[R] Building Packages.

[Jorgen Harmse]

Thank you. tools:::.install_packages works.

It happens that one of the functions in my package is a utility to build packages. I guess I should change the install step.

Regards,
Jorgen.



#' Build package from source

#'

#' \code{roxygen2} & \code{devtools} have several steps to build a package, and

#' \code{build.package} wraps them in one function. It can also clean up

#' and protect the description file.

#'

#' @param package.dir the directory with the package files arranged as expected by

#' \code{roxygen2} except as noted below

#' @param clean whether to remove old \code{Rd} files before starting

#' @param install whether to install the package after building it, which may make the latest

#' version available in the current R session

#'

#' @note The description file should be in \code{DESC.source} rather than \code{DESCRIPTION}.

#' \code{build.package} will then overwrite the machine-generated \code{DESCRIPTION} from the

#' previous build with the true source.

#'

#' @return \code{invisible()}

#'

#' @export



build.package <- function(package.dir,clean=TRUE,install=TRUE)

{ if (!require(roxygen2))

    stop("Please install roxygen2 and its dependencies.")

  if (!require(devtools))

    stop("Please install devtools and its dependencies.")

  if ( file.exists(file.path(package.dir,"DESC.source") -> DESC.source) )

    file.copy(DESC.source, file.path(package.dir,"DESCRIPTION"), overwrite=TRUE)

  roxygenise(package.dir,clean=clean)

  tar <- devtools::build(package.dir)

  if (install)

    install.packages(tar,type='source',repos=NULL)

  invisible()

}

Sorry, then it has been my mistake to blame RStudio for this.

We can try debugging this. If you start a fresh R process and run
tools:::.install_packages(path_to_tarball), the installation will (try
to) proceed in the current process instead of a child process. Once it
fails, traceback() will be available to show you where the error
condition has been raised. What does it say?

Alternatively,

1. Check the package R files for stray library() calls. Generally,
packages should not be calling library().

2. Try a "binary search" approach. Make a copy of your package code but
remove half of the files (or half of the functions if they live in a
single file). Keep removing a half (or go to the other half) depending
on whether the same error keeps happening.

Good luck!
