[Traminer-users] Traminer-users Digest, Vol 37, Issue 3

[Jeremy Reynolds]

Hi Gilbert,

Thank you for your response.  After more experimenting, I have found that
(as suspected) the error must be on my side.  I am not sure exactly what I
did wrong.  I think my mistake was either a sloppy use of the aggregation
feature in the weighted cluster package or an inappropriate use of the
subset() function when I created the separate data set.  In any case, I now
get sequence index and distribution plots that look the same whether I use
the group option or make the plots separately after sub-setting the data.

Jeremy
