[R] Ever see a stata import problem like this?

[John Hendrickx]

I've had a similar problem once. What may have caused the problem
then was a variate for which value lables had been defined for the
highest and lowest values. What complicates things is that the file
had been originally converted from SPSS to Stata. A workaround was to
set "convert.factor=FALSE" and that seems to work here too (using R
1.91 and the latest update for foreign):
