htmlwidgets

问题 I am drawing pie charts for each node as shown in the image below. For the base map (i.e nodes and their connected edge), I am using SVG image and overlaying the pie on the top of the SVG image. Previously, I was putting the code for SVG Image in HTML and was putting the pie charts on top of that using js and d3. Now, I need to create the HTMLWidgets so that I can use it anywhere. Here, I am not able to figure out that how can I use my svg image within HTMLWidget so that I can make the exact

问题 when I am ploting a directed graph with NetworkD3 , The edges are not directed , how can I fix it ? an Example : library(networkD3) data(MisLinks) data(MisNodes) forceNetwork(Links = MisLinks, Nodes = MisNodes, Source = "source", Target = "target", Value = "value", NodeID = "name", Group = "group", opacity = 0.8) I want the result to be directed This is the definetion of directed Graph: "A directed graph is graph, i.e., a set of objects (called vertices or nodes) that are connected together,

问题 I'm trying to display the value variables of nodes and links in a networkD3 forceNetwork diagram as tooltips. To do this, I am using Shiny with htmlwidgets and the external JS library Tippy. Here is what I have so far: library(shiny) library(htmlwidgets) library(networkD3) fn <- forceNetwork( Links = MisLinks, Nodes = MisNodes, Source = "source", Target = "target", Value = "value", NodeID = "name", Group = "group", opacity = input$opacity) tippyJS <- 'tippy(".node")' server <- function(input,

问题 I would like to add a feature (a popover, or some other function?) to the central graphviz nodes in my shiny app that, when selected by mouse click, they display information (e.g. the info column in the centre_nodes file). Given that there's a tooltip property to these nodes, I think/hope the computer must 'see' them but I haven't figured out a way to connect the two and establish this behaviour... I've explored a variety of methods (e.g. reactR, html tags, hover.css, shinyBS, d3, pipeR, XML,

问题 I'm working on a shiny flexdashboard, and one of the elements is a datatable with a lot of columns. Currently the columns are so many that they exceed the width of the app. Instead of adding a scroll bar I would prefer to simply reduce the font used in datatable so that each column will be smaller. Is this possible? 回答1: Found the answer. Needed to wrap renderDataTable in a div. div(renderDataTable(table()),style = "font-size:80%) 来源： https://stackoverflow.com/questions/46534677/reduce-font

问题 I use saveWidget function in htmlwidgets to save HTML widgets in R. I got the saved HTML files with width 960 and height 500. I am pretty sure that I can resize the widget within knitrOptions parameters but I can not find out the list of the parameters to resize the widget. I have tried: library(htmlwidgets) saveWidget(htmlplot, file, knitrOptions = list(width = 1200, height = 700) I also have tried using fig.width , defaultWidth , etc. but none of them are worked. How could I resize the
