I am trying to draw a figure using GRASP, and I get the following error message in R: Error in image.default(map, col = heat.colors(12)) : invalid z limits What are z limits? Can I manually set them? Please let me know if you have any insight on this! Thanks, Jennifer Skene I believe that the z limits in GRASP relate to the third dimensional variable. If you are using spatial data that uses either altitude or another variable that gives a pseudo-surface, you should probably check the variable's range.

You can use the search option to filter for packages that have fonts in their descritpion. Install any that aren't. SuSE seems to be a little funny about the X-11 fonts. Peter Dalgaard just let me know about that a short time ago.

Re: [R] A rude question
On Wednesday 26 January 2005 21:09, [EMAIL PROTECTED] wrote: Dear all, I am beginner using R. I have a question about it. When you use it, since it is written by so many authors, how do you know that the results are trustable?(I don't want to affend anyone, also I trust people). But I think this should be a question. Almost all software - generally all important software - is has numerous authors. Windows has hundreds, perhaps thousand of coders. So too does Unix. The big difference between open source and closed source is not in the number of authors. Rather it is in the open availability of the code. Arguably, if there is sufficient interest in an open source project, studies have indicated that the code is likely to be superior to that of a comparable closed source program. This a probability though, not a natural law. If you are concerned about the trustworthiness of R, then perhaps the best gauge is that some of our favorite if occasionally curmudgeonly authors on this list are also experts in S and S-Plus, the proprietary, closed source language of which R is also a dialect. They evidently know what they're doing and work comfortably in both domains. If you compare statistical results using R and Excel, there is no question that R is superior, but that will also be true if you tested Excel against S-Plus, or SAS, or NCSS - all proprietary programs, or any number of other closed and open source programs designed to do statistical analyses. At the same time just about any spreadsheet, open or closed source will also suffer in a similar comparison. If you want a more information about the safety of Excel I would suggest this site: http://www.burns-stat.com/pages/Tutor/spreadsheet_addiction.html Read the various links. Beyond this there is a broad literature available on the risks and benefits of open and close source programs. Read it.

Re: Fw: [R] R Citation
On Friday 21 January 2005 14:48, Steve McIntyre wrote: Dear Achim, Thanks for the comment. Here is the publisher's style guideline (AGU) Because the Internet is dynamic environment and sites may change or move, treat World Wide Web, ftp files, and electronically archived data stored at data centers other than World or National Data Centers as unpublished, i.e., in text only. http://www.agu.org/pubs/AuthorRefSheet.pdf So by this policy, R and its packages cannot be included in the list of references and has the same citation as a pers.comm. The problem for my paper can be resolved by removing the citation from references to text, but this seems unfair to R and the package authors for AGU publications. AGU does recognize some permanent data archives listed here http://www.agu.org/pubs/datacent.html - maybe it would make sense to have a mirror at one of these permanent archives for packages and versions. Regards, Steve McIntyre Steve, Depending upon the actual format of your paper, you might either add a reference to R in your Methods or in an acknowledgements section if the format permits such. Looking at the AGU publishing guide, their obvious concern is to insure that the data used in an article are sourced properly. Statistical software, like ground-penetrating radar or a magnetometer for instance, is a tool. Thus it really falls within the scope of methods. It is reasonable in that case to cite the URL in the text. You can also elaborate somewhat and explain sonething of the history and origins of R, citing the The R Reference Manual by the R Development Core Team, which is available through Amazon Books (volume 1 for mere $57.56 plus shipping at present). You ought to be able with a bit of creativity to drag in mention of both the URL and the manuals.

[R] pair() and X11 fonts error
I am encountering an font error when using either plot() or pairs() for a scatter plot matrice under some circumstances. For instances pairs(hills) using the hills data set in MASS results in the following error: Error in text.default(x, y, txt, cex = cex, font = font) : X11 font at size 16 could not be loaded However pairs(iris) works fine. Since the iris data set contains considerably more variables than hills, I am at sea regarding the correction.

Re: [R] Font problem
Thank you for the help. The problem was, as Peter and Marc suggested, that the 100 dpi fonts were missing. Installing them made the difference. John __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
[R] Font problem
Some plots fail due to a problem with the X11 fonts. I get a message that X11 font at size 22 could not be loaded. The demo() graphics routine for instance dies during the third chart. The graphics demo calls font.main=1 and that seems to be where the error is. I believe this is due to a configuration problem on my system, however I can't find where in the environment font.main looks for the font to use. I am running SuSE 9.0 and use the KDE desktop. However, I have also replicated this in GNOME and WindowMaker. Varying the fonts used by the console does notb effect the result.

Re: [R] R 1.8.1 on SUSE 9.0
I have 1.8.1 running on SuSE 9.0 as I write. I use the Professional release, which comes with most development packages, certainly all the ones needed to compile R-1.8.1. If you do not have the Professional version, you will have to acquire the full collection. You can use YaST to check what is available. Bring up the YaST window and highlight Software, then in the right hand window Install and Remove Software. When the window comes up, click on the filter box and use the search facility. I would point out though that I have R-1.8.1 running as I write and YaST search tells me that the librbary you listed is not present on my system either. What OS are you running?

[R] Compiling R
I have a generally successful compiled R 1.8.0 version installed on a SuSE 9.0 system. One frustration however is that the basic keyboard functions of BASH have not completely carried through and the up, down, left and right arrow keys don't behave as they do on the regular shell command line. That is no command history can be accessed and the cursor cannot be back-spaced over a recalled command to edit it. I expect that I am missing a --with- statment but I am not certain what it should be. Is there any help file that details the fine points for compiling R? INSTALL does not contain the information I am interested in. Thank you, jwdougherty __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
