Hi, first thanks to Sunny Ho (and David James for the pointer) for resolving the problem of the empty rows returned from ROracle.

I am trying to use R interfaced with MySQL. Present goal is that R should calculate the 85% quantile of AvgSpeed for each LinieID.

Hello everybody, could anybody give me a hint how to to use RMySQL and ROracle libraries at the same time without getting conflict with name spaces?

I've been putting together a package that defined generic methods for database access. The packages is called "Rdbi." It borrows as much as possible from existing database packages / proposals. I'd like to start a discussion about the proposed interface. Here's what I've come up with so far: # # Rdbi: connectionMethods.R # dbConnect <- function(dbObj, ...)

Dear R-users, I would like to know if there is a function (in base R or the extension packages) that would automatically detect the break points in a vector x for later use in the cut function. The idea is to determine the boundaries of the n intervals (n>=1) delimiting clusters of data points which could be considered "reasonably" close, given a numerical vector x with unknown
