I am attempting to prepare a package for submission to the CRAN. In my DESCRIPTION file I include non-CRAN packages in the Depends and Suggests arguments. To tell R where to find the non-CRAN packages, I include the Additional_repositories argument; and I include an .onLoad function at the top of my program (i.e., in 'zzz.R'). I am able to build and check (--as-cran) in RStudio with zero warnings, notes or errors so long as all the Depends and Suggests packages are present. I then use devtools::build() to create a .tar.gz file locally.

To test for a successful local install, I remove the non-CRAN packages from my computer and attempt to install the .tar.gz file that I created. I then get the message:

ERROR: dependency 'smwrQW' is not available for package 'baytrends'

I've read through the

Unfortunately, the above error continues. I'm confident of the url I'm using since the below install.package line works when run independently

install.packages('smwrQW',repos=c("http://owi.usgs.gov/R"),dependencies = TRUE)

The applicable bits of the DESCRIPTION and zzz.R file are below:

  packageStartupMessage("This software program is preliminary or provisional and is subject to revision. ")
}

You cannot have packages from non-standard repos in Depends: or Imports:.

You can have them in Suggests:

Several packages do this; one you could look at is hurricaneexposure which uses this to make a 'too-large-for-CRAN' data package hurricanexposuredata available from a repository created via drat.

So you must move the smwrQR package to Suggests: and then test for it.

Brooke and I have a draft paper (under review) on this which we could send you if you drop us line -- it details all this more than the short answer could.

  • Thanks. I moved smwrQW to Suggests: and got a "Namespace dependencies not required : 'smwrQW'" error. I looked at http://stackoverflow.com/questions/13085481/namespace-dependencies-not-required and moved smwrQW to Imports: . this corrected the build error but left me at same place as original posting. – greengrass62 Mar 15 '17 at 21:02

    You also need to remove it from NAMESPACE. No Depends, no Imports, no NAMESPACE -- only Suggests. – Dirk Eddelbuettel Mar 15 '17 at 21:11
  • I created some other errors. Will restart on a test package and implement your recommendations. – greengrass62 Mar 15 '17 at 21:53
