could not find function "ggplotly"

[talomvalg]

Hi! I keep getting this error

could not find function "ggplotly"

I have tried to reinstall all packages (plotly, ggplot2 and scales) from their respective github repos, but keep getting the error. I only get the error in markdown and not when I run it in Rstudio.

Any ideas why shiny won't let it run?

`---
title: "Untitled"
output:
flexdashboard::flex_dashboard:
orientation: columns
vertical_layout: fill

runtime: shiny

library(flexdashboard)

Column {data-width=650}

Chart A

plotly::renderPlotly({

  g <- ggplot2::ggplot(faithful, ggplot2::aes(x = eruptions, y = waiting)) +
  ggplot2::stat_density_2d(ggplot2::aes(fill = ..level..), geom = "polygon") + 
  ggplot2::xlim(1, 6) + ggplot2::ylim(40, 100)

  plotly::ggplotly(g)
})

Column {data-width=350}

Chart B

Adding library(plotly) to the top of your file should fix it

I would like to reopen this issue. I am embedding a shiny application in an R package so loading the library before using ggplotly via library(plotly) is not considered good form. Is this something that can be resolved at source?

Check versioning of ggplot2. This is what I got recently:

Error : package 'ggplot2' 2.2.1 is loaded, but >= 3.0.0 is required by 'plotly'
ERROR: lazy loading failed for package 'plotly'
