问题 I want my React function to re-render after I splice an array. Here Is (part of) the function (using Hooks): function showProblem() { const [andArray, setAndArray] = useState([]); const deleteTag = (i, arr) => { let and = andArray; switch (arr) { case "and": and.splice(i, 1); setAndArray(and); break; default: return null; } }; return( <div> {andArray.map((and, i) => { return ( <span onClick={() => deleteTag(i, "and")} key={i} > {and} </span> ); })} </div> ) } When I click on the SPAN element,

问题 I'm trying to create automated PDF RMarkdown reports for fitness testing data based on the training hub city. I believe I'm very close by following the outline here: R Knitr PDF: Is there a posssibility to automatically save PDF reports (generated from .Rmd) through a loop? However, this is creating reports with the same data for only 1 hub despite both being named differently (report.MTL.pdf and report.TOR.pdf). How can I get the subgroup to loop properly to show data from the different hubs

问题 I'm trying to figure out how to draw graphics in XNA, and someone else suggested this. But before I attempt to use this... If I create and use this camera, and set LEFT,TOP to 0 and WIDTH=256 and HEIGHT=240, anything I render to the screen will use these coordinates? So a box with a width and height of 1, if set to 0,0 will take up space from 0,0 to 1,1? 回答1: The function you are referring to is: Matrix.CreateOrthographicOffCenter(left, right, bottom, top, zNearPlane, zFarPlane) . This

问题 I'm currently following a series on Java game development from scratch. I understand most java and oop concepts but have very little experience when dealing with graphics and hardware acceleration. The lines of code that I am questioning are: private BufferedImage image = new BufferedImage(WIDTH, HEIGHT, BufferedImage.TYPE_INT_RGB); private int[] pixels = ((DataBufferInt) image.getRaster().getDataBuffer()).getData(); The BufferedImage "image" variable is always the variable being drawn to the

问题 I have had an issue by using the same reactive expression in renderPlot() and in downloadHandler() . I want to use the same reactive expression to minimize maintenance later. I have created two examples which create very simple figures (mwe1 creates a jpeg which you can download, mwe2 does not). I prefer a solution which uses a creative expression which can be both used by renderPlot() and downloadHander() as in mwe2. Is anybody able to help me with this? Thanks in advance! mwe1 <- function()
