Wow!
I'm going to test this development package, and of course with all precaution for use.
Luckily i have not missing values neither different sequence's lengths in my data...
Thank you very much,
Best,
Elie

Hello TraMineR community!
I work on Optimal Matching Analysis and I'm interested about extensions of the method.
In searching on the Internet, i found that the seqdist function provides methods like "OMloc" for localized optimal matching analysis (like the Hollister proposal), or others methods (duration sensitive OM, etc.).
(For example here)
But this options are not accepted when I use the seqdist function (on the 1.8-9 version of TraMineR package).
I install the development version but the seqdist function still not provide this options.
So my question is: there is these options availables somewhere now?
If not, I would like to create variable indel costs but it seem to be hard to do...
I try to use seqdistmc function with a channel which is my real sequence objet and a new sequence object who give for each position an indicator that taking account neighbouring elements ("0" if all neighbours are others state, "1" if one neighbour is other state and "0" if all neighbours are same state). But I don't think is a good way to do (and it's not conform to the Hollister proposal...)
I thank you for your answers, and I thank a lot all contributors to TraMineR.
Sorry for my english,
Kind regards,

Dear Elie,
Unfortunately, we are a little bit late in our release plan, because some special cases still need some work (such as missing data handling and unequal sequence length for some distances/configurations of parameters).
We have decided to make all these distances measures available in a separate package until the we can merge them in TraMineR. This is a development package, so please note that you may experiences some errors code for some cases.
The package is now available as the seqdist2 library here: https://r-forge.r-project.org/R/?group_id=743
More information about the argument and all the distances can be found in
Studer, Matthias, Ritschard, Gilbert, A comparative review of sequence dissimilarity measures, LIVES Working Paper 2014/33
Best,
Matthias
