How to unload a package without restarting R?

In most cases, you can detach a package in R via detach() instead of restarting your R session. Below is a straightforward approach:

# Syntax
detach("package:some_package", unload = TRUE)

1. detach("package:some_package", unload = TRUE) explicitly unloads the package.
2. Check if it has been removed with search().
3. If you encounter conflicts or unusual behavior, verify whether any other packages you’re using rely on the detached package.

Alternate Approach Using unloadNamespace()
If detaching doesn’t work as expected, you can try:

unloadNamespace("some_package")

Be mindful, though, that unloading might lead to errors if other packages depend on the detached package.
