Having worked with optim() and related programs for years, it surprised me that I haven't noticed this before, but optim() is inconsistent in how it deals with bounds constraints specified at infinity. Here's an example: # optim-glitch-Ex.R x0<-c(1,2,3,4) fnt <- function(x, fscale=10){ yy <- length(x):1 val <- sum((yy*x)^2)*fscale } grt <- function(x, fscale=10){ nn

I'm wondering how to save an object (models like lm, loess, etc) in a DB to retrieve and use it afterwards, an example: wind_ms <- abs(rnorm(24*30)*4+8) air_kgm3 <- rnorm(24*30, 0.1)*0.1 + 1.1 wind_dg <- rnorm(24*30) * 360/7 ms <- c(0:25) kw_mm92 <- c(0,0,0,20,94,205,391,645,979,1375,1795,2000,2040) kw_mm92 <- c(kw_mm92, rep(2050, length(ms)-length(kw_mm92))) modelspline

Given a freshly produced quantreg.Rcheck directory, I was able to reproduce this crash by running R -d gdb # make

Gurus: I have a new version of my quantreg package with minimal changes, mainly to fix some obscure fortran problems. It fails R CMD check ?as-cran with the error: Running examples in ?quantreg-Ex.R? failed The error most likely occurred in: > base::assign(".ptime", proc.time(), pos = "CheckExEnv") > ### Name: plot.rqss > ### Title: Plot Method for rqss Objects

This message was sent to bugtraq today: While playing around with FreeBSD 5.4 and jailing I discovered that it was possible to put an ethernet interface into promiscious mode from within the jailed environment, allowing a packetsniffer to gather data not meant for the jailed box. This also affects FreeBSD 5.3 (tested) but not FreeBSD 4.x This can be reproduced on boxes where BPF support is

Hi, Can somebody maybe explain to me why there is a (huge) difference between the default samba package in ubuntu trusty (4.1.6) and the from source compiled stable version. I cannot find the reason why the ubuntu version is so much faster when doing a move (50 items p/sec) of a bunch of files and doing the same move on the compiled version of samba (2 items p/sec).
