Hi,
I'm trying to do reversegeocoding on a large dataset. I'm using "RJSONIO"
library and using Google map API to get the location of the given lat-lon
in the dataset. After 100 or 150 successful displaying location information
it is showing
Warning message - "In readLines(con) : cannot open: HTTP status was '0
(null)'"
and Error : "Error in fromJSON(paste(readLines(con), collapse = "")) :
error in evaluating the argument 'content' in selecting a method for
function 'fromJSON': Error in readLines(con) : cannot open the connection"
Please help me to solve the issue.
location function is as follows :
location<-function(latlng){
latlngStr <- gsub(' ','%20', paste(latlng, collapse=","))
library("RJSONIO") #Load Library
#Open Connection
connectStr <- paste('
http://maps.google.com/maps/api/geocode/json?sensor=false&latlng=',latlngStr,
sep="")
con <- url(connectStr)
data.json <- fromJSON(paste(readLines(con), collapse=""))
close(con)
data.json <- unlist(data.json)
if(data.json["status"]=="OK")
address <- data.json["results.formatted_address"]
print (address)
}
I'm using R version 3.2.1 and Ubuntu 14.10 OS.
Thank you.
