issues with loading grid?

[HedvigS]

Hi again!

So, normally I load 'grid' but that doesn't work with groundhog.library()

> groundhog.library('grid', '2021-03-14')

groundhog says: FAILED to load 'grid_0.7-1'

I am able to load ggplot2 and gridExtra though, but that doesn't load grid.

I'm probably just missing something obvious. Any ideas :)?

'grid' is now part of base R and cannot be modified (https://cran.r-project.org/web/packages/grid/index.html)

It was last revised in 2002 as a stand-alone package: groundhog::toc('grid')

Will put in the to-do list to include a more informative error for this situation, something like what you would get with this: install.packages('grid')

Thanks for the response

I'm aware that grid is now part of base, I'm just having issues with running a script which utilises grid functions unless I explicitly load grid. It's a bit odd, I'll admit and I'm trying different options. Previously I used pacman for package loading, and I explicitly loaded grid and everything worked fine. It's just breaking now as I'm having to exclude loading grid from the groundhog.library() set up.

Ah, interesting. ok. Right, you want to attach a package that is a base package, that's a scenario I had not considered.

For base packages one cannot do version control beyond sticking to the same version of R, which is something groundhog nudges people into doing with warnings. But right, you may want to attach those packages

For the next release of groundhog I will make it so that if a base package is requested it is loaded locally (whichever version is available, with a warning if there is a mismatch).

In the meantime, if you want to use groundhog, to work with base packages you can either 1) Use :: to explicitly call on the package (e.g., grid::convertX() ) 2) Use library(grid) to attach it.

Until groundhog incorporates this scenario, 1 or 2 will produce the same results and thus, even after groundhog is updated, the code will remain reproducible.

Does this make sense?

It does make sense :)! Thank you.

I think for now I'll just do run of the mill loading with library() for this, seems easiest after all.

Thank you for the help, this is a very nice package and it's great that you're also very responsive here :)
