Internal Serialization Interface

Internal functions for serialization. See serialize for public (but experimental) versions.

.saveRDS(object, file = "", ascii = FALSE, version = NULL,
         compress = TRUE, refhook = NULL)

.readRDS(file, refhook = NULL)

`object`	R object to serialize.
`file`	a connection or the name of the file where the R object is saved to or read from.
`ascii`	a logical. If `TRUE`, an ASCII representation is written; otherwise (default except for text-mode connections), a more compact binary one is used.
`version`	the workspace format version to use. `NULL` specifies the current default format. The version used from R 0.99.0 to R 1.3.1 was version 1. The default format as from R 1.4.0 is version 2.
`compress`	a logical specifying whether saving to a named file is to use compression. Ignored when `file` is a connection and for workspace format version 1.
`refhook`	a hook function for handling reference objects.

For .readRDS, an R object.

For .saveRDS, NULL invisibly.
