I see no problem here. Annual data from 1910 to 2009 are correctly shown.
(Gretl from CVS with Ubuntu 12.04).
I think it depends on the R version. In R 3.1.0 there's a "new feature"
(in fact, a backwardly incompatible change) described as follows:
"type.convert() (and hence by default read.table()) returns a character
vector or factor when representing a numeric input as a double would lose
accuracy."
So if we happen to print data for consumption by R with more than (I
suppose) 16 significant digits it gets silently borked.
