由 霸气de小男生 提交于 2019-11-30 17:04:20
Is there a way to use a node as a link to an external website using the function forceNetwork() in the networkD3 package in r ? I was thinking maybe modifying the clickAction ? Example data: library(networkD3) data(MisLinks) data(MisNodes) # Create a random URL in the nodes dataset MisNodes$URL <- paste0("http://www.RANDOMLINK_", sample(1:100, NROW(MisNodes)), ".com") head(MisNodes) MyClickScript <- 'alert(d.index)' forceNetwork(Links = MisLinks, Nodes = MisNodes, Source = "source", Target = "target", Value = "value", NodeID = "name", Group = "group", opacity = 0.8, clickAction = MyClickScript

Attempting to make a fairly generic Sankey diagram with the help of R's networkD3 package. Just for reference--here's the example from the package's manual library(networkD3) library(jsonlite) library(magrittr) energy <- "https://cdn.rawgit.com/christophergandrud/networkD3/master/JSONdata/energy.json" %>% fromJSON sankeyNetwork(Links = energy$links, Nodes = energy$nodes, Source = "source", Target = "target", Value = "value", NodeID = "name", units = "TWh", fontSize = 12, nodeWidth = 30) which results in: My fairly straightforward extension consists of building a diagram with the following

问题 I'd like to make some style changes to my leaflet map. Is it possible to include style elements OR a custom path to a css file either via htmlwidgets for R or LeafletR? Best 回答1: With no code whatsoever in your question, answering is very difficult. I'll attempt an answer. There are two methods of adding custom CSS to an htmlwidget . I will caution up front though that you will need to be very specific or use the !important override, since there is already quite a bit of CSS that is

How to arrange HTML Widgets inside of a RMarkdown Document (PDF, HTML)

由 只愿长相守 提交于 2019-11-30 04:58:27
问题 I'm working in a R notebook and would like use it to create two ouptuts: an HTML document and PDF document. My analysis includes leaflet maps (html widgets), which is causing problems when I knit the notebook to a PDF document . Thanks to the webshot function now included in the knitr package, "knitr will try to generate static screenshots for HTML widgets automatically using the webshot package" (https://github.com/yihui/knitr/blob/master/NEWS.md). This works fine when my output is a series

R Shiny includeHTML missing htmlWidgets in a reactive context

UPDATE: I posted a related question here I need to include an html file in shiny using includeHTML. The file is generated by rmarkdown, and has a large number of htmlWidgets. Shiny is showing the html file, but the htmlWidgests are missing. The problem occurs only when includeHTML is in server.R, but works ok if includeHTLM is in ui.R. I need to update file.html so includeHTML must be used in a reactive context. The file.rmd is somthing like this --- title: "test" author: "me" date: '`r Sys.Date()`' output: html_document --- ```{r} df<- data.frame(a = c(1:10), b = c(1:10)) rpivotTable:
