| \title{Value of Last Evaluated Expression} |
| \usage{ |
| .Last.value |
| } |
| \description{ |
| The value of the internal evaluation of a top-level \R expression |
| is always assigned to \code{.Last.value} (in \code{package:base}) |
| before further processing (e.g., printing). |
| } |
| \details{ |
| The value of a top-level assignment \emph{is} put in \code{.Last.value}, |
| unlike S. |
| |
| Do not assign to \code{.Last.value} in the workspace, because this |
| will always mask the object of the same name in \code{package:base}. |

| ## 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 |
