Shiny support for ggmap

[Eric Colson]

does shiny support the functions within the ggmap package?

I can't say I've personally tried it but it seems like it should work if you just use it in a normal renderPlot.

It should just work if you install the ggmap package and then load it in your app.

I can confirm it works fine. I did use it in an app but subsequently replaced it with

gvismap which served my purposes better

It doesn't give me an error, yet it also does not render the image.  Below is the code from the server.R file.  The second line is a function that ultimately renders as map.  Within that function is the call to ggmap and get_map.

Am i using renderPlot appropriately?

     output$myPlot <- renderPlot(

          {test$PlotConditions(cityLat=37.78, cityLon=-122.42, zoom=10, interpolate=TRUE)}

          , width = 800

          , height = 600

      )

Make sure you print() the plot object.

yes, that helped.   However, rather than rending the image it is returning this:

data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAyAAAAJ [... snipped...]

Any ideas?

In ui.R, are you using plotOutput? That's what you want.

Thank you!  That is what i was doing wrong: i was using htmlOutput.  I switched to plotOutput as you suggested and now it works!
