R – Specify height and width of ggplot graph in Rmarkdown knitr output

Wrap the qplot in print.

knitr will do that for you if the qplot is outside a loop, but (at least the version I have installed) doesn't detect this inside the loop (which is consistent with the behaviour of the R command line).

You can achieve this in two ways:-

First way:- Get the info using google api

-(void)findAddresstoCorrespondinglocation
{
    NSString *str = [NSString stringWithFormat:@"http://maps.googleapis.com/maps/api/geocode/json?latlng=%f,%f&sensor=false",myCoordInfo.latitude,myCoordInfo.longitude];
    NSURL *url = [NSURL URLWithString:[str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
    ASIHTTPRequest *request = [[[ASIHTTPRequest alloc] initWithURL:url] autorelease];
    [request setRequestMethod:@"GET"];
    [request setDelegate:self];
    [request setDidFinishSelector: @selector(mapAddressResponse:)];
    [request setDidFailSelector: @selector(mapAddressResponseFailed:)];
    [networkQueue addOperation: request];
    [networkQueue go];

}

in response you will get all information about the location coordinates you specified.

Second Approach:-

Implement reverse geocoding

a.)add mapkit framework

b.)Make instance of MKReverseGeocoder in .h file

MKReverseGeocoder *reverseGeocoder;

c.)in .m file

self.reverseGeocoder = [[MKReverseGeocoder alloc] initWithCoordinate:cordInfo];
    reverseGeocoder.delegate = self;
    [reverseGeocoder start];

Implement two delegate methods of MKReverseGeoCoder

- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFailWithError:(NSError *)error
{
    NSLog(@"MKReverseGeocoder has failed.");
}

- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark
{
    MKPlacemark * myPlacemark = placemark;
    NSString *city = myPlacemark.thoroughfare;
    NSString *subThrough=myPlacemark.subThoroughfare;
    NSString *locality=myPlacemark.locality;
    NSString *subLocality=myPlacemark.subLocality;
    NSString *adminisArea=myPlacemark.administrativeArea;
    NSString *subAdminArea=myPlacemark.subAdministrativeArea;
    NSString *postalCode=myPlacemark.postalCode;
    NSString *country=myPlacemark.country;
    NSString *countryCode=myPlacemark.countryCode;
    NSLog(@"city%@",city);
    NSLog(@"subThrough%@",subThrough);
    NSLog(@"locality%@",locality);
    NSLog(@"subLocality%@",subLocality);
    NSLog(@"adminisArea%@",adminisArea);
    NSLog(@"subAdminArea%@",subAdminArea);
    NSLog(@"postalCode%@",postalCode);
    NSLog(@"country%@",country);
    NSLog(@"countryCode%@",countryCode);

    }
