[Traminer-users] precision in seqdef

[Nicolas S. Mueller]

Dear Nathan,

You could multiply by something large, but this will surely give you 
sequences too long.
What I would do is use the round() function in R to round the timestamps 
to integers.
You could also keep 2 digits and multiply by 100. It depends on the 
precision you need.

Best regards.
