rprofile | rprofile customisations

It is possible to print messages from .Renviron so it is shown in RStudio at startup?

For example:

What is the simple and elegant way to use renv, venv and jupyterlab with IRkernel together? In particular, how to automatically activate renv from jupyter notebook that is not in the root directory?

I'm embracing a "polyglot" data science style, which means using both python and R in tandem. Now venv is awesome, and renv is awesome, and jupyterlab is awesome, so I'm trying to figure out what is the neat way to use them all together.

I almost have it, so probably a few hints would be enough to finish this setup. Here's where I'm at.

Start with a clean OS, and install system level requirements: R + renv and Python + venv. For example on Ubuntu it would be approximatelly like that:

I would like to set default styles for the plot/matplot functions. For instance, I almost always use

matplot(x, y, type='l', lty='solid', col=rainbow(), lwd=2)

so I would like to set default options of type='l', lty='solid', col=rainbow(), lwd=2 in .Rprofile. Of course, I could just make a new function,

I wrote the docker file like this to deploy the shiny r application

How do I open the help files in the browser instead of the internal Rstudio viewer?

I have ready set the following option options(help_type="html") in .Rprofile

And have added

I am deploying multiple R versions on multiple virtual desktops. I've built 3.6.3 and 4.1.2 R from source on Ubuntu 18.04.3 LTS. None of them finds the system-wide Rprofile.site file in /etc/R or the system certificates in /usr/share/ca-certificates. However R (3.4.4) installed with APT has no such problems. I used Ansible, but for the sake of this question I reproduced the deployment for one host with a shell script.

On Windows 10, I am getting the following error with blogdown::new_site() function:

Hugo has been installed to "C:\Users\hp\AppData\Roaming\Hugo\0.89.4". You are recommended to set options(blogdown.hugo.version = "0.89.4") in the .Rprofile file in your website project. See the blogdown book for more info on .Rprofile: https://bookdown.org/yihui/blogdown/global-options.html

Error: 'system3' is not an exported object from 'namespace:xfun'

I'm wondering what am I missing here? Any hints.

sessionInfo()

I currently have an R project that I created in Rstudio. For this project I created an .Rprofile file. Lately, I've been using JupyterLab to test things, and while I set the same working directory (setwd("~/path/to/project")) as the same as the project I created in RStudio, the R session in JupyterLab doesn't read the project's .Rprofile.

How can share a project's .Rprofile and .Renviron files between RStudio and JupyterLab?

I'm trying to move as many files as possible to be on my D: drive instead of my C: drive, and if possible trying to include RStudio in this, and I'm wondering how much of this is feasible and how painlessly. This includes: version of R, base folder for R, Rstudio, and packages.

Now, since OneDrive was annoying me, I have these packages installed in a custom folder I made (and overwritten the relevant part in Rprofiles, following these instructions and all seems functional for the past few months), so I was hoping that I would be able to uninstall R and Rstudio, reinstall everything in a custom folder in D:, and easily migrate packages.

I'm not too worried about the R and Rstudio but feel a little lost about the most painless way to re-install the packages (which include some non-standard non-CRAN packages) - it seems that there are some answers to these already that suggest it is simple to migrate packages if installed in a custom folder, but they do not include re-installing R or RStudio. Any advice on this would be amazing.
