Issues building and installing a created R package - r

Question

I have created an R package (not yet on CRAN) and sent it to a colleague (as a .zip file).
Unfortunately, they were unable to properly build/install it without R throwing an error.
The error received was:
Error: Command failed (1)
In addition: Warning message:
The following packages are referenced using Rcpp::depends attributes however are not listed in the Depends, Imports or LinkingTo fields of the package DESCRIPTION file: RcppProgress
To create the package, I used the RcppArmadillo.package.skeleton() function in R v. 3.4.3.
I works for me, but not for my colleague.
My method in building/installing is:
build("package name") # creates a .tar.gz file
install("package name")
Would simply sending the .tar.gz file to my colleague and simply running install() work?
Here is the DESCRIPTION file:

Answer 1

The error is
The following packages are referenced using Rcpp::depends attributes \
however are not listed in the Depends, Imports or LinkingTo fields of\
the package DESCRIPTION file: RcppProgress
which seems plausible given what you now posted for DESCRIPTION and NAMESPACE.
So here is what I would do:
Create the package using the skeleton generator as you have. Extend as neeed as you have. Then ...
Run R CMD build mypackage then
Run R CME check mypackage_1.2.3.tar.gz
This should give you a clear idea as to whether your sources are in good shape. After that, you can create a binary or zip or ... which your colleague should be able to utilise.
Edit: And you should of course grep for RcppProgress upon which you may indeed have an undeclared dependency.
