onSessionExit

Registers a function to be called when the R session finishes

Registers a function to be called when the R session finishes.

Usage

# S3 method for default
onSessionExit(fcn, action=c("prepend", "append", "replace"), ...)

Details

Functions registered this way are called when finalizeSession() is called. Moreover, when this package is loaded, the .Last() function is modified such that finalizeSession() is called. However, note that .Last() is not guaranteed to be called when the R session finished. For instance, the user may quit R by calling quit(callLast=FALSE). Moreover, when R is run in batch mode, .Last() is never called.
