Using visNetwork to dynamically update nodes in R

由 我的未来我决定 提交于 2019-12-02 20:03:03
问题 the below snapshot visual is created using the "visNetwork" package. My requirement here is that I have to hard code the edges and also after using visHierarchicalLayout(), I am not able to see them in order, Please help me with a dynamic approach such that no matter how many numbers, I get consecutive numbers in order without hard code. Thanks and please help. library(visNetwork) nodes <- data.frame(id = 1:7, label = 1:7) edges <- data.frame(from = c(1,2,3,4,5,6), to = c(2,3,4,5,6,7))

How to create a get Method with nodes off a generic type in java

由 孤者浪人 提交于 2019-12-02 19:27:35
问题 I am implementing a cyclic DoublyLinkedList data structure. Like a singly linked list, nodes in a doubly linked list have a reference to the next node, but unlike a singly linked list, nodes in a doubly linked list also have a reference to the previous node. Additionally, because the list is "cyclic", the "next" reference in the last node in the list points to the first node in the list, and the "prev" reference in the first node in the list points to the last node in the list. I need help

How to implement an assignment operator in linked list class

由 假如想象 提交于 2019-12-02 18:52:15
问题 I am having difficulty figuring out how to implement the rule of 5 in my doubly linked list class. I get the concept of them, it's just lost with how to code it. I have attempted the destructor and copy operator, but at a stand still going forward with the rest. Any help/guidance is appreciated, thanks. destructor/copy: ~DList() { Node* current = front_; while (current != back_) { front_ = front_->next_; delete current; current = front_; } } // copy ctor DList(const DList& rhs) { const Node*

What is a node in Javascript?

由 故事扮演 提交于 2019-12-02 16:49:19
I was wondering what exactly a node is in JavaScript? As in the functions: element.nodeType row.parentNode.removeChild(row); A "node", in this context, is simply an HTML element. The "DOM" is a tree structure that represents the HTML of the website, and every HTML element is a "node". See Document Object Model (DOM) . More specifically, "Node" is an interface that is implemented by multiple other objects, including "document" and "element". All objects implementing the "Node" interface can be treated similarly. The term "node" therefore (in the DOM context) means any object that implements the

Selectively copy and update xml nodes using XSLT

由 ♀尐吖头ヾ 提交于 2019-12-02 13:17:57
I'm working with an xml that I need to copy and update to pass on for further processing. The issue I'm having is that I have not figured out an efficient method to do this. Essentially, I want to update some data, conditionally, then copy all the nodes that were not updated. Why this is challenging is due to the volume and variance in the number and name of nodes to be copied. I also want to NOT copy nodes that have no text value. Here is an example: INPUT XML <root> <PersonProfile xmlns:'namespace'> <ID>0001</ID> <Name> <FirstName>Jonathan</FirstName> <PreferredName>John</PreferredName>

python check string contains all characters

由 谁说我不能喝 提交于 2019-12-02 13:12:54
I'm reading in a long list of words, and I made a node for every word in the list. Each node has an attribute 'word' for their position in the list. I am trying to connect a node to the next node if the next node is the previous node, with an addition of just one letter I also alphabetically ordered each word per character, so that CAT -> ACT I want to draw an edge from each unique starting word, to all of the possible chains, so I can see all the possible chains in the list. For example A -> AN -> TAN -> RANT However A --x-> T This is my attempt for i in range(0, G.number_of_nodes()-1): if (

D3.js: Dynamically generate source and target based on identical json values

由 雨燕双飞 提交于 2019-12-02 12:13:12
问题 Good day, I am a novice in d3/javascript and this may be an easy/repeated question, but I just cannot get this section of my code to work.. I have this json array here: var myArray = [{"id": "red", "value":"1"}, {"id": "orange", "value":"2"}, {"id": "yellow", "value":"3"}, {"id": "green", "value":"1"}, {"id": "blue", "value":"1"}, {"id": "violet", "value":"3"}]; I understand that for me to create links between nodes in D3, I need an array with a [{"source": "___", "target": "___"} structure.

Magento XML build-up in plain english?

由 淺唱寂寞╮ 提交于 2019-12-02 10:27:24
I've been reading about Magento and I understand the core flow of its request cycle etc.. (configuration based MVC and class overriding and such..) However, I cannot seem to find a good article/documentation on the specifics of things - especially when it comes to different nodes required to build the config.xml for custom module etc..OR anything on XML build-up. If anybody could direct me to the "real good stuff"..article, documentation, tutorial..anything please. Thanks 来源： https://stackoverflow.com/questions/13461221/magento-xml-build-up-in-plain-english

Refill Stack using Node Implementation

由 梦想与她 提交于 2019-12-02 10:21:11
I'm having a hard time refilling the stack after i take it all off in order to print it out. I am using node implementation so i think this fact is what is confusing me. Any suggestions would be appreciated, thank you. This is my original stack::print() // Function to print Gumball info field (color and counter) void Stack::print() { Node *p; Type x; while(top != NULL) { p = top; x = p -> getinfo(); cout << " " << x.color << " " << " " << x.counter << endl << endl; top = p -> getnext(); } return; } This is my stack with my attempt to loop and store in temp. It compiles but still is not working

My program replaces all the string data types in all the nodes in the linked list
