Hi, I have submitted a package to CRAN in ftp://ftp.tuwien.ac.at/incoming/pastecs_1.0.tar.gz. The R extension manual advises to send a mail to cran at ci.tuwien.ac.at about it, but it fails. I have also tried WWWadmin at ci.tuwien.ac.at. Are these email adresses still valid?

...could be a useful addition, because it is tricky to edit the metafile, ungroup de elements, select the background rectangle, delete it, regroup all the other elements and save the graph in a graphic pachage just to get transparent background on the graph... This could be simply bg=False. Thanks, Philippe Grosjean P.S.: I really appreciate the changes made to exported graphs in R to correct the bug in MS Word 2000 (some metafiles are not correctly displayed on screen in Word 2000 for Windows). It is amazing that the R-team find a workaround for this Micro$oft bug... and in the meanwhile, Micro$oft...

Hi all, I have a bit of a newbie question here that I hope y'all can help with. I've run a cluster analysis using hclust on about 500 objects (using R1.3 under Win 2000). The problem is that the tips of the dendrogram are so close together on the plot that the labels overlap and are unreadable. I've used "cex" to reduce the label sizes but this isn't sufficient with so

Dear R and S users, I've been working on fitting finite mixture of negative exponential distributions using maximum likelihood based on the example given in MASS. So far I had much success in fitting two components. The problem started when I tried to extend the procedure to fit three components. More specifically, likelihood = sum( ln(c1*exp(-x/lambda1)/lambda1 + c2*exp(-x/lambda2)/lambda2

Hi, I need help regarding estimating a linear model where restrictions are imposed on the coefficients. An example is as follows: Y_{t+2}=a1Y_{t+1} + a2 Y_t + b x_t + e_t restriction a1+ a2 =1 Is there a function or a package that can estimate the coefficient of a model like this? I want to estimate the coefficients rather than test them. Thank you for your help Ahmad Abu Hammour --------------

Colleagues ---------------------------------- System info: Version 1.2.3 (2001-04-26) on NT ESS v. 5.1.18 using emacs ver. 20.4 ---------------------------------- I am wondering if there is a problem with the function rep(). Both the commands using rep() below were expected to produce 8 twos, but only the second did. x <- rep(2,40*(1-0.8)) length(x) y <- rep(2,40*0.2) length(y)

Hi there, I've got this vector: -84 -87 -90 -90 -89 -86 NA NA NA NA NA NA NA NA NA NA NA NA -96 -99 -100 -99 -96 -92 -89 -87 -87 -88 -90 -92 -94 -95 -96 -97 -97 -97 -96 -95 Is there a function in R which replaces the NAs with "interpolated" values between -86 and -96? Thanks, Sven

Let A be a m by n matrix and b a length n vector. What is the fastest vectorized code for doing for(j in 1:n) A[, j] <- A[, j]/b[j] ? solution 1: t(t(A)/b) solution 2: B <- matrix( rep(b, m), byrow=T, nrow=m ) A/B anything else? I have a program that uses this kind of operation million of times and I appreciate your input. Thanks. Jason Liao ===== Jason G. Liao Department of
