1. Could you upgrade to the latest version of R (1.8.1)? I don't know if it will help, but it might.

2. I just used Notepad to open a data.dump file created in S-Plus 6.2. It started, "## Dump S Version 4 Dump ##". How does your data.dump file begin?

3. If you upgrade and can't solve the problem any other way, you could list out the "data.dump" code and step through it one line at a time until you identify the problem and a way to fix it -- at least in your case. A "data.dump" file seems to be plain text, which means that it can be modified in a text editor, provided you know what to change.

hope this helps. spencer graves

Obviously, it was data.restore() that produced the error below. However, I think S-PLUS 5 might not be supported by data.restore() in the `foreign' package since the docs there say it can only read objects from S-PLUS versions 3.x and 4.x (on Unix).

Have you tried 'help.search("data.restore")' or the "posting guide" at "http://www.R-project.org/posting-guide.html";? I believe the object of your desires (at least for this request) is in "library(foreign)".

Hi:

In R, how can I "data.restore" an object that was "data.dump"ed in Splus (I am not sure of the exact version, but probably Splus5)? When I use data.restore, I get the following error message (I am using R 1.7.0 on Windows)



data.restore("n2.suicide")


Error in ReadSdump(TRUE, " ") : S mode " "Netherlands", "Ireland", "Denmark", "Norway", " Sweden", "Finland"," (near byte offset 230) not supported
In addition: Warning message: NAs introduced by coercion


Thanks for any help,
Ravi.
