View source: R/detach_nonstandard_packages.R

Detaches non standard packages for a (fairly) clean initialization at the start of an interactive script.

detach_nonstandard_packages(
  standard_packages = c("stats", "graphics", "grDevices", "utils", "datasets",
    "methods", "base", "tools", "Rcpp"),
  standard_namespaces = c("tools", "Rcpp", "data.table"),
  detach_namespaces = FALSE
)

`standard_packages`	Vector of packages considered to be "standard" and not detached. The default value is c('stats', 'graphics', 'grDevices', 'utils', 'datasets', 'methods', 'base', 'tools', 'Rcpp') Although Rcpp isn't "standard", it can't be detached.
`standard_namespaces`	Vector of standard namepaces NOT IMPLEMENTED These are namespaces that you want to keep, if you are detaching namespaces; i.e. (if detach_namespaces == TRUE) The default value is c('tools', 'Rcpp', 'data.table')
`detach_namespaces`	Do you want to detach name spaces? NOT IMPLEMENTED Default value is FALSE

This would be better if you could detach namespaces, but you really can't. Even though the logic pretty much exists, there issues with unloading DLLs in Windows and similar complications in non-Windows systems.

The best way to detach namespaces is to restart R, which in R Studio is quite easy; just select your current project again in the upper right hand corner of the application and you'll be back where you were with a clean R instance.

To see the full list of attached namespaces and pacakges run sessionInfo(). Load some pacakges first to see a decent example, such as ggplot2, data.table, or caret.
