Notebook-scoped libraries libraries are automatically available on workers for SparkR UDFs. You must reinstall notebook-scoped libraries at the beginning of each session, or whenever the notebook is detached from a cluster. Notebook-scoped libraries do not persist across sessions. Other notebooks attached to the same cluster are not affected. When you install an R notebook-scoped library, only the current notebook and any jobs associated with that notebook have access to that library. Save yourself the trouble installing packages one-by-one all over again.Notebook-scoped R libraries enable you to create and modify custom R environments that are specific to a notebook session. So you now go ahead and install these libraries. We now have a list of libraries that were installed in your previous computer in addition to the R packages already installed when you download R. ToInstall <- setdiff(installedPreviously, baseR) InstalledPreviously <- read.csv('installed_previously.csv')īaseR <- as.ame(installed.packages()) Step 2: Create a list of libraries from your old list that were not already installed when you freshly download R (from your new device). Now copy or e-mail this file to your new device and access it from your working directory in R. This saves information on installed packages in a csv file named installed_previously.csv. Write.csv(installed, 'installed_previously.csv') Installed <- as.ame(installed.packages()) Step 1: Save a list of packages installed in your old computing device (from your old device).
Instead of installing libraries one by one all over again, I did the following: I recently bought a new laptop and began installing essential software all over again, including R of course! And I wanted all the libraries that I had installed in my previous laptop.
