R help - Jun 2004 - problem with restore and some .RData

Hi,

I have problem with the restore function in some .RData using R 1.9.0
Look the error:

[ronaldo at zeus RAnalise]$ R
...
Error: object 'family' not found whilst loading namespace 'MASS'
Fatal error: unable to restore saved data in .RData

But if I load this .RData with the load() function all objects are recovered.

[ronaldo at zeus RAnalise]$ R --no-restore-data
...
> ls()
character(0)
> load(".RData")
 [1] ".Traceback"               "RespY"                   
 [3] "Trat1"                    "Trat2" 
...
[63] "varied.371.84210116.9"    "varied.371.842101169.5"  
[65] "varied.371.8421011695.12"

All recovered objects work fine. I can use q() and save workspace
image to quit session. But to load this .RData I need to use R with
--no-restore-data option and load the .RData manually.

I try to find the problem, but I dont find this.

Anybody have any idea?

Thanks
Ronaldo

ps. how to initiate R in xemacs with the --no-restore-data option?
    M-x R --no-restore-data dont work

The short answer is to add importFrom(stats, family) to MASS's NAMESPACE 
and reinstall.  Another way is to use

library(stats)

in your .Rprofile in that directory.

The real question is why your .RData is loading namespace MASS.  
Presumably some object in your workspace has MASS in its environment.
Please find out which and tell us exactly how you created it.  (Have you 
copied a MASS object, for example?)
