[Traminer-users] Format of sequences

[Gilbert Ritschard]

You could also consider the HSPELL_to_STS function provided by the TraMineRextras package.

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
