[R] tackle memory insufficiency for large dataset using save() & load()?

[Gabor Grothendieck]

?save says its the names (not the objects) although I just
tried it and both save(iris, file = "/iris.Rdata") and
save("iris", file = "/iris.Rdata") seemed to work so you are
right that it seems to work with the objects, not just the names,\
although its not documented to do so.

Usage
save(..., list = character(0),
     file = stop("'file' must be specified"),
     ascii = FALSE, version = NULL, envir = parent.frame(),
     compress = !ascii, eval.promises = TRUE)

save.image(file = ".RData", version = NULL, ascii = FALSE,
           compress = !ascii, safe = TRUE)

Arguments
... the names of the objects to be saved.
list A character vector containing the names of objects to be saved.
