renv and approved packages #5
Comments

@jwbowers It ended up taking 2 and a half hours to install the packages. Do you think we should set up renv with a set of packages in the template? Would that help? |

Correct that once you do renv::restore() it does an initial install and doesn't need to do it again unless someone changes a package (like updates it, stops using it --- i.e. removes library(blah) from any file in the repo, or adds a new one). I hate how long it takes on Windows and Linux to install many packages. I don't understand why Window should be slow because they are binaries. (Linux can be slow because it wants to compile them all). The best workaround is that our R Server image has a ton ton ton of packages installed at the outset. Then renv will just copy or symlink to the already installed global packages. So, upon initial image creation there might be need to be a 2 hour window of package installing, but that should only happen once for the whole image --- any other project done using that image should not need to reinstall them. |

Great. Glad I wasn't crazy. At least on this point. If we were to do that with the template, would we still have the two hour package installation when we start a new project from the template? |

I think we'd have the two hour install if the underlying system did not
already have the correct versions of the packages installed. But, if, say,
tidyverse at the right version was installed globally, then it should just
be just symlinking. That said, my experiments about that right now are not
working and it keeps wanting to download and install stuff. There should be
a way to say "Hey renv! We already have tidyverse installed. Ignore the
version! Just copy that one!"

The discussion of Caching here suggests that we should see big speed ups if we can just have all the packages be installed in the image (the VDI, the AWS image, etc..) |

Sadly, I can't get this to work on my machine right now:

I'm leaving this open for now. Basically full use of renv and this template is blocked until we know more about our analysis environments. |
@jwbowers, do you have any thoughts on the interaction between renv and the approved package pool from GSA? I've started a new project from this template. I used a .rmd from another project as a starting point. When I open the file, I get the message that 42 packages need to be installed. I assume that this is because it's using the package environment from renv and not the already installed packages from GSA. My guess is that have I install the packages, I'll be able to call renv::snapshot(), then in the future, I won't need to install all these packages.
Is that right? What do you think?
