Leaflet map works in RStudio View, but hangs in browser.

[zlehmann]

Code here:

Column {data-width=600}
-----------------------------------------------------------------------

### Map

```{r}
m <- leaflet() %>% addTiles() %>% setView(lat=25, lng=55, zoom=10)
m

If i add the m lines into the console, I can get the map to display in the Viewer just fine. When I try to knit this code it just hangs with the loading bar running endlessly. I had leaflet map working earlier today, I swear I didn't change any code and suddenly I have these symptoms. No idea what the problem could be. I restarted computer, Moved code to new directory, reinstalled all my packages. Nothing works. I'm new to RStudio so let me know what additional information might be useful.

Hi @zlehmann !

Yes, this is unexpected.

Do you mind sharing the top part of your document? It would be good to have the full yaml header to know what params and document type you used. I'm guessing flexdashboard, but I want to be sure.

[zlehmann]

Hi @schloerke Here is my header:

---
title: "SDE Test"
output: 
  flexdashboard::flex_dashboard:
    orientation: columns
    vertical_layout: fill
runtime: shiny
---
```{r setup, include=FALSE}
library(flexdashboard)
library(tidyverse)
library(leaflet)
library(rgdal)
library(ggmap)
library(httr)
library(leaflet.esri)

options(scipen=999)

I can also confirm that my file works on other machines. It is something specific to my computer apparently.

[schloerke]

Hmmmm. I am getting the forever loading bar as well.

This is specific to RStudio IDE, I believe. If you run rmarkdown::render("FILE.rmd"); browseURL("FILE.html"), it should work as expected.

I'll investigate some more here.

[schloerke]

@zlehmann Inside your RStudio session, may I have the output of sessioninfo::session_info()?

[zlehmann]

If I run rmarkdown::render I get the following pandoc error:

Oh! You're on the bleeding edge / caught us in the middle of package deployments.

There's a hotfix coming out in htmlwidgets. It was submitted last night to CRAN.

To get you moving today, remotes::install_github("ramnathv/htmlwidgets"). Maybe at the end of the week, remove and install from CRAN: remove.packages("htmlwidgets"); install.packages("htmlwidgets").

---

Please install from github and let me know how it works for you.

[zlehmann]

That did it! Thank you so much!

[schloerke]

@zlehmann htmlwidgets 1.5.1 is on CRAN now. 😃
