问题 I have to adjust a code which works perfectly with a different data.frame but with similar conditions. Here an example of my data.frame: df <- read.table(text = 'ID Day Count 33012 9526 4 35004 9526 4 37006 9526 4 37008 9526 4 21009 1913 3 24005 1913 3 25009 1913 3 22317 2286 2 37612 2286 2 25009 14329 1 48007 9527 0 88662 9528 0 1845 9528 0 8872 2287 0 49002 1914 0 1664 1915 0', header = TRUE) I need to add a new column ( new_col ) to my data.frame which contains values from 1 to 4. These

问题 After reading this post: using javascript to add form fields.. but below, not to the side? I've made the button work! But I don't know how to receive the output. This is what I entered. var counter = 0; function addNew() { // Get the main Div in which all the other divs will be added var mainContainer = document.getElementById('mainContainer'); // Create a new div for holding text and button input elements var newDiv = document.createElement('div'); // Create a new text input var newText =

问题 I would like to merge different SPSS files. The PAID indicates different persons. The files also contain the variable ID which indicates the moment of measurement. So ID=1 means that the data are results of measurement one (ID=2 ; measurement two etc.). However, not all data files contain the same moments of measurement. I have already read the following post, but that has not completely answered my question: SPSS - merging files with duplicate cases of ID variable and new cases/variables

问题 I have 10 or so images coming in from flickr. At the moment they just come in as images with no individual ID or Class names. So I have: <img src="images/01.jpg" width="300" height="273" /> <img src="images/01.jpg" width="300" height="273" /> <img src="images/01.jpg" width="300" height="273" /> <img src="images/01.jpg" width="300" height="273" /> ...and so on. What I want to do is have: <img id="image1" src="images/01.jpg" width="300" height="273" /> <img id="image2" src="images/01.jpg" width

问题 Say I have a Father class to be inherited by Children classes, later I want to add more stuff into the Father class without modifying the original Father class, please teach me how could I do it. Let me clarify my question. Any valuables and methods in Father will automatically accessible to all the Children classes, right? For example: public class Father { public int a; public int b; public int c() { return a+b; } } public class Child : Father { private int d=a*b+c(); } Now I want to add a

问题 I have 2 lists of dataframes in R (where the respective dataframes in each list are the same size). Is it possible to add the respective dataframnes in each list together in one line. e.g. say we had list1 <- list('a' = data.frame('x'=c(0,1),'y'=c(2,0)), 'b' = data.frame('x'=c(1,1),'y'=c(1,1))) list2 <- list('a' = data.frame('x'=c(1,2),'y'=c(1,1)), 'b' = data.frame('x'=c(0,1),'y'=c(0,1))) So list1 is: $a x y 0 2 1 0 $b x y 1 1 1 1 And list2 is: $a x y 1 1 2 1 $b x y 0 0 1 1 The final output

问题 I'm a beginner in C++ and I started learning how to use QT components through code at MVS IDE. I still don't know if that was the best option to begin, but since I'm a java programmer, I made the path I made with Java (Swing components). So, my problem is, how to comunicate two class of my code, since in one I made the window frame and in the other I made my menu bar? In java I would make something like: JFrame frame = new JFrame(); JMenu menu = new JMenu(); frame.add(menu); Anyway, This is

问题 Consider: operator.add(a, b) I'm having trouble understanding what this does. An operator is something like +-*/ , so what does operator.add(a, b) do and how would you use it in a program? 回答1: Operator functions let you pick operations dynamically . They do the same thing as the operator, so operator.add(a, b) does the exact same thing as a + b , but you can now use these operators in abstract. Take for example: import operator, random ops = [operator.add, operator.sub] print(random.choice

问题 i want to import an existing Android Project(a small App that should be added to another Android Project soon) into another Android Project in order to test.
