RcppEigen
under the LinkingTo
and not the Imports
headers. I've gotten conflicting instructions and am very confused what to do. I've been learning how to use Eigen myself, so I'm not sure if I did something wrong in writing the functions. I've seen Do I need to import RccpEigen in the DESCRIPTION file for an R package using it, or is "LinkingTo" enough? and understand it should be only under LinkingTo
according to the CRAN manual https://cran.r-project.org/doc/manuals/R-exts.html#:~:text=Specifying%20a%20package%20in%20%E2%80%98LinkingTo%E2%80%99%20suffices%20if%20these%20are%20C/C%2B%2B%20headers%20containing%20source%20code#include <RcppEigen.h>
and letting Rcpp generate the required RcppExports.cpp
filesI've tried testing the package with devtools::check_win_devel()
since that's what CRAN does and got the reply:
"Package in Depends/Imports which should probably only be in LinkingTo: ‘RcppEigen’".
So accordingly, I removed RcppEigen from the Imports
and left it in the LinkingTo
section, but now the package fails the R CMD check --as-cran
with:
"Namespace dependency missing from DESCRIPTION Imports/Depends entries: 'RcppEigen'
See section 'The DESCRIPTION file' in the 'Writing R Extensions' manual."
Is there something wrong with how I'm accessing the Eigen objects?
Thanks to @Roland, I found out that my NAMESPACE had an import(RcppEigen)
in it which was coming from a file along the path R\<packagename>-package.R
that had this in it:
## usethis namespace: start
#' @import RcppEigen
## usethis namespace: end
NULL
By removing the import line, I was able to just put RcppEigen
into LinkingTo
