Restoring an S object that was data-dumped

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).
Correct.  We don't have a description of the S4 (hence S-PLUS 5.x and 6.x) 
data.dump format.  We recommend using data.dump(oldStyle=T) in those 
versions of S-PLUS if possible.

of your desires (at least for this request) is in "library(foreign)".
     hope this helps.      spencer graves

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.
