For some reason, off-line help seems no longer to be working in R for me. I.e. if I do, e.g., > help(plot,offline=T) ***nothing*** happens. Previously, (before I re-installed R to get command-line editing working, I think) if did this, a file called ``plot.ps'' was created in the current working directory, and I could happily lpr this file. Now .... nadda. I have a ***vague***

Dear gentleman, i am deploying and unix/windows network and samba has been doing a great job since so far. But now, i am in need to set my network printers to be able to receive jobs from any machine in the network. Some time ago, i reached an internet site related to printer in unix environment. It was very useful since there was detailed information for hundreds of printer device capabilities

Just now I again had occasion to want nested describe lists in a documentation file. I found that the bug which I reported on 18 October, 2001 still persists. I checked on the bug report at the R web page, and found that the notes say ``Not a problem in R 1.4.0 (2001-12-08)''. Well, it's still a problem for me --- using R 1.4.1. (Details: platform sparc-sun-solaris2.7 arch

I've looked through the FAQ and can't find anything about this. I'm working on a Sun machine, running Solaris 2.7. I'm a new R-user; have been using Splus for millenia, and finally decided it was time I got going with R. So I downloaded R, installed it, fiddled about a bit, and found that command-line editing was absent. Scrounging through the documentation some more, I saw it

My google search for Plackett's Algorithm didn't return too much except that Plackett's algorithm appears to be useful in Control Theory - it is elaborated as "Plackett's algorithm for on-line recursive least squares estimation". Sounds something like what I want. I am looking at developing a user modelling type app (new data points coming in and wanting to dynamically

Thanks to Rolph Turner and Jason Turner ... I guess I was too excited about getting back on the list after an absense of several years ... I'll be a little more thoughtful about the problem before posting next time, and a little less trigger-happy with the "Send" e-mail button. Never-the-less, much appreciated. - Mohamed -----Original Message----- From: Rolf Turner

I gather from reading the back-issues of r-help that it should be possible (modulo a number of caveats) to read an excel (yuck!) file into R using RODBC. I have obtained and installed ODBC and the RODBC package, but cannot for the life of me figure out how to go about it. Can anyone give me a simple recipe? I have an excel file on cdrom, say: /mnt/cdrom/melvin.xls I have started R and loaded

This posting has nothing to do with R (except maybe that I am using R very heavily in writing the paper to which the question pertains.) I simply wish to draw upon the impressive knowledge and wisdom of the R community. Since this question is way off topic, if anybody has the urge to reply, they should probably email me directly: rolf at math.unb.ca rather than via this list. My question

This question has little or nothing to do with R; as usual I'm simply hoping to take advantage of the great depth of knowledge and expertise in the R community. Anyone who is interested in replying should send email directly to me (rolf at math.unb.ca) and not to this list.

He said: ``I have a 992 x 74 matrix. I would like to form a new matrix by averaging each 4 rows from the original one.'' I.e. he wants (I think) the first row of the new matrix to be the

I mis-spoke. It seems I had two collections of functions in the same directory. One by Colin Goodall, and one by David Scott (I have no record of where he is/was located). It is the *latter* collection that does all its work from within Fortran. I'll have another look at what Colin Goodall actually wrote to see if it could be useful to guarav. cheers, Rolf Turner rolf at

If one specifies new options in a package, using the options() function, where does/should one document these new options? E.g. suppose that I put the line options(melvin=42) in a file zzz.R in the R directory of the package source, where the package contains functions foo(), bar(), clyde(), and irving() which all query options("melvin") and take some action based on the value of

I just tried to install R version 1.5.1, and it is failing ``make check'', as follows: $ make check `Makedeps' is up to date. running code in 'base-Ex.R' ...*** Error code 1 make: Fatal error: Command failed for target `base-Ex.Rout' Current working directory /home1/faculty/rolf/Traal/Rtmp/R-1.5.1/tests/Examples *** Error code 1 make: Fatal error: Command failed for target

Our computing services people have recently reconfigured the Sun compilers structure on our network, and I can no longer install, on our Sun/Solaris machine, a certain package (spatstat) with which I am heavily involved. (The same problem may well pertain to other packages as well; I haven't yet experimented except with spatstat.) Strictly speaking I can ***install*** it, but when I try to

I have just installed R version 2.14.0 and tried to re-build and re-check some of the packages that I maintain.

Dear friends, Over the past weeks, I have been asking a lot of questions about how to use R in Bayesian analysis. I am brand new to R, but I am very pleased with it. I started with winbugs but I found winbugs to be a limited software, not bad but has several limitations. By contrast, R allows the analyst to tackle any problem with a huge set of tools for any kind of analysis. I love R. In

In checking over the solutions to some homework that I had assigned I observed the fact that in R (version 2.4.0) pnorm(-1.46) gives 0.07214504. The tables in the text book that I am using for the course give the probability as 0.0722. Fascinated, I scanned through 5 or 6 other text books (amongst the dozens of freebies from publishers that lurk on my shelf) and found that some agree with R

Yesterday I downloaded R-2.2.0.tar.gz, gunzipped and untarred, and did the usual ./configure and make. Everything seemed to go smoothly until it got to the bit about installing recommended packages. It got past ``spatial'' but turned up a fatal error in respect of the ``boot'' package. Here is some of what appeared on the screen:

I've just installed version 1.4.0 of R, and am experiencing a puzzling phenomenon with the library() function.
