[jira] [Commented] (ARROW-5614) [R] Error: 'install_arrow' is not an exported object from 'namespace:arrow'

    [ https://issues.apache.org/jira/browse/ARROW-5614?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16864333#comment-16864333 ] 

Neal Richardson commented on ARROW-5614:
----------------------------------------

See https://issues.apache.org/jira/browse/ARROW-5555, this is very much a WIP. 

If the package installed but you're being told to call arrow::install_arrow(), that means that at install time, it did not find or link correctly to the C++ library. Check the R package installation output, especially the output from {{configure}} before compilation, for notes of what it tried and what wasn't found.

If you're installing {{ref="76e1bc5dfb9d08e31eddd5cbcc0b1bab934da2c7"}}, that's the 0.13 (unofficial) release point, so that would work if you've installed the C++ library at the 0.13 release point. It won't work with the latest C++ code from apache/arrow master. Likewise, installing the R package from the head of master won't work with the 0.13 C++ library.

> I'm trying to get the R package installed in a Debian docker image that already contains R and RStudio (via rocker/rstudio from dockerhub), as well as arrow-cpp, parquet-cpp and pyarrow installed via conda. I.e. I should have all required arrow dependencies in my conda environment's /lib and /include folders.
> I then tried to install the R package in two ways (as stated in the README, having devtools, and after managing to get git2r installed)
> 1/ via remotes
> {code:java}
> remotes::install_github("apache/arrow/r", ref="76e1bc5dfb9d08e31eddd5cbcc0b1bab934da2c7"){code}
> 2/ from source
> {code:java}
> git clone https://github.com/apache/arrow.git
> cd arrow/r
> R -e 'remotes::install_deps()'
> R CMD INSTALL --configure-vars='INCLUDE_DIR=/root/miniconda/envs/my_env/include    LIB_DIR=/root/miniconda/envs/my_env/lib' .{code}
> In both cases the install seems to work fine:
> {code:java}
> ** building package indices
> ** testing if installed package can be loaded from temporary location
> ** checking absolute paths in shared objects and dynamic libraries
> ** testing if installed package can be loaded from final location
> ** testing if installed package keeps a record of temporary installation path
> * DONE (arrow)
> {code}
>  But when I then do the following as prompted:
> {code:java}
> library(arrow)
> arrow::install_arrow()
> {code}
> The result is
> {code:java}
> Error: 'install_arrow' is not an exported object from 'namespace:arrow'
> {code}
> And running the example without calling that non-existing function I get the error
> {code:java}
> Error in Table__from_dots(dots, schema) : 
>   Cannot call Table__from_dots(). Please use arrow::install_arrow() to install required runtime libraries. 
> {code}
> So I don't know if I'm doing something wrong or if the documentation isn't up to date? Specifically, what is the arrow::install_arrow() function supposed to install, given that I already have the arrow and parquet libs and headers installed, and supposedly they've been used (linked to) when I installed the R package?
> In general, is there any way to get this package installed in the above context (arrow-cpp etc. installed via conda)?
