Attach lubridate

[hammer]

From @hadley on the RStudio Discourse in January 2018:

The real question is why isn’t lubridate in core? The answer is that it currently conflicts (in a narrow sense) with too many base functions - in practice the lubridate functions extend or wrap the base alternatives so the conflict aren’t harmful in practice, but I haven’t had time to think through how this should be indicated in the tidyverse loading screen.

Figured I'd file an issue on GitHub in case there's any loading screen progress to track (that could perhaps be linked to this issue).

This has two components:

• dplyr and lubridate need to share the same definition of union, intersect and setdiff: Conflict between dplyr and lubridate for union, setdiff, intersect lubridate#693

• tidyverse needs to use the conflicted package instead of the current report: Automatically use conflicts #135. This is a fairly big change so I want a bit more time for conflicted in the wild before introducing it.

I second this request: lubridate is critical for working with date and datetime just as stringr is essential for working with chr and forcats is for fct. This would be a good change for many people that routinely work with timestamp data.

I'm trying to install tidyverse locally on a multi-user linux system, but the current version of lubridate requires a more recent version of gcc than is on the system. I was able to download and install the older version of lubridate (v1.6.0), but I can't figure out how to install tidyverse to use that version (using install.packages or devtools::install_github both try to install the current version of lubridate). Is there a way to separate the Tidyverse install from Lubridate so that it can use the older version? Our system admin is gone for a week, so I have no option to update gcc in the near future (and not sure he'll do it anytime soon).

@PAMorin this is off-topic for this issue, since the thread is about whether or not lubridate should be added to the core tidyverse packages (i.e. attached when library(tidyverse) is run).

Could you please ask over on community.rstudio.com?
