I was wondering if someone could help me with a problem getting locfit running. I am running Digital Unix 3.2D on an alphastation, with R 0.61.1 I downloaded the CRAN distribution of locfit. I had no problems installing it with R INSTALL (I installed it into my library rather than the default base library; the output is attached at the end of this email message). I then tried to test it with the

I have a question regarding the package LOCFIT of C Loader. After fitting a smooth surface (y modeled by two regressors), I can't seem to find a nice way of making a perspective (or other 3d plot). The contours don't look quite so good. It is meant to be used as illustration of smoothing to my students in regression analysis. Could anybody perhaps assist me in producing a

I am trying to reproduce Figure 10.5 of Loader's book: Local Regression and Likelihood. The code provided in the book does not seem to work. I have managed (a while ago) to get the accompanied R-code for the figures in the book (file called lffigs.R) from somewhere - cannot find it on the web anymore. The code in the .R script file does not work either. Could anybody please direct me in

Hello! In the book Modern Applied Statistics with S (4th ed), section 5.6 the concept of the "average shifted histogram" or ASH is mentionend. Also it is mentioned in the same section "The code used is in the scripts for this chapter" (from figure caption 5.8, analysis of the geyser duration data). *However*, I have trouble finding the code for that function! Admittedly, I am a

Hi R-help I have some question. First I have data in Excle ,then I would like to fit distribution from this data, how to import this data from excle? What's command? Thaks for first answer Second I learn R program from The Basics of S and S-plus book because it's basic, and then when I use command is attact(geyser) [follow from book] but I can't . Because it's command only S

Hi Is it possible to use the rep command (or maybe some other "shortcut") to create a vector with the following format: 4 3 4 2 3 4 1 2 3 4 Any help is much appreciated.

Hi I have installed the new version 2.7.1, and get the following messages. Is there some way I can "fix it" ? I use SciViews as well, so the problem may be with one of the libraries that is loaded at start-up: Start-up: Loading required package: datasets Loading required package: utils Loading required package: grDevices Loading required package: graphics Loading required package:

Hallo Is there an elegant way to do the following: Dataset consists of 2 variables: var1: some measurements, and var2: a grouping variable with two values, 1 and 2. There are (say) 10 measurements from group 1 and 15 measurements from group 2. The idea is to study the permutation distribution of mean(group 1) * mean(group2). One way would be to permute 1s and 2s and select the corresponding

Hello, we have a mixed environment at work: CentOS + Win2003 servers. The Win2k3 part contains: AD, DNS (inlc. dyndns), DHCP, DFS, Exchange. The CentOS part: NIS passwords + also a DNS server. So currently we have to update the Linux DNS server zone infos by hand: I export a text file from Windows DNS server and then edit it around using vim. On the Windows side however it's easy for me to

I hope somebody can help. A student of mine is doing a study on Measurement Error models (errors-in-variables, total least squares, etc.). I have an old reference to a "multi archive" that contains leiv3: Programs for best line fitting with errors in both coordinates. (The date is October 1989, by B.D. Ripley et al.) I have done a search for something similar in R withour success. Has

Dear UseRs I would like to show my students how to use "resampling" to solve the following simple problem: If a family has two children of which one is a boy, what is the probability that the other child is also a boy. The answer is (obviously) 1/3, and can be show easily using the usual methods. But I would like to get the students to think of resampling, by doing the following:

Hi Ulrich, thanks for the suggestion. My concern is that one of the valid inputs is "2.5", which would require conversion to an int, e.g. x10, but doing something like this would start to affect the code readability.

Hi I think there was a built-in function (perhaps C-code) called "band_den_bin" in the base library (used for kernel density estimators). Is there a newer version of this function. I have an old routine using this but it won't run in the newer version of R. Any help is much appreciated. Jacob Jacob L van Wyk Dept of Statistics University of Johannesburg, APK Campus Box

Hi I have 3 vectors, say g1, g2 and f, where g1 and g2 contain the row and column indices of a matrix, with corresponding elements in f. How can I create a matrix containing the values in f ? For example: g1 g2 f 3 4 10 2 1 30 4 4 50 How can then get a matrix that looks as follows: 0 0 0 0 30 0 0 0 0 0 0 10 0 0 0 50 I am still learning R. I think reshape will

Hi I run R in Windows. Is there a simple way of changing the prompt symbol ">" to, say, "R>" ? (Not just for a temporary session, but every time R command window is opened.) The documentation of doing this is rather "sparse". Much appreciated for your assistance. Jacob Jacob L van Wyk Department of Statistics University of Johannesburg, APK P O Box 524

Attached is the amended second patch. It now extends the multistream API as well to 80/100/120 ms and incorporates changes based on Mark's comments.

Thanks to Greg and Michael for their advice. I have tried all these possibilities (and other); nothing seems to work; I persistently get the message: In open.connection(con, "r") : cannot open: HTTP status was '407 Proxy Authentication Required' It seems as if "proxy authentication required" is causing the problem. It seems I have to set up an .Renviron file, but I am

Could somebody please assist with the problem I have now. At our university certain changes have been made to users regarding accessing the internet. I have re-installed the (current) version of R, using custom settings (for Windows XP), choosing amongst other things "Internet2" somewhere. Now, when I wish to install new packages, I first have to select a CRAN mirror. R gives me a list

I have just installed the latest versions of R and Tinn-R (running Windows XP prof.) R 2.11.0 Tinn-R version 2.3.5.2 Everything seems fine, except for the following: I usually do this: Open Tinn-R and click on the R icon to open R - this splits the screen into two parts horiozontally, with Tinn-R on top and R in the bottom window. My problem is simply this: By highlighting one line, and click the
