Hello,
I try to plot dynamic graphs in a simple dashboard page, here a simple example:
ui.r part
library(shiny) library(ggplot2) library(plotly) library(shinydashboard) ui <- dashboardPage( dashboardHeader(title = "Basic dashboard"), dashboardSidebar(), dashboardBody( fluidRow( plotlyOutput("plot3") ) ) )
and server.r part
server <- function(input, output) { output$plot3 <- renderPlotly({ g <- ggplot(faithful, aes(x = eruptions, y = waiting)) + stat_density_2d(aes(fill = ..level..), geom = "polygon") + xlim(1, 6) + ylim(40, 100) ggplotly(g) }) }
This app renders an error : unable to start PNG device. Do you think is it a problem with my R session and versions of packages ?

Can you recreate the error outside of shiny?
library(plotly) g <- ggplot(faithful, aes(x = eruptions, y = waiting)) + stat_density_2d(aes(fill = ..level..), geom = "polygon") + xlim(1, 6) + ylim(40, 100) ggplotly(g)
Sorry, something went wrong.
