r - How do I apply an index vector over a list of vectors? -

-

I apply a long index vector (50 + non-sequential integer) in a long list of vectors (50 + letters) A common example is below: 

  & Gt; My.list & lt; - List (C ("A", "B", "C"), C ("D", "E", "F")) My.index & lt; - 2: 3   
 desired output  
  [[1]] [1] "b" [[2]] [1] "F" # # Or [1] "b" [1] "f" ## or [1] "b" "f"   
 I know that I can get the same value for each element By using:  
  & gt; Lapply (my.list, function (x) x [2]) ## or & gt; Lapply (my.list, '[', 2]   
 I can pull the second and third values ​​from each element:  
 > Lapply ( My.list, '[', my.index] [[1]] [1] "b" "c" [[2]] [1] "e" "f" for ## or & gt; (my J.in (i seq_along (my.list)) print (my.list [[i]] [[j]] [1] "b" [1] "e" [1] "c" [1 ] "F"   
 I do not know how to pull just one value from each element.  
 I have not found a few days and some examples of this , But it looks quite straight forward. Do I have something clear?  
 Thank you, Scott  < Whenever a problem that is similar to  lapply  but contains multiple parallel lists / vectors, With  map  or  mapply  ( map   mapply  with  SIMPLIFY = FALSE  hardcoded) A cover.  
 Try it:  
  Map ("[", My.list, my.index] # [[1]] # [1] "B" ## [[2]] # [1] "F"   
 .. or:  
  mapply ("[", my.list, my .index] # [1] "B" "F"

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
