[Traminer-users] Format of sequences

[Hadrien Commenges]

You could also split your table by set of columns (columns 1:4, then col c(1, 5:7), etc.) and then rbind() all the tables. 

Another option would be the melt() function in the reshape2 package.

Addendum : Do not forget to keep the ID column with the three other columns at each iteration.

Hello Anton, 
An easy solution is to build a very short loop (I know R is not made for loops but it's only 18 iterations) separating each group of three columns, turning the headings into common ones (begin/end/state) and pasting each one below the other. 
I hope that helps,

Hi, 

I have sequences in the following format : 

ID BEGIN1 END1 STATE1 BEGIN2 END2 
STATE2 etc... until 18 
1 01/01/1950 01/01/1960 X 02/01/1960 30/01/1960 
Y ... 
2 01/01/1950 01/01/1960 X 02/01/1960 30/01/1960 
Y ... 

One line = one individual. Successive episodes = successive columns. 

I know that I need to convert dates into numbers: no problem with that. 

However, does anyone have any idea on how I could convert such a df into 
an STS or SPELL format ? 

Thanks! 

Best regards, 

Anton Perdoncin
