How do I write a json array from R that has a sequence of lat and long? -

how write json array r has sequence of lat , long?

i write:

[[[1,2],[3,4],[5,6]]]

the best can is:

tojson(matrix(1:6, ncol = 2, byrow = t)) #"[ [ 1, 2 ],\n[ 3, 4 ],\n[ 5, 6 ] ]"

how can wrap thing in array (the json kind)? of import me can write files geojson format linestring.

i utilize fromjson target object :

ll <- fromjson('[[[1,2],[3,4],[5,6]]]')  str(ll) list of 1  $ :list of 3   ..$ : num [1:2] 1 2   ..$ : num [1:2] 3 4   ..$ : num [1:2] 5 6

so should create , list of unnamed list, each containing 2 elements:

xx <- list(setnames(split(1:6,rep(1:3,each=2)),null)) identical(tojson(xx),'[[[1,2],[3,4],[5,6]]]') [1] true

json r
