At the risk of ridicule for my deficient linear algebra skills, I ask for help using the solve.QP function to do portfolio optimization. I am trying to following a textbook example and need help converting the problem into the format required by solve.QP. Below is my sample code if anyone is willing to go through it. This problem will not solve because it is not set up properly. I hope I

Using Sweave on Windows (MikTeX 2.5 and R 2.4.1), I've ran into a bit of a problem with the tex -> DVI process. First, I've corrected the common \usepackage error by using \usepackage{"C:/Program Files/R/R-2.4.1/share/texmf/Sweave"} to get around the spacing problem. That is, LaTeX is finding the Sweave.sty, which has been a common problem in past postings here. However, my

I'm using nonparametric regression (packeges ksmooth and ks). My question: is there any way to compute confidence bands (or variability bands) with R. Confidence bands for functions are intervals [CLO(x);CUP(x)] such that with probability 1-alpha the true curve is covered by the band [CLO(x);CUP(x)]. Thanks very much for any help you can offer.

Hi List, Is there an easy way to get a count of the number of active socket connections, or even better, number of socket connections in the time_wait state? (Something lightweight... under /proc/sys/net/ipv4/? I'd like to avoid the impact of listing out all the connections a-la netstat.) Thanks! -Jeff
