Techniques for Handling Dependencies Online

When working in a stateless environment, always load required packages at the beginning of each session and consider dependency management scripts.

  • Check the platform documentation for pre-installed libraries
  • Use install.packages() within each session to load additional tools
  • Rely on require() or library() to activate packages post-installation
  1. Create a script (e.g., setup.R) that installs and loads necessary packages
  2. Include it at the start of your project to maintain consistency
  3. Use renv or similar tools if supported by the online platform
Function Purpose Example
install.packages() Download and install a package from CRAN install.packages("ggplot2")
library() Load an installed package into the session library(ggplot2)
require() Conditionally load a package require(ggplot2)
