Would be nice to keep the list and the progress on github.<br>
Other might pitch in and help out, I am also interested, just don't know<br>
how much time I can spend on it.<br>
<br>
Kind regards,<br>

Nice!<br>
<br>
Worth noting that the R version gets better the second time.<br>
I guess R keeps<br>
its hash table somewhere.<br>

PS. Would you be interested in a set of R functions that from a<br>
quick<br>
skim of the R sources that I think could be much much faster if<br>
implemented in Rcpp?<br>
<br>
<br>
Sure. Time I have available will decide what I do of the list ^^.<br>
