Error in .doLoadActions

I have an Rcpp based R package which when checked by devtool::check() produces following warning:

Error in .doLoadActions(where, attach) : error in load action .A.1 for package tarantoolr: (function (ns) : could not find function "loadModule"

What might be the cause of such behavior and what is the best way to fix this issue?

Full build and check log from travis-ci can be viewed here, warnings are located around lines 1212 and 1223.

Package itself is located at Github.

Try running your package using devtools::check(document = FALSE) as I think your NAMESPACE file is being overwritten and made "empty" as you do not use roxygen2 to create the necessary entries

e.g. You need to create a file called tarantoolr-package.R that contains:

#' @importFrom(Rcpp, evalCpp)
#' @useDynLib(tarantoolr)
#' @exportPattern("^[[:alpha:]]+")
#' @details
#' We all live in a yellow submarine.. 
"_PACKAGE"

Without this file, again, the NAMESPACE file is empty and, thus, the global export of all function via exportPattern("^[[:alpha:]]+") does not occur. Hence, there are no known functions within the environment.
