base (version 3.3)

Last.value: Value of Last Evaluated Expression

Description

The value of the internal evaluation of a top-level R expression is always assigned to .Last.value (in package:base) before further processing (e.g., printing).

Usage

.Last.value

Details

The value of a top-level assignment is put in .Last.value, unlike S.

Do not assign to .Last.value in the workspace, because this will always mask the object of the same name in package:base.

Examples

## These will not work correctly from example(),
## but they will in make check or if pasted in,
## as example() does not run them at the top level
gamma(1:15)          # think of some intensive calculation...
fac14 <- .Last.value # keep them

library("splines") # returns invisibly
.Last.value    # shows what library(.) above returned
