To reproduce:
In RStudio File -> New Project -> New Directory -> R Package
Package name = "temptanic"
This adds a package skeleton with R/hello.R. Running lintr::lint_package() flags a single whitespace lint in hello.R (irrelevant to the issue)
Add an R script to the package that imports the {titanic} package (https://cran.r-project.org/web/packages/titanic/index.html).
# dummy-imports.R
#' @import titanic
#'
NULL
Delete the initial NAMESPACE
Document the package - we see import(titanic) in NAMESPACE
Lint the {temptanic} package:
lintr::lint_package()
.Error in data.frame(pkg = ns, fun = getNamespaceExports(ns), stringsAsFactors = FALSE) :
arguments imply differing number of rows: 1, 0
(The same thing happens whether or not {titanic} is added to {temptanic}::Imports or Suggests)
Note the following:
> getNamespaceExports("titanic")
character(0)
As such, data.frame(pkg = "titanic", fun = getNamespaceExports("titanic"), stringsAsFactors = FALSE) complains due to mismatched argument lengths.
