...e in handy. I tend to keep my data in coma-separated files with a header line. The header line is prefixed with a comment sign '#' to simplify identification of these lines. Now when I read.table the files the '#' is converted to '.' while I want it to be discarded. Thanks, Vadim P.S. I don't know if r-help is the right place for feature requests. If it's not please let me know where the right one is.

...r the vector sizes I use. I want to re-code these functions and I "think" I can come up with a more efficient algorithm. However before I go and reinvent the wheel I wonder if there is a published description of an efficient sampling algorithm with user-specified probabilities?

Dear R-Users, I have a data file with timestamps and I wanted to use POSIXct time data type to represent the respective column. I played around with the type and found a couple of issues: * there seems to be no direct way of reading datetimes into a variable. Let's say this is my file "1992-02-27 23:03:20 PST" "1992-02-27 22:29:56 PST" "1992-01-14 01:03:30 PST"

...pthreads, both mingw flavors produce the same results.

...stion is this: suppose I have a utility function U(a_i, f()), where f() is say a spline. Is there a general optimizer that could find an extremum of such U()? If not, how easy it would be to hack up something like this? Would it become easier if U() depended on f() only, i.e. no a_i terms?

Hi, Having just found an ABI conformance bug in a compiler front-end, I am curious: is the state of target-independent argument lowering in LLVM still the same as when this thread was taking place?: http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-February/thread.html#59387 Vadim -------------- next part -------------- An HTML attachment was scrubbed...

Well, "integer" is also a storage.mode in R. It is not immediately clear which meaning the help page uses. I guess some extra elaboration would be helpful.
