R: Set X and Y limits when using qmap (ggplot2) -

-

I am trying to create a map using qmap (part of ggmap). To illustrate through the question here is an example piece of code. It is a sort of stupid, but it is cleaner than using my own data. 

  install.packages ("ggmap") library (ggmap) qmap ("Capital Building, Washington DC", Zoom = 15)   
 So my mine The question is: In the vicinity of the Capital Building I want to zoom a good bit (zoom = 15) to get lots of detail of the road. But I want to include Washington Monument in my map too. To do this, I want to expand the western part of the map and make it rectangular.  
 Does anyone know how to do this? Any insight would be much appreciated. Thanks for your patience with the beginning   
 
 
 Like this?  
   
  Library (ggmap) of cap & lt stack.imgur.com/8bbod.png geocode ("Washington Memorial, Washington DC") loc & lt; -. Unlisted ((cap + wash) / 2) ggmap (get_map (location = loc, zoom = 15)) + coord_fixed (ylim = loc [2] + 005 * c (- 1, +1))   
 then pulls in a map based on the coords between the Capitol Building and the Washington Monument in the middle of this path, then it  by establishing trim ylim .  
  unlist (...)  The reason for this is that  geocode (...)  a data frame and  get_map (.. )  wants a numerical vector.  
  Edit  Reply to Op's comment.  
  One aspect ratio of coord_fixed (...)  1: 1, which means that 1 degree latitude is the same length as 1 degree latitude. To get the original aspect ratio back from the map, use  coord_map (...) .  
  ggmap (get_map (location = loc, zoom = 15)) + Coord_map (ylim = loc [2] + 005 * c (-1, + 1))

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
