CentOS Question posted in
The official documentation can be found here.

R package – Why does tidyr install dependencies not defined in the dependency list? – CentOS

In order to save time, I want to create a docker image with pre-installed R libraries. -> Big Time saving

One part of the Dockerfile looks like this

RUN Rscript -e 'require(devtools); devtools::install_version("dplyr", version="0.5.0", repos = "http://cran.rstudio.com/")'
RUN Rscript -e 'library(dplyr); sessionInfo()'
RUN Rscript -e 'require(devtools); devtools::install_version("ggplot2", version="2.2.1", repos = "http://cran.rstudio.com/")'
RUN Rscript -e 'library(dplyr); sessionInfo()'
RUN Rscript -e 'require(devtools); devtools::install_version("knitr", version="1.15.1", repos = "http://cran.rstudio.com/")'
RUN Rscript -e 'library(dplyr); sessionInfo()'
RUN Rscript -e 'require(devtools); devtools::install_version("tidyr", version="0.6.0", repos = "http://cran.rstudio.com/")

Since this is a production environment, I do not want any surprises. Therefore I want to install the same version of my package every single time, hence the specific versions you can see above.

Now my question: If we look at the DESCRIPTION file of the tidyr package (v0.6.0):
https://github.com/tidyverse/tidyr/blob/v0.6.0/DESCRIPTION

It says:

Imports:
    tibble,
    dplyr (>= 0.4),
    stringi,
    lazyeval,
    magrittr,
    Rcpp

In my system, I have dplyr 0.5.0 already preinstalled, so this shouldn’t trigger an update.

This is my docker output (please note I added sessionInfo() statements to display dplyr versions installed) and as you can see dplyr 0.5.0 is installed on the system, and then tidyr version 0.6.0 forces the installation of dplyr, tidyselect and plogr.

Where does R find these dependancies as they are not in the DESCRIPTION file (and dplyr v0.4.0 >= is already satisfied)?

    Thanks for the previous comment, but I still prefer my old title:

    'R package DESCRIPTION file not respected by R ?' (at least the first part).

    I managed to resolve the issue, which wasn't related to the warning message of rlang or dplyr, but the line below actually automatically upgrades, which seems default behaviour according to Hadley (see https://github.com/r-lib/devtools/issues/863#issuecomment-137241474) 

    RUN Rscript -e 'require(devtools); devtools::install_version("tidyr", version="1.0.0", repos = "http://cran.rstudio.com/"'

    adjusting this line above to add 

    upgrade = 'never'

    (and updating to v1.0.0) actually resolved the issue, as it is now no longer updating packages which are already satisfied. (see new line below)

    RUN Rscript -e 'require(devtools); devtools::install_version("tidyr", version="1.0.0", repos = "http://cran.rstudio.com/", upgrade = "never")'

    I understand this isn't really an 'answer' since it's expected behaviour according to the commenter in the link, but still wanted to post it here for people running into the same problem in the future.

    My main issue is that from a philosophy perspective, I would understand that install.packages() would install the latest version of an R package. But if devtools::install_version() is used, it's likely because you want to install a specific version of software. In that scenario, does it not make sense to NOT upgrade the dependancies ? This links back to the original title, which is that if the dependancies are satisfied according to the DEPENDANCIES file, should R really force an upgrade by default?

    Part of your output tells you the answer

    As of rlang 0.4.0, dplyr must be at least version 0.8.0.

    If you want to use rlang 0.4.0 you need to have at least dplyr 0.8.0.

    Sidenote

    Please use fewer docker layers, especially if this image will be utilized in production. Or squash the layers at the end.

    There is a flag to squash when building your image. It is documented here

    The gist of it

    docker image build --squash -t myimage:mytag .

    For compatibility across various infrastructure setups, I would recommend not to exceed 42 image layers. Here the origin of the statement regarding 42 layers:
