Or anyone can direct me to some reference to read about? Any help will be highly appricated. Hongsheng [[alternative HTML version deleted]]

Hello! I am doing Principle Componenets Analysis using "psych" package: mypc<-principal(mydata,5,scores=TRUE) However, I was asked to run a case-weighted PCA - using an individual weight for each case. I could use "corr" from "boot" package to calculate the case-weighed intercorrelation matrix. But if I use the intercorrelation matrix as input (instead of the

_______________________________________________________________________________________ Hi, I was just wondering if there was any available R code that could handle general constrained optimisation problems. At the moment I'm using nlminb and optim, both of which allow box constraints on the parameters, but ideally I'd like to be able to specify more general constraints on the solution

Hi all, I'm using Samba 3.0.24-6etch10 in Debian Etch 64bit with kernel Linux 2.6.18-6-amd64.

Thomas, As F Harrel in a preceding message told me that you are the maintainer of Hmisc package, I write directly to you, with copy to the Rhelp list in case someone encountered the same problem and find some benefit in the response. I used quite often the function sas.get in Hmisc library which I is very, very useful. But, as trying to reuse it today it seems not to function anymore. I tried

Full_Name: Hong Ooi Version: 2.10.0 OS: Windows XP Submission from: (NULL) (203.110.235.1) While trying to get summary statistics on a duration variable (the difference between a start and end date), I ran into the following issue. Using summary or quantile (which summary calls) on a difftime object takes an extremely long time if the object is even moderately large. A reproducible example:

The behaviour of within() with list input changes if you delete 2 or more variables, compared to deleting one: l <- list(x=1, y=2, z=3) within(l, { rm(z) }) #$x #[1] 1 # #$y #[1] 2 within(l, { rm(y) rm(z) }) #$x #[1] 1 # #$y #NULL # #$z #NULL When 2 or more variables are deleted, the list entries are instead set to NULL. Is this intended?

If no 'type' is specified, download.packages("pkgname") will download source packages (.tar.gz files), even on Windows. However, the help says type character string, indicate which type of packages: see install.packages. and on Windows, install.packages defaults to downloading binary packages. Is this intended behaviour on the part of download.packages? This is on R

Here is an example where?cbind?fails with an error when?check.names=TRUE?is set. data(airquality) airQualityBind =cbind(airquality,airquality,check.names =TRUE) ?I understand that?cbind?is a call to?data.frame?and the following works: airQualityBind =data.frame(airquality,airquality,check.names =TRUE) but I would like to understand why?cbind?throws an error.
