I first need to apologize as I  have made a mistake, I know that I  
should have read the Breaking News before (http://www.sal.uiuc.edu/ 
tools/tools-sum/rgeo/r-spatial-projects)

Now I am trying to step back so that I can retrieve my data. However,  
I don't seem to find old versions of the sp and spdep I need 0.8* of  
sp as I have messed up my objects 'big time'  by upgrading the whole  
installation.

The question is this:

- What is the best method to make up this error? (I'm hoping that I  
am not the only one...)
or
- Is re-installing old versions of the packages the only method?

- Where can I find the repository for old packages?

thanks in advance! Any hint is appreciated

The errors I get are not apparent at first sight... but I later tried  
to retrieve a column of the @data in a SpatialPointsDataFrame object  
and just got >NULL

here's the sequence:

 > pija.scoressp@data[,1]
Error in pija.scoressp@data[, 1] : incorrect number of dimensions
 > pija.scoressp@data$PC1
NULL
 > names(pija.scoressp@data)
NULL

However I can see the data with str():
 > str(pija.scoressp)
