Please never guess, it only misleads you and readers of your posting.

Please always state the output of sessionInfo() - we don't know which 
version of splm you are using.

Please always include a reproducible example of the code leading to the 
error with a built in data set.

Do check that the problem is not already resolved in the development 
version on R-forge, here:

Finally, do not post HTML, much of the extensive carbon footprint of lists 
like this comes from scanning HTML postings for unwanted and/or dangerous 
payloads.

Hope this helps,
