I ran the code like
library(shiny)
library(plotly)
library(dygraphs)
library(htmlwidgets)
path <- getwd()
setwd(path)
ui<-shinyUI(
fluidPage(
titlePanel("Plotly, Dygraphs and R Shiny, save as png"),
sidebarLayout(
sidebarPanel(),
mainPanel(
plotlyOutput("plot_plotly"),
dygraphOutput("plot_dy")
)
)
)
)
server<-shinyServer(function(input, output, session) {
output$plot_plotly <- renderPlotly({
p <- plot_ly(x = c(1,2,3,4), y = c(2,4,1,3), type = 'scatter', mode = 'lines')
export(p, file = "plotlyplot.png")
return(p)
})
output$plot_dy <- renderDygraph({
lungDeaths <- cbind(mdeaths, fdeaths)
q <- dygraph(lungDeaths)
export(q, file = "dygraph.png")
return(q)
})
})
shinyApp(ui,server)

I ran the Code but it doesn't work it gives me an error saying
no applicable method for 'plotly_build' applied to an object of class "c('dygraphs', 'htmlwidget')"
What should I do now. Please let me know...
