Convert geojson file to R

Thank you. I will report this bug (I did not have the confidence to call
this a bug before).

Even using your code, I get the same output.

structure(list(X = c(-67.3804401, -67.36091, -67.3805899999999,
-67.3397099999998, -67.3780199, -67.3221199999999), Y = c(-55.5655699999996,
-55.5840098999999, -55.6004100000001, -55.6149699999997, -55.63521,
-55.6400899999997), L1 = c(1, 1, 1, 1, 1, 1), L2 = c(1, 1, 1,
1, 1, 1), L3 = c(1, 1, 1, 1, 1, 1)), row.names = c(NA, 6L), class =
"data.frame")

Thank you again.

This seems to be a weird bug in `st_read`. If you read it with an SQL
query that matches every row it works:

js = st_read("./countrymasks.geojson", query="select * from countrymasks

where 1 = 1")
Reading query `select * from countrymasks where 1 = 1' from data
source `/home/rowlings/Downloads/countrymasks.geojson' using driver
`GeoJSON'
Simple feature collection with 214 features and 15 fields
Geometry type: MULTIPOLYGON
Dimension:     XY
Bounding box:  xmin: -180 ymin: -55.79439 xmax: 180 ymax: 83.62742
Geodetic CRS:  WGS 84

But leave out the query and you get that C code level error. Another
equivalent query would be "select * from countrymasks" (without the
"where" clause) but this
triggers the error too. Very odd. Worth reporting as a bug?

Thank you for reply. When I try using sf, I get the following error;

Error in CPL_read_ogr(dsn, layer, query, as.character(options), quiet,  :
   attempt to set index 210/210 in SET_STRING_ELT.

Thanks again!

You're going to want to read the file with sf.

Try object <- sf::st_read("~countrymasks.geojson")

Greetings everyone,

I would like to convert the geojson file (

https://drive.google.com/file/d/18h3sOjZg5jp5euLTWRi5mC40Sja8TZDN/view?usp=sharing

)
to a dataframe - essentially obtain which has coordinates matched to a
country.

I have tried the following;

###
states <- geojsonsf::geojson_sf("~/countrymasks.geojson")
geo <- geojsonsf::sf_geojson(states)
sf <- sf::st_read(geo, quiet = T )
df <- as.data.frame(sf::st_coordinates(sf) )
##

But I get the following output, I am a bit lost. Any help will be

highly

appreciated.

Best,
