dataframe - Multiply a data frame column with a single row in another data frame, R -

-

One more value to multiply each element of a column with each value in the row of another data.frame What's the way ?

I want to multiply df2 [1,] with df1 [, 1] and df3 dimension 5 lines X 5 column 

  df1 & lt; - data.frame (v1 = c (10, 20, 30, 40, 50), v2 = c (5, 10, 15, 20, 25)). Df1 V1 V2 1 10 5 2 20 10 3 30 15 4 40 20 5 50 25 DF 2 & lt; - Data. Frame (Albany = 0.5, Birmingham = 1.0, Tuscany = 1.5, New York = 2, Atlanta = 2.5, Alabama = 3) & gt; Df2 Albany Birmingham Tuscany New York Atlanta Alabama 1 0.5 1 1.5 2 2.5 3   
 Each of the output should have a column for each row and five lines of this type:  
 < Code> Albany Birmingham Tuscany New York Atlanta Alabama 1 5 10 15 20 25 30 2 10 20 30 40 50 60 3 15 30 45 60 75 90 4 20 40 60 80 100 120 5 25 50 75 100 125 150   
 In my real data set, there are 9500 rows in DF1 and DF2 has 210 columns. Therefore, output data frame I want to subscribe the rows of Nero (9500) x nacl (210)   
 
 
 Returns the data.frame of frame. Thus, you need  unlist  to get the vector:  
  df1 [, 1]% *% t (list (Df2 [1,]) # Albany Birmingham Tuscany New York Atlanta Alabama # [1,] 5 10 15 20 25 30 # [2,] 10 20 30 40 50 60 # [3,] 15 30 45 60 75 90 # [ 4,] 20 40 60 80 100 120 # [5,] 25 50 75 100 125 150

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...
