This may be a stupid question, but I'm unable to solve the following issue:
I'm working on a Shiny-app and need an older version of lavaan to obtain the same results as a few weeks ago. I used the following code to install the older version locally: install_version("lavaan",version = "0.5-23.1097"), and I loaded this old version using library(lavaan) into my server.R file. I also added all possible dependencies to my list in the server.R file so that everything works fine locally.
However, when I try to deploy my application, I obtain the following at the end of my task log:

Apparently, it is able to find the old lavaan version and unpack it, but as soon as it performs this lazy loading action, it breaks down.
Does anybody know where I could eliminate this lazy loading or perhaps where to find this quadprog.so or libRblas.so file? I assume that something more essential is going on, but I can't figure it out. Below, you can find my sessionInfo() output.

Many thanks in advance!!
Kind regards
Apparently, my issue had nothing to do with managing package versions. The solution can be found on this link, thanks to Joshua Spiewak.
The gist is that the package quadprog was improperly compiled, although it was successfully installed. Flushing the package from the cache for R 3.4.0 solved the issue.
Thank you all for helping out!
