save.image {base} R Documentation

Save R Objects

Description


save.image() is just a short-cut for ‘save my current workspace’,
i.e., save(list = ls(all.names = TRUE), file = ".RData", envir = .GlobalEnv).
It is also what happens with q("yes").

Usage

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

Arguments

file

a (writable binary-mode) connection or the name of the file where the data will be saved (when tilde expansion is done). Must be a file name for save.image or version = 1. [as string]

version

the workspace format version to use. NULL specifies the current default format (2). Version 1 was the default from R 0.99.0 to R 1.3.1 and version 2 from R 1.4.0. Version 3 is supported from R 3.5.0. [as string]

ascii

if TRUE, an ASCII representation of the data is written. The default value of ascii is FALSE which leads to a binary file being written. If NA and version >= 2, a different ASCII representation is used which writes double/complex numbers as binary fractions. [as boolean]

compress

logical Or character string specifying whether saving to a named file Is to use compression. TRUE corresponds to gzip compression, And character strings "gzip", "bzip2" Or "xz" specify the type of compression. Ignored when file Is a connection And for workspace format version 1.

safe

logical. If TRUE, a temporary file is used for creating the saved workspace. The temporary file is renamed to file if the save succeeds. This preserves an existing workspace file if the save fails, but at the cost of using extra disk space during the save. [as boolean]

envir

environment to search for objects to be saved. [as Environment]
