R : save : save R objects

“save” function writes external representation of objects to a file.  You can read the objects back using “load”, “attach”, “data” functions.

Syntax

save(..., list = character(),

     file = stop("'file' must be specified"),

     ascii = FALSE, version = NULL, envir = parent.frame(),

     compress = isTRUE(!ascii), compression_level,

     eval.promises = TRUE, precheck = TRUE)

If you install “R”, open R console and type ?"save"  to get help for the function save.
