function

问题 I have 3 columns. First column has unique ID, second and third columns have string data and some NA data. I need to extract info from column 2 and put it in separate columns and do the same thing for column 3. I am building a function as follows, using for loops. I need to split the columns after the third letter. [For example in the V1 column below, I need to break AAAbbb as AAA and bbb and put them in separate columns. I know I can use substr to do this. I am new to R, please help. UID * V1

问题 Im trying to query an azure table from a function ( using Get-AzTableRow ) . Works very well from my laptop but the module "aztable' is not present in the azure function, and therefore all i get is a red screen :( Is there a way to install it ? Thanks ! David 回答1: You do not need to install the AzTable module in the Azure Function yourself. When you run the command, it will install the corresponding module for you. Here are the screenshots: The example of the AzTable module: $location =

问题 When I import and use a function in a python(2.6.5) program, I get an error: from Localization import MSGR title = Localization.MSGR("Logfile from Ctf2Rrl.") NameError: global name 'Localization' is not defined Could you please explain why? Regards, 回答1: If you import your method like this, you can user MSGR but not Localization.MSGR :) If you want to use Localization.MSGR , you can just import Localization 回答2: The import statement of the form: from foo import bar Doesn't introduce the

问题 I have a div, when I clicked on it, should turn all the elements in the .counter class to red, but at the moment it does nothing. I believe you have to run through a loop first and then use this somehow to select all elements in the class width JS? CSS .counter { width: 100px; height:100px; background-color:orange; } #btn { background-color:aqua; width:50px; height:50px; position:absolute; left:200px; top:10px; } HTML <div class="counter"></div> <br> <div class="counter"></div> <br> <div

问题 I have made a checkout form that displays the cost of a product, the subtotal, GST cost, delivery cost, and total price. What id like to do is take the cost of each product which has the class class = "price" (but id assume that they may need an id), and add them together to get the total. This total would be calculated with an increase of 15% from the value of the subtotal plus the cost of delivery. Here is the checkout form (sorry for the length) ~ there is some styling that isn't relevant

问题 So, this is my first assignment fiddling with functions in C++ - which I thought I understood being as they're rather similar to methods with C#. But, although my main calls my function fine, and the function runs and returns to the main - It doesn't send back the variable information that it called when it returns. I'm not exactly sure what I've done wrong - it appears to be set up appropriately (IE - Like the sample code in my book for a return) Here's the main code... #include <iostream>

问题 I' m building a page loader with canvas, and using the es6 classes... ALthough at the moment I can't make it work properly.. one of the reason is that I can't find a way to clear the canvas in progression. This is my code so far : class Loader { constructor (width, height) { this.width = width this.height = height } _init() { this._createCanvas() this._bindEvents() } // create canvas _createCanvas () { this.canvas = document.createElement("canvas") document.body.appendChild(this.canvas) this

问题 I'm a newbie in Unity Using Unity Inspector i have setup a button that makes a callback to a function (OnClick), it works fine but only once, to fire the action again i need to release and click the button again How can i make that the function keeps running over and over as long as the button is pressed? (like a machine gun) public void MoveLeft ( ) { transform.RotateAround(Camera.main.transform.position, Vector3.up, -rotation / 4 * Time.deltaTime); infopanel.RotateAround(Camera.main
