<div>Hi Michael,<br>
<br>
Indeed, the solution is to first transform your spell data into
the sts format using seqformat and then to merge it with the
demographic data. Otherwise you get the error message since you
pass as group argument a vector that contains much more rows than
the number of sequences in your sequence object.<br>

I think you don't have to merge your demographic data with your
states/events data, it seems to me that it's the source of your
problem. For my part, I always work with two objects: the
state/event object (sts object) and a dataframe with
individual's id and variables. Try to convert your spell data
without the status variable (educ4), and to get your
individual's data in a separate dataframe. Then you can try :<br>
<br>
seqiplot(data.seq, group = individuals$group, ...)<br>
<br>
Hope it helps.<br>

<b>Objet: </b>[Traminer-users] Problems passing/using group
command<br>
<br>
<p>
Hi All,</p>
<p>
<br>
</p>
<p>
I'm having a problem using the group function in TraMineR. I
have a data set that contains SPELL data, so multiple rows
per case. I also have demographic data per case, at one row
per case. I merge these together and end up with data that
has a demographic covariate per row, so multiple rows per
case. An example of this data would be:</p>
<pre><code><span style="vertical-align:baseline;font-size:13px;margin:0px;border:0px;padding:0px">id startmin stopmin activity educ4

<p>
I have gotten this to work with the example of the mvad data
in the training manual, but I can't seem to get it to work
with the groups, whether I link to the original demographic
data, the merged data, or try to pass the covariates by
seqformat and seqdef. Ideas?</p>
<p>
Thanks,</p>
