I wonder if anyone can help me with a travisCI build for an R package I’m writing, named ‘argoFloats’, that uses the ‘shiny’ package.

A sample failed build is at [https://travis-ci.org/github/ArgoCanada/argoFloats/builds/728933817](https://travis-ci.org/github/ArgoCanada/argoFloats/builds/728933817)

Near the end, the transcript says that it cannot load ‘shiny’, but earlier on, I see that its source was downloaded and built without difficulty. These steps are detailed more in the snippets below, from the above-stated URL.

_Snippet 1 from log_

```auto

_Snippet 2 from log_

```auto

```

_Snippet 3 from log_

```auto
    Error in loadNamespace(name) : there is no package called ‘shiny’

```

Try installing the `devtools` package from CRAN and use `install_dev("package name"`). See if that changes anything for you.

I know this is an imposition, but is there any chance of a hint on doing these two things? I find travisCI a bit mystifying, and have been fiddling with different ways to install `devtools` within my yml file. Listing it in `r_packages` does not seem to make it available to a `install:` item that I tried adding. At the moment I have as below, but I’m basically just making guesses and, I fear, wasting watt-hours on the travisCI servers.

```auto

Your package has shiny only in `Suggests` but uses it as a build time dependency ([https://github.com/ArgoCanada/argoFloats/blob/dda076c35abedb395395e65fcde1b7ab747b1512/R/mapApp.R#L14](https://github.com/ArgoCanada/argoFloats/blob/dda076c35abedb395395e65fcde1b7ab747b1512/R/mapApp.R#L14)).

You need to put shiny in `Imports`.

Thanks, @jimhester. I’ve got it working now. I appreciate the help. Dan.
