diff in a dataframe
...the first row of these columns cannot be computed, but
can I coerce this to happen and assign a missing value there? It would
be really great if I could do that, because in this case I don't have
to re-index my transformed series to the dates again in a new
dataframe.
Thanks in anticipation.

how to play multiple speex audio streams simultaneously

3. Using intermediate server to merge/overlay multiple speex audio streams
encoded at same sampling rate. I can't find an appropriate
function/algorithm in speex code to do so.
Please suggest an appropriate solution.

Factor and Level Issue
...t;a",g="g",c="c",t="t")}
it replaces all the values in the sequence with "a" only. So all columns
become "a". How do I fix this so that the columns retain their original
values but still have 4 levels ie. a,c,g,t.
Thanks a lot for your help,
Vishal

I am not sure though if its really helpful. Above papers mentioned that it
might not be beneficial in itself, but opens up the opportunity for other
optimizations.
Suggestions on this are most welcomed. Waiting for others to pitch in too.

anyone using LARS package in R
...anyone used the "Lars" package in R before? If so, is there any tutorial
(not manual) or worked out example online for this R package that one can go
through to figure out how one can use this package with lasso regression?
I appreciate any help I can get in this direction.
Sincerely,
Vishal

String concatenation, File Path Handling to pass to download.file( ) [backslash in DOS paths]
...again. The code you already suggested would
help me make the date sequence, but I am not sure how I could extract
the mmddyy string from it. Also, I might end up making a list for
dates extending to about 10 years in the past (~2600 working days), so
I was more keen on not creating one long list.

Thanks.

how to play multiple speex audio streams simultaneously
Another approach that I have come across is to decode all speex audio
streams and add their 16 bit signed PCM values clipping values above 2^15-1
and below -2^15. Is this a reliable appproach?
