[Traminer-users] R crash creating a big event sequence object

[Matthias Studer]

Hi,

I guess that this is related to a memory issue, because of the size of the data. Anyway, all the algorithms implemented in TraMineR cannot deal with long sequences (sequence with more than 3-4 events per sequences). I therefore suggest you look for another software.

Sorry for this answer.
Best,
Matthias

Objet : [Traminer-users] R crash creating a big event sequence object

Hi,

I am experimenting some difficulties when attempting te create a (quite) big event sequence object. My datas contiains 451 sequences, with three events possible, and a sequence length from 10 to 30000. When I launch this code :

library(TraMineRextras)
seq <- seqecreate(id = data$id, timestamp = data$timestamp, event = data$event)

My RStudio session wait some minutes and then crash after "encountering fatal error". I am sorry to not be able to give you more information. Here's my sessionInfo
