Include the www directory of a shiny app in an R package

[charlott...@gmail.com]

Dear all,

I am trying to build a package containing my shiny app. However, as I have some images in my www directory, I try to include them in this package and I don't know how include this directory (or just images ?) in my package.

I looked at the specific topics of building a shiny app (e.g. http://deanattali.com/2015/04/21/r-package-shiny-app/) but I did not found a topic on the www directory. Moreover, as very few R packages contains images, I thus did not found the solution in other forums than shiny's forum... :'( (e.g. http://stackoverflow.com/questions/28189327/including-images-in-r-package-documentation-rd-files)

Does anyone includes images in its shiny package ?

Thank you very much for your help !!!

Cheers

Charlotte

If you follow the structure that I suggest in my blog post, there shouldn't be any problem if you just put an image in a www/ directory and then refer to it in your app.  I have images in a shiny app inside a package, you can see here: The image lives inside the www/ folder (link) and I refer to it with a single `img(src = "image.png")` (link)

Dear Dean !

Thank you very much for your answer ! I thought that it was cheating to put some additional folders in an R package (I am a beginner at building R package).

But Ok sounds great and it works perfectly !!

Again thank you for you help and congrats for your website, very helpful :)

Cheers !

Dear Dean and others,

After two weeks of thinking, I don't understand how source an image in the code as the working directory is changing with user:

At the beginning, I paste getwd() and the path of the image in the package but when user change WD then it fails:

    output$myImage1 <- renderImage({
      list(src = paste0(getwd(), "/www/1.png"),
           contentType = 'image/png',
           width = 20,
           height = 20,
           alt = "This is alternate text")
    }, deleteFile = FALSE ) # eo output$myImage1

I would need to reach the path of the package within the user computer ? am I right ?

Thank you very much for any help,

Cheers

Use system.file("www/1.png", package="yourpackagename") to find the path to that file in your installed package.

Thank you very much Joe !!

But It raises a problem: In the package, I enclosed the www directory in the package (below man and R directories), but when I build and source the package, the www directory disappears !!!

However, when I open the directory of the installed package of Shiny (as instance) I see that you have well enclosed  a www directory.

Do I need to put the www directory after building the package ?? When do you enclosed this www folder ? After or before building the package ?

Thanks again for your help !

Ok I found the solution,

To enclose additional subdirectories in R package (like www) I think we just have to create a "inst" directory and put the additional folders in it.

Again, thank you very much for your precious help.

Any custom directories you want to include in the package must be under an "inst" directory. For example, "inst/www". At install time this will become simply "www" (the inst folder will be removed and all its children promoted).
