问题 My shiny app looks as follows so far (extract): ui <- fluidPage( headerPanel("title"), sidebarLayout( sidebarPanel( h4("header"), tags$hr(), # Input: Bilanzpositionen Passiv ---- fileInput("file1", "Kollektive hochladen", multiple = TRUE, accept = c("text/csv", "text/comma-separated-values,text/plain", ".csv")), ) ) ) # # # # # server <- function(input, output) { output$contents <- renderTable({ req(input$file1) bipop <- read.csv(input$file1$datapath, sep = input$sep, quote = input$quote) if

问题 In my app I want to give the user the opportunity to choose the site to explore. What I do is showing a list of the existing sites (using a String array) and then get the SiteCodeType with the valueOf() method of the enum. This value works with some APIs, but what I need is actually the specific ID of the site, and I can't find out how to get it. I hoped to get it somewhere using the SiteCodeType I already have. I saw both GlobalID and SiteID but I don't understand how to work with them.

问题 I have a question about global variables in python. If I got this correctly, all variables that I define in my class can be read from each method in this class. Now I thought that I could only write into the global variables if I mark them with global 'variableName' before. But here is what freaks me out: def foo(a): for i in range(a[0].__len__()): a[0][i] -= a[1][i] a = [[0,1,2,3,4,5,6],[0,1,2,3,4,5,6]] foo(a) print(a) gives me [[0, 0, 0, 0, 0, 0, 0], [0, 1, 2, 3, 4, 5, 6]] But WHY? I mean,

问题 I understand that in CUDA's memory hierachy, we have things like shared memory, texture memory, constant memory, registers and of course the global memory which we allocate using cudaMalloc(). I've been searching through whatever documentations I can find but I have yet to come across any that explicitly explains what is the global memory. I believe that the global memory allocated is on the GDDR of graphics card itself and not the RAM that is shared with the CPU since one of the

问题 I have a Swift noobie question on class method calls. I'm building a simple learning app for my kids using Sprite Kit. I have a global variable scoreCount defined in GameScene, where I pretty much do all my game logic such as detect correct answer and increment scoreCount. I also have GameOverScene. On both I show the Score -label. I'm keeping count of scores with the scoreCount-parameter (in GameScene). However as I'm quite new to Swift and Sprite Kit, I'm wondering how should I update the

问题 I want to make a new Application which I can control via keys from outside GUI. If the key was pressed there should be a text field changing at first. At last I want to make a timer start on keyPress. I googled and visit Stack Overflow but found nothing that could help me really to solve my problem. I found a post on Stack Overflow and tried the code. But I just get the key in a console and don't know how to request it on a GUI which is out of focus. Any help would be highly appreciable. 回答1:

问题 When answering Remove EOL spaces of selection only if there are, I noticed that my answer is not really satisfying: the pattern \ \+$ has to be typed twice: once for searching with :g once for replacing with :s First thought was to simply use g/\(\ \+$\)/s/\1//g but this gives me an error about an invalid back reference (E65). Is there a way to re-use the pattern used in :g for the [cmd] being executed? 回答1: You don't need \1 : :g/ \+$/s///g :g/pat/s//PAT/g is same as: :%s/pat/PAT/g 来源： https

问题 I have been trying to find the best solution to share some data beetween two componentes that share the same parent. I am using an angular-material stepper. Step 1 has one component and step 2 has another one. What i am trying to do is to "click" 1 button in the component from the step 1 and refresh an array of data that affects component in step 2. This is my code: Global service: export class GlobalDataService { private reserveSource = new BehaviorSubject<any[]>([]); currentReserve = this

问题 I have an Objective-C category of UIColor that I would like to "import" everywhere in my project. But instead of using the #import to every class that needs it I was told there was a way to set it up so all classes can see it. Anyone know how this is accomplished? Thanks in advance, Rob 回答1: Add that import to the precompiled header file (*.pch) in your project - that way it will be imported to any implementation file automatically. 来源： https://stackoverflow.com/questions/6707590/is-there-a

问题 I'm trying to be good, I really am, but I can't see how to do it :) Any advice on how to not use a global here would be greatly appreciated. Let's call the global G. Function A Builds G by AJAX Function B Uses G Function C Calls B Called by numerous event handlers attached to DOM elements (type 1) Function D Calls B Called by numerous event handlers attached to DOM elements (type 2) I can't see how I can get around using a global here. The DOM elements (types 1 & 2) are created in other
