Read an S3 Binary or data.dump File
Reads binary data files or data.dump files that were produced
in S version 3.
data.restore(file, print = FALSE, verbose = FALSE, env = .GlobalEnv) read.S(file)
file |
the filename of the S-PLUS |
print |
whether to print the name of each object as read from the file. |
verbose |
whether to print the name of every subitem within each object. |
env |
environment within which to create the restored object(s). |
read.S can read the binary files produced in some older
versions of S-PLUS on either Windows (versions 3.x, 4.x, 2000) or Unix
(version 3.x with 4 byte integers). It automatically detects whether
the file was produced on a big- or little-endian machine and adapts
itself accordingly.
data.restore can read a similar range of files produced by
data.dump and for newer versions of S-PLUS, those from
data.dump(....., oldStyle=TRUE).
Not all S3 objects can be handled in the current version. The most frequently encountered exceptions are functions and expressions; you will also have trouble with objects that contain model formulas. In particular, comments will be lost from function bodies, and the argument lists of functions will often be changed.
For read.S, an R version of the S3 object.
For data.restore, the name of the file.

## Not run: read.S(file.path("_Data", "myobj"))
data.restore("dumpdata", print = TRUE)
