Re: [Rd] CHAR () and Rmpi

2007-09-29 Thread Prof Brian Ripley
I'm not sure what your sticking point here is. If mpi does not modify data in a (char *) pointer, then that really is a (const char *) pointer and the headers are being unhelpful in not telling the compiler that the data are constant. If that is the case you need to use casts to (char *) and

[Rd] as.Date.numeric

I noticed that R 2.7.0 will have as.Date.numeric with a second non-optional origin argument. Frankly I would prefer that it default to the Epoch since its a nuisance to specify but at the very least I think that .Epoch should be provided as a builtin variable.

Greetings R'ers! I have been looking for mathematics libraries for event stream processing / time series simulation. Mathematics libraries for event stream processing require two key features; 1) smart updates (functions use optimal update algorithms, f.ex. once mean is calculated for an event
