[Traminer-users] how to sort a sequence plot (seqIplot) by more than one variable

[Jan Goebel]

Dear Joel,

the help page on plot.stslist states that sortv has to be a variable name:

    sortv: name of an optional variable used to sort the sequences
           before plotting.

So my guess is, that you have to create a new variable within your data frame and not to supply 
an "external" vector.

However ?seqIplot has in my opinion at least some fuzziness, because here you find:
"The ‘sortv’ argument can be used to pass a vector of numerical values for sorting the 
sequences. See ‘plot.stslist’ for a complete list of optional arguments."

Best wishes,

Jan
