Fresh install fails without DBI and assertthat packages

[ConorIA]

Hi Gavin,

I just tried installing on a fresh lab computer (i.e. on a fresh library). The install fails complaining that DBI and assertthat are missing. I thought to send a PR, but wasn't sure whether these would be imports or dependencies, so I thought I'd ping you first.

Cheers

It seems this is coming from our importing of the dplyr package. I need to check again, but with changes in tibble we may not need dplyr any longer. Either way, I don't think this is an issue with canadaHCD unless we are specifically using functionality from those packages; installing dplyr should have ensured that the stated packages were installed as those are dependencies of dplyr.

We can't remove the dependency on dplyr until equivalent dplyr::bind_rows() functionality is available in tibble but that may be some time off, see tidyverse/tibble#34.

I have just installed canadaHCD on a very minimal R implementation on Linux (via Docker - specifically https://github.com/ConorIA/dockerfiles/tree/master/alpine-r). There was no such issue. Not sure why I had trouble on Windows but not on Linux (I should mention that I have always used Linux before now, and never had any issue installing canadaHCD). At any rate, this doesn't seem to be canadaHCD's fault, so I will go ahead and close this issue.
