[Rd] e1071:svm - default epsilon = 0.1 (NOT 0.5) (PR#5671)

[david.meyer at ci.tuwien.ac.at]

Ryszard:

the *package* version (e1071) is relevant here, not the version number  
of R. Actually, the documentation bug you have reported has already  
been fixed in 1.3-14 (which is the current version on CRAN).

Best,

David
