I have been using renv on a R project, but now want to remove it from renv versioning, i.e. delete all renv associated files, but still have access to the libraries that I used installed under renv. How do I do this? Alternatively, how do I migrate from renv to packrat?
From RStudio's documentation, link provided by Kevin:
To deactivate renv in a project, use renv::deactivate(). This removes the renv auto-loader from the project .Rprofile, but doesn’t touch any other renv files used in the project. If you’d like to later re-activate renv, you can do so with renv::activate().
To remove renv from a project, use renv::deactivate() to first remove the renv auto-loader from the project .Rprofile, then delete the project’s renv folder and renv.lock lockfile as desired.
If you want to completely remove any installed renv infrastructure components from your entire system, you can do so with the following R code:
root <- renv::paths$root()
unlink(root, recursive = TRUE)
The renv package can then also be uninstalled via:
utils::remove.packages("renv")
Note that if you’ve customized any of renv’s infrastructure paths as described in ?renv::paths, then you’ll need to find and remove those customized folders as well.
Have you tried renv::isolate? That should bring over all the libraries from the renv shared cache into the local project directory? But perhaps that's not what you want to do?

I downloaded a Meteor Starter project called MeteorAdmin.
In the root of its directory tree, you find a packages directory that contains few packages (boostrap, comments, few others) and also, in the .meteor directory there's a file called packages that defines the dependencies of this project.
What is the difference between them? What I found interesting is that .meteor/packages contains bootstrap as well. In theory shouldn't that be enough so that bootstrap would get downloaded to the project?
The meteor packages file simply lists all of the apps dependencies as well as the load order of each (top to bottom). You can edit this file if you know what you are doing, but it's probably better to leave it alone until you are more familiar with Meteor.
The way you add packages is by typing meteor add <package-name> in your terminal and then it will be added to your project. Additionally, the name of the package will be added to the bottom of your packages file.
A meteor app can have local packages that are defined in the packages folder of the root directory. This project likely is implementing it's own bootstrap package and then added it with the meteor command I listed above. Once a local package is added to your project with the meteor add command it's package name will appear in the packages file just like packages from Atmosphere. I hope that answers your question... Let me know if you were looking for something more specific.
I currently have quantmod installed. I would like to modify the source code.
Do I need to uninstall the current version?
I currently was trying
(1) Installed GIT
(2) then I went to New Project>> Version Control >>create a new project form version control GIT and when I click that I get this error
"Git was not detected in the system path. to create projects from GIT repositories you should install GIT and then restart Rstudio. Not tha tif GIT is installed an not on the path then you can specify its location using the options dialog."
(3) So I went to the global options>>GIT/SVN>>Git executable and put this path
C:\Users\me\AppData\Local\Programs\Git\bin\git.exe
(4) then I restarted RSTUDIO and now I get further so when I go to
New Project>> Version Control >>create a new project form version control GIT>>CLONE GIT REPISITORY
Here it asks for a Repository URL, Project Directory name, and Create project as subdirectory of. Here is where I am unsure where I need to put this project so that the modification I make to the quantmod package will be picked up by my version of R
For Repository URL I was going ot put:
https://github.com/joshuaulrich/quantmod
For Project Directory I am unsure: can you advise??
For Create project as sub directory I am unsure: can you advise??
My R libraries are here: C:\Users\me\Documents\R-3.1.2\library
Also currently I have quantmod installed here:
C:\Users\me\Documents\R-3.1.2\library\quantmod
Do I need to uninstall that current version?
Appendix:
On My computer GIT is here: C:\Users\Me\AppData\Local\Programs\Git
On My computer R is here: C:\Users\Me\Documents\R-3.1.2
The project directory is just the name of the folder you will be putting the repo inside. Generally it is the name of package to make things clear. In your case quantmod.
The sub directory you can ignore unless you want to choose some other location (besides the current directory) for you code.
You don't need to uninstall the current version. My usual recommendation is to just increment the subversion of the package in the DESCRIPTION file. For example, increment:
Version: 1.0.1
to
Version: 1.0.2
Now when you rebuild and install you will have the new version. If you need the original again, you can just reinstall the old one (i.e. install.packages). Having both installed at the same time would likely result in conflicts between the packages and just causing a headache.
I installed couple of packages for 'Project A' (e.g bootstrap) assuming that it will be available for all subsequent projects. But when a new meteor project 'Project B' was created, meteor list showed only default packages. So my assumption that meteor packages are like ruby gems available globally is incorrect. As I work offline every now and then, Is there a way I can manually copy/re-use installed packages?
Yes they are similar to gems. Packages are installed in ~/.meteor/packages, in precompiled form. They can be installed globally this way.
When you add a package to your project it will essentially copy the package from there into your build-cache directory hidden in the .meteor directory of your project.
To install a package locally where you can easily re-use it you would have to clone the github repository of the package and place the output in the /packages directory of your Meteor app.
For example for bootstrap, twbs:bootstrap you would clone this reposistory: https://github.com/twbs/bootstrap, into a directory like /packages/twbs:bootstrap (name doesn't matter if its defined in the package.js file on the repository.
In general you can easily re-use a package without the hassle of adding it in manually like so. It's better to use the global packages which are kept up to date.
The trouble comes with being offline. If you use a local package its nearly guaranteed to always work. Whereas the global ones can give a bit of trouble once in a while when you try to add a package in as meteor tries to check the package is up to date, especially where npm packages are involved with the package.
To keep it short if you added a package in using meteor add twbs:bootstrap you should most likely be able to add it to another project using the same command. Only if you keep your packages & meteor up to date.
When developing packages in RStudio.
By default RStudio assume your package directory is the project directory and it looks like that:
But you are allowed to point the package location to a subdirectory of the project directory and it looks like that:
This way you can have some part of your project files, kept in the root project directory, not included in the package. You don't need to set git ignore etc.
But if you want to add RStudio git repo features, you are not allowed to point your git repo in subdirectory, even if you have already created git repo in your package dir (not project dir) you cannot set it in RStudio. I'm stuck at:
Is there any way to enable git repo features in RStudio having git repository in the subdirectory of the RStudio project? Maybe some .Rproj config tweaks?
Very good question. I've experienced the same trouble and it also does not go away with the latest pre-test release. So there's likely no super quick solution to this inside rstudio. Though it might be worth a feature request.
Personally I use the console / git bash with git and rstudio. That is I create a project inside R studio and manually run git init outside rstudio. Also I add, commit, merge, push and pull outside rstudio. If you don't like to manage git via console there's https://windows.github.com/ and https://mac.github.com/ also the folks at Atlassian provide some GUI tool called source tree: https://www.atlassian.com/software/sourcetree/overview
Plus there are many others, like Tortoise Git which I haven't tested, but I think R Studio's current git support is fine for simple things, but a git tool (console or gui) is definitely the way to go if you want to be more flexible.
That being said, sublime text edit is a powerful and easy to hack and customizable text editor which also has quite some packages to extend it. It's not entirely free but sometimes it's a nice supplement to rstudio. And it has a cool resolve conflict package etc.
When running meteor from a git checkout, there are 2 packages available at path
<meteor-path>/packages/non-core
npm-bcrypt/
npm-node-aes-gcm/
How to use/enable these packages (best practise) on own project?
You can use the published versions of your packages already, because they're on Atmosphere:
meteor add npm-bcrypt
If you want to use specifically their git checkout versions, you need to create a packages subdirectory in your app's directory, and symlink there the paths to the packages.
Much easier than symlink is just setting the PACKAGE_DIRS env var. Have a look at https://forums.meteor.com/t/missing-non-core-packages-when-running-meteor-from-checkout/1140 for more details.
