htmlwidgets

I want to put HTML widgets like formattable (from formattable package) in an HTML page generated through RMarkdown. I need the widgets to be generated from within a for loop. How can i do that? With or without print() , both don't work. This is an example code (partly taken from formattable homepage ): --- title: "formattable example loop" output: html_document --- ```{r} library(formattable) df <- data.frame( id = 1:10, name = c("Bob", "Ashley", "James", "David", "Jenny", "Hans", "Leo", "John", "Emily", "Lee"), age = c(28, 27, 30, 28, 29, 29, 27, 27, 31, 30), grade = c("C", "A", "A", "C", "B"

Within the leaflet package for R, is there a way to click on a marker, and be directed to a URL?* This seems to be possible in JS . It's easy to add a standalone Popup with a URL: library(leaflet) content <- paste(sep = "<br/>", "<b><a href='http://www.samurainoodle.com'>Samurai Noodle</a></b>" ) leaflet() %>% addTiles() %>% addPopups(-122.327298, 47.597131, content, options = popupOptions(closeButton = FALSE) ) It's also straightforward to add a Marker that, when clicked, provides a URL in the popup: leaflet() %>% addTiles() %>% addMarkers(-122.327298, 47.597131, popup = content, options =

The MWE below oversimplifies my real goal. However, I have a background image that takes a long time to draw (in the example below it is simply a scatterplot of 32 mtcars dataset values). Users can click on certain points from my background image, and this will cause new points to be plotted. My aim is for these new points to simply be redrawn on the top layer, while the background image scatterplot does not need to be redrawn to save time and computation. My MWE is as follows: library(plotly) library(htmlwidgets) g <- ggplot(mtcars, aes(x=mpg, y=cyl)) + geom_point() gP <- ggplotly(g) gP %>%

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, where all the edges are directed from one vertex to another. A directed graph is sometimes called a

I want to color rows in column A by values in column B. The code below is based on the example from the vignette Link , but shows only the condition for two columns: mobile_number by mobile_flag. Data: head(test[, c("EMBG","mobile_number", "home_number", "mobile_flag", "home_number_flag")]) EMBG mobile_number home_number mobile_flag 1 101001455126 075-201-543 02/2446-275 correct 2 101010455015 55555555555 55555555555 incorrect 3 101014455095 0 0 incorrect 4 101947455134 075/482-356 02/2460-020 correct 5 101952450264 070 22 16 18 ---------------- correct 6 101953450012 0 02/2446-276 incorrect
