subscript

问题 I have a datatable in a shiny app, in which I want to add superscript to my observations. These should detail whether the observation is an estimate, and how far the year of the observation is from the reference year (this data is already in my dataset). For example a particular observation might display : "75(superscript)-3 e". Is this possible? 回答1: I had the same question today and this post helped me get some of the way there. There is a working example of this on How to add subscripts in

问题 I want to Draw a string on my JFrame that has subscripts and a font, I was trying to use an AttributedString but i didn't seem to want to work for whatever reason. It will either display just the font or just the subscripts but not both at once. private class DrawFormulas extends JComponent { public void paint(Graphics g) { Graphics2D G2D = (Graphics2D)g; G2D.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); g.setFont(F); AttributedString Trig = new

问题 I've seen this solved in other questions - but I think that because this NSDictionary is accessed via subscript it's throwing some errors. func pickRandomRecipe(arrayOfRecipes: NSArray) -> Dictionary<String,Any> { let randomRecipeIndex = Int(arc4random_uniform(UInt32(arrayOfRecipes.count))) //Could not cast value of type '__NSDictionaryI' (0x7fbfc4ce0208) to 'Swift.Dictionary<Swift.String, protocol<>>' (0x7fbfc4e44358) let randomRecipe: Dictionary = arrayOfRecipes[randomRecipeIndex] as!

问题 Using Xcode 7.2 and Swift 2.1.1 I am retrieving data from a .plist file The file contains data for a series of quizzes. The data for the quiz to be retrieved consists of an array of 12 questions and a corresponding array of 12 multiple choice options (4 members each). var quizId = “” var questions:[String] = [] var answers:[[String]] = [] The quiz id is passed in a segue from the previous view controller. Then the data is retrieved in ViewDidLoad. let path = NSBundle.mainBundle()

问题 I want to add an R^2 value to my plot. I passed the label to geom_text() as follows; geom_text(aes(x,y,label=caption),parse=T, data.frame(x=-2,y=80,caption=("R^2=0.43")))) but it plots as =(R^2,0.43). Any ideas? 回答1: You want your caption to be "R^2==0.43". Look at the help page for plotmath . There it shows that == gives you equals. EDIT: To answer the comment after the question, you can use atop in the expression. "atop(R^2==0.43,p==0.763)" This works for two lines, but not more. 来源： https:

问题 I know that we can produce a single subscript in matplotlib like $r_i will give me an r with "i" as the subscript. But I want to generate a subscript with say 3 or 4 letters, like r_ijk should give me an r with "ijk" as the subscript. When I do the above, I only get the first ("i") to be the subscript, the rest ("j" & "k") are becoming normal scripts. 回答1: I just tried r_{ijk} and it did the trick! I was previously trying with () braces. 来源： https://stackoverflow.com/questions/22322682

问题 In the python docx quickstart guide (https://python-docx.readthedocs.io/en/latest/) you can see that it is possible to use the add_run-command and add bold text to a sentence. document = Document() document.add_heading('Document Title', 0) p = document.add_paragraph('A plain paragraph having some ') p.add_run('bold').bold = True I would to use the same add_run-command but instead add text that is superscripted or subscripted. Is this possible to achieve? Any help much appreciated! /V 回答1: The

问题 Given a data.frame A, how can I use subscripted rows and columns names? Eventually I want produce a table through kable() in rmarkdown (output: word document). A <- data.frame(round(replicate(3, runif(2)),2)) rownames(A) <- c("Hola123", "Hola234") A X1 X2 X3 Hola123 0.47 0.55 0.66 Hola234 0.89 0.45 0.20 How could I make all numbers from row and column names subscripted when creating a table through kable(A)? I have tried: rownames(A) <- c(expression(Hola["123"]), expression(Hola["234"]))

问题 I'm trying to create a "sparse" vector class in C++, like so: template<typename V, V Default> class SparseVector { ... } Internally, it will be represented by an std::map<int, V> (where V is the type of value stored). If an element is not present in the map, we will pretend that it is equal to the value Default from the template argument. However, I'm having trouble overloading the subscript operator, [] . I must overload the [] operator, because I'm passing objects from this class into a
