() (#158)writeOGR replaced with st_write and readOGR with st_read; this should not create any user facing changes, but please let us know if you have problems with this version (#41) (#150) (#157)geojson_read() gains new S3 method geojson_read.PqConnection for connecting to a PostgreSQL database set up with PostGIS. See also ?postgis for notes on Postgis installation, and setting up some simple data in Postgis from this package (#61) (#155) thanks to @fxigeojson_read() instead of going through package sp now goes through package sf for a significant speed up, see https://github.com/ropensci/geojsonio/issues/136#issuecomment-546123078 (#136)geojson_list() gains parameter precision to adjust number of decimal places used. only applies to classes from packages sp and rgeos (#152) (related to #141) thanks to @ChrisJones687file_to_geojson() now using https protocol instead of http for the online ogre service called when using method = "web"geojson_read() to fail better when using method="web"; and update docs to note that method="web" can result if file size issues, but method="local" should not have such issues (#153)print.location method to not conflict with dplyr (#154)geo2topo() gains a new parameter quantization to quantize geometry prior to computing topology. because topojson_write() uses geo2topo() internally, topojson_write() also gains a quantization parameter that's passed to geo2topo() internally (#138) thanks @pvictorsf instead of sp in topojson_read(). note that the return object is now class sf instead of classes from the sp package (#144) (#145)type parameter in topojson_json() now set to type="auto" if the input is an sf/sfc/sfg class object (#139) (#146)geojson_list.sfc() for changes in sf >= v0.7, which names geometries, but that's not valid geojson (#142)lint() and validate()
are now defunct. They have been marked as deprecated since v0.2. See the package geojsonlint on CRAN for linting geojson functionality (#135) (#147)topojson_write() gains a new parameter object_name. With it you can set the name for the resulting TopoJSON object name created. As part of this geo2topo() also gains a new parameter, similarly called object_name, that does the same thing as for topojson_write(). (#129) (thanks @josiekre) PR (#131)geojson_sf() to convert output of geojson_list() or geojson_json() to sf package classes - as an analog to geojson_sp()geojson_json() gains option with the type parameter to skip a coercion to the geojson package class geoclass. Using type = "skip" you can skip the geoclass class coercion, which in some cases with large datasets should have performance improvements (#128) PR (#133)geojson_sp() with the newest version of rgdal. This was resolved by using the sf package instead to read GeoJSON. This had a knock-on benefit of speeding up reading GeoJSON. In addition, sf is now in Imports instead of Suggests (#130) PR (#132)geojson_atomize to "atomize" a FeatureCollection
into its features, or a GeometryCollection into its geometries (#120)
via (#119) thx @SymbolixAUtopojson_list and topojson_json for converting
many input types with spatial data to TopoJSON, both as lists and
as JSON (#117)geojson_json uses brief output provided by the geojson
package - this makes it less frustrating when you have an especially
large geojson string that prints to console - this instead prints a
brief summary of the GeoJSON object (#86) (#124)geojson_json to make type
parameter more flexible (#125)topojson_write - we were writing topojson file, but also
a geojson file - we now cleanup the geojson file (#127)topojson-server.js from within the
package instead of from the web. This makes it so that the
package doesn’t make any web requests on load, which prevented package
from loading when no internet connection available. (#118)geo2topo, topo2geo, topojson_write, and topojson_read for working with TopoJSON data - associated with this, we
now import geojson package (#24) (#100)geojson_write and geojson_json now pass ... argument through to
rgdal::writeOGR or jsonlite::toJSON depending on the class/method. For
those methods that use the latter, this now allows setting of the na
argument to control how NA values are represented in json, and the
pretty argument to control whether or the resulting json is
pretty-formated or compact (#109) (#111)geojson_json and geojson_write now convert unsupported classes to
their basic class before conversion and/or writing to geojson. This was most
commonly occurring with fields in sf objects calculated by sf::st_area
and sf::st_length which were of class units. (#107)GDAL version >= 2.2.0 where the layer name in
a geojson file was not detected properly (#108)convert_wgs84 to do minimal test of
output, and to conditionally test only if sf is available (#103)geojson_json, geojson_list, and geojson_write gain new S3 methods:
sf, sfc, and sfg - the three classes in the sf package (#95)geojson_json, geojson_list, and geojson_write gain two new
parameters each: convert_wgs84 (boolean) to convert to WGS84 or not (the
projection assumed for GeoJSON) and crs to assign a CRS if known
(#101) (#102)geojson_json() for non-sp classes now only keeps seven decimal places
in the coordinates. This follows the default that GDAL uses.methods/stats/utils
instead of importing themmethod parameter in geojson_read
clarifying what the options are for (#93) thanks @bhaskarvkto_json now defaults to 7 digits, which is used in
as.json and geojson_json (#96)geojson_read to read correctly from a URL - in addition
to file paths (#91) (#92) thanks @lecygeojson_read to read non-.geojson extensions (#93)
thanks @bhaskarvkgeojson_json() - moved to
reading in json with readr::read_file() (#85) thanks @javrucebo !file_to_geojson() to use httr::write_disk() instead of
download.file() (#83) thanks @patperulint() and validate()
are now deprecated, and will be defunct in the next version of this
package. See the new package geojsonlint on CRAN for linting
geojson functionality (#82)geojson_sp.json() added to geojson_sp() to handle json
class inputsencodin="UTF-8" to httr::content() callsgeojson_write() didn't overwrite existing files despite saying so.
New parameter added to the function overwrite to specify whether to
overwrite a function or not, which defaults to TRUE (#81)
thanks @Robinlovelace !geojson_sp() to convert output of geojson_list() or
geojson_json() to spatial classes (e.g., SpatialPointsDataFrame) (#71)rgdal > v1.1-1
given fix to make writing multipolygon objects to geojson correct (#69)lint() function, due to bug in passing data to the Javascript
layer (#73)as.json() (#76)map_leaf() uses the leaflet package to make maps, with
S3 methods for most spatial classes as well as most R classes, including
data.frame's, lists, vectors, file inputs, and more (#48)geojson_read() now optionally can give back a spatial class object,
just a convenience in case you want to not get back geojson, but a
spatial class (#60)leaflet R package is on CRAN, put back in examples using
it to make maps (#49)geometry="polygon" to
all geojson_*() functions that have .list methods. This checks to
make sure inputs have the same first and last coordinate pairs to
