r - How to round all values in a matrix? -

I use the following method to store all my relationships in the matrix:

  
 Code> corrs & lt; - cor (use dataset = "pairwise.complete.obs")    But now I want to round the values in two digits after a comma. How can I do that? I just got a round function, but it does not know how to implement all the values.   
 
  Just as in your second question, the function ( rounds ) Use :)  
  corrs & lt; - Round (Core (Dataset, Usage = "pairwise.complete.obs"), 2)    For example:  
  & gt; Goal (Core (car), 2) Speed speed 1.00 0.81 d 0.81 1.00

Integrate flash games in android app? -



    3 is a flash game that I want to integrate into a menu / list in the Android app. So when the user selects the game from the list, the game starts with the help of the Android Flash Player.   Is it better or better with webwave?   Is there any good tutorial?   Thank you!
