Hi R users and developers on debian platforms. I compile the R version 2.8.1 Patched (2009-03-18 r48193) on my UBUNTU linux distribution. But when I ask for the aggregate example it fails. What am I missing? example(aggregate) aggrgt> ## Compute the averages for the variables in 'state.x77',grouped aggrgt> ## according to the region (Northeast, South, North Central,West) that aggr...

...) But if you modify it in this way, it works!: aggregate(state.x77, list(Region = state.region), function(x) mean(x) ) Is it necesary to change the example? What is changing in aggregate() function? Thank you for your attention.
