To access address componet I used the following code

dat <- lapply(readLines("D:/Deepesh/All files/example1.json"), fromJSON)
res = lapply(dat, function(x) {

  lapply(x[["results"]], function(y) {

    do.call(rbind, lapply(y[['address_components']], function(z) {

      if (is.null(z)) {

        c(rep(NA, 3))}

      else {

        c(z[['types']][[1]], z[['long_name']], z[['short_name']])
      }
    }))
  })
})

this gives me following output

Everything is working fine except that I'm expecting "sublocalities" as output values rather than "political" in O/P fron the line "{"long_name":"Uday Baug","short_name":"Uday Baug","types":["political","sublocality","sublocality_level_2"]},"

It is not able to take "sublocality" from ["political","sublocality","sublocality_level_2"]} instead it is taking first element i.e "political" Any suggestion on what changes should be made in order to acheive the expected output. Any help would be much appreciated.

Thanks
