Crash on missing data.
Crash on missing data.

Try
. webuse auto
. svm price mpg rep78
to see this in action (rep78 has scattered missing values).

There have been some attempts to conjoin missing data handling and SVM:
* http://www.cs.toronto.edu/~marlin/research/phd_thesis/marlin-phd-thesis.pdf
* ftp://ftp.esat.kuleuven.be/sista/ida/reports/05-77.pdf
But these deserve their own package, so we will flatly not be handling this case.
