 What's the right way to create a Clojure function that returns a new sequence based on another sequence?

it fixes the issue The short answer: remove all the references to lazy-seq. as for your original question, it is worth explaining even if it's not a idomatic use of lazy-seq. you have to use first because the get-word-ids function is returning a lazy sequence with one entry. that entry is the lazy sequences you are looking for. code :
( (word1 word2 word3) )
(word1 word2 word3)
(lazy-seq (cons :something (function-call :produces :the :next :element)))

 How to create sequence index plots of a subset of groups in a sequence object?

With these it helps You can use a subset by indexing the state sequence object and the grouping variable. If you have a state sequence object called "myseq", a subset vector called "subset" and the data frame where your group variable is stored called "my.data.frame": code :
seqIplot(myseq[subset, ], group=my.data.frame$mygroup[subset])
subset <- my.data.frame$mygroup %in% levels(my.data.frame$mygroup)[1:2]
subset <- my.data.frame$mygroup %in% c("value1", "value2")

 How do I create an Rx sequence by running tasks over original sequence's values?

I wish did fix the issue. I have a sequence of type IObservable and a function that maps T, CancellationToken to a Task. What's the cleanest way of getting an IObservable out of them? , This seems to work for me so far: code :
public static IObservable<U> Select<T, U> (
this IObservable<T> source,
Func<T, CancellationToken, Task<U>> selector)
{
return source
.Select (item =>
Observable.Defer (() =>
Observable.StartAsync (ct => selector (item, ct))
.Catch (Observable.Empty<U> ())
))
.Concat ();
}
public virtual IObservable<TResult> SelectMany<TSource, TTaskResult, TResult> (IObservable<TSource> source, Func<TSource, CancellationToken, Task<TTaskResult>> taskSelector, Func<TSource, TTaskResult, TResult> resultSelector)
{
return SelectMany_<TSource, TTaskResult, TResult> (
source,
x => FromAsync (ct => taskSelector (x, ct)),
resultSelector
);
}
public virtual IObservable<TResult> FromAsync<TResult> (Func<CancellationToken, Task<TResult>> functionAsync)
{
return Defer (() => StartAsync (functionAsync));
}

How to create real time order book since Poloniex exchange WAMP Api sequence number is not correlating with the sequence

Hope that helps I have the same problem. Seems they have some bug. What I have noticed is that there are different sequences sent in normal update messages and in "heartbeat" messages (the ones without payload). The documentation states that a heartbeat message should repeat the last normal message sequence number. But it differs. However it corresponds to a number returned by REST API. So seems that "works" for heartbeat messages and wrong for normal ones. Looks pretty much as a bug. Here is also some related question.
