R does have namespaces. Take a look at the NAMESPACE file found at the root of every R package, which defines the symbols and methods exported by the package.

Note for many R packages, the NAMESPACE file is autogenerated from roxygen docs: https://cran.r-project.org/web/packages/roxygen2/vignettes/n...

Which are all dumped into the one single global namespace regardless if you want everything or not.

I can't remember the exact number, but tidyverse package imports literally thousands of things into your global namespace on package load, coupled with any other dependencies and you have a hell of a time figuring out where any function or constant came from.

Calling library() is kind of an antipattern in production R code. You can either call namespaced functions (like say dplyr::mutate()), or use roxygen.

Agreed but the GP isn't wrong. It's much much nicer to import a library with an alias in Python.
