I assume quantreg provides quantiles for the latter, not the former.

Hi, is there a way to bind vectors to DBI query parameters? The

dbGetQuery(c, insert into tst values (?, ?), data.frame(x=c (1,2,1,2),

Is a sequential resolution of seconds required, as per your original post?
If so, then using my approach and specifying the start and end dates and times
will work, with the coercion of the resultant vector to numeric as I included.

Hi,
I would need to get a clarification on a quite fundamental statistics property,
hope expeRts here would not mind if I post that here.
I leant that variance-covariance matrix of the standardized data is equal to
the correlation matrix for the unstandardized data. So I used following data.
Great!

I think the function with the C-like function should do the trick.

I am not quite sure what you are complaining about. The ODBC interface
definition is not vectorized, and that has nothing to do with R... that applies
