Dear Hadrien,

You can select rows of sequence object using subscripts. The following 
example first creates a sequence object for the whole mvad data set and 
then creates separate sequence objects for males and females using the 
"male" variable in the mvad data frame.

mvad.seq <- seqdef(mvad, 17:86)

mvad.male.seq <- mvad.seq[mvad$male=="yes",]

mvad.female.seq <- mvad.seq[mvad$male=="no",]

By the way: It appears that you are not registered as a traminer-users 
list member. It is much easier for us if you register before sending 
questions to the mailing list. Otherwise we have to manually accept your 

Best regards,
