I am experimenting with creating a distance matrix between time series for clustering and similarity searching. The main reference I am using is for the Similarity procedure in SAS (Paper). I would like to conduct the analysis in R using the dtw package.

What I am confused about it the application of DTW to series of different lengths.

1) Is this possible? 2) Any hints on how to do it with the R package?

Regarding question #2, trying to calculate a distance matrix on a matrix of series that differ in length immediately fails:

dist_mat<-dist(appliances_t,method="DTW")

Error in dtw(distance.only = TRUE, ...) : 
  No warping paths exists that is allowed by costraints

dput(appliances_t)

This feels like a hack, but I can get the dtw function to work as follows. 

#this shows how to register a distance function with proxy

install.packages("proxy")
require("proxy")


DWT.DIST<-function (x,y)
{

  a<-na.omit(x)
  b<-na.omit(y)

  return(dtw(a,b)$normalizedDistance)
}


## create a new entry in the registry with two aliases
pr_DB$set_entry(FUN = DWT.DIST, names = c("DWT.DIST"))

d<-dist(appliances_t, method = "DWT.DIST")
hc<-hclust(d,"ave")
plot(hc)

pr_DB$delete_entry("DWT.DIST")

    $\begingroup$ I received confirmation from the package author that this is indeed the properly method to use to deal with series of differing lengths (to obtain a distance matrix). $\endgroup$ – B_Miner May 13 '13 at 12:55

It looks like you should be using the open.end=TRUE flag to enable variable-length matching, but unfortunately I still get errors.
