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 request. 

Best regards,

I've a sample of let's say 10.000 individuals and I want to work on subsamples (subsample of women, of students, etc.) with TraMineR. I'd like to know if it's possible to create a stslist object with seqdef for the whole sample (10.000) and make my selections on this object afterwards (in my workflow this would be more efficient), or do I have to create subsamples before using seqdef function ?
