Jupyter and R Troubleshooting

Error loading packages in Jupyter

Example Error:

Error in library(ggplot2): there is no package called ‘ggplot2’

Common Issue: The package isn’t installed in the correct location.

Solution:

1. Check Library Location:

   • Run Library() in R to see the location of the library and the installed packages.

2. Common Library Locations:

   • /Users/username/Library/R/3.2/library
   • /Library/Frameworks/R.framework/Versions/3.2/Resources/library

3. Verify Package Installation:

   • If your package isn’t listed, it means it’s not installed in the R library that Jupyter is using.

4. Install Package:

   • Open R or RStudio.
   • Run the following command, replacing PACKAGENAME with the package you’re trying to install and /Path/to/Library with your library location (found using Library())

install.packages("PACKAGENAME", lib="/Path/to/Library")

Example:

install.packages("ggplot2", lib="/Users/username/Library/R/3.2/library/")
