Examples

## make some objects
aMatrix <- diag(10)
letters <- c("a", "b", "c")

## save the session
sessionFile <- tempfile(fileext=".rbin")
saveSession(list = ls(), file = sessionFile)

## create an environment where they can be restored
env <- new.env()

## define an S4 class
setClass("foo", where = env)

## restore the objects leaving "goo"
restoreClassDefinitions(file = sessionFile, envir = env, clean = FALSE)
ls(env)

## restore the objects again, this time delete all objects from env first
restoreClassDefinitions(file = sessionFile, envir = env, clean = TRUE)
ls(env)
