[R] Plot ticks and tick labels: thickness, colour?
I am displaying several series in one plot, and would like to make them distinct without having to employ a legend. I managed to color tickmarks, but have been unsuccessful with either one of a) making tickmarks thicker (without increasing the axis at the same time). From reading ?axis: lty, lwd: line type, width for the axis line and the tick marks. in would appear that I cannot obtain the one _without_ the other; or b) displaying the tick label in a different colour. Again, ?axis reads col: color for the axis line and the tick marks. [..] indicates that I can only set the tick mark, not the annotation. Any ideas or suggestions?

[R] Question about 'NA'
Hi all, Ive got a database with 10 columns (different variables) for 100 subjects, each column with different # of NA's. I'd like to know if it is possible to use a function to exclude the NA's using only a specific column, lets say: Data2 - omit.exclude(Data1$column1) ??, then Data3 - omit.exclude(Data1$column2) and so on I tried the code above but with no results Thanks for any help CM __ Yahoo!

Re: [R] gregmisc
In Carbon R 1.7.1 recommnded packages are already installed. VR itself is a bundle of package and not a package itself. MASS, rpart, spatial and nnet are already present in Carbon R.

If that is the complete list, then you are missing the VR bundle of packages, which includes MASS and is typically part of the 'recommended' package bundle, at least under Windows and Linux/Unix. I did a search of the Mac FAQ (**which appears to be for 1.6.0**), the R Admin manual and the r-help archive, since I do not have hands on experience with Macs. I may have to defer to other Mac OSX users for detailed guidance here. I also just checked Jan de Leeuw's web site at UCLA (http://gifi.stat.ucla.edu/pub/index.php) based upon a review of the README at http://cran.r-project.org/bin/macosx/ReadMe.txt. The indication is that the Mac port for V1.7.0 includes the base and recommended packages, however V1.7.1 is the base package set only, if my read is correct. If that is indeed the case, the solution to your problem may be as simple as using: install.packages(VR) being sure that you have appropriate R/W access permissions to the library directory tree on your system when you use that R command. If that solves the problem, then you should be ok and can load 'gregmisc' after VR is installed. I am copying both Jan de Leeuw and Stefano Iacus on this communication to be sure that I am offering appropriate advice here. Given the various time zones involved here, hopefully someone can expediently confirm the resolution to your problem. I hope this helps.

[R] probability plot correlation coefficient
As a newbie to R, I'm still rather at a loss for finding information (the commands names can be rather arcane)so I'm just posting my question: I would like to estimate the shape coefficient of diverse distributions (Weibull, gamma and Tukey-Lambda specifically, but other could be of interest) - Does R have a PPCC utility to estimate such parameter?(maximum value of correlation coef) - If yes how does one retrieve the numerical value from the graph? (see graphical example below) - The retrieval of numerical values is also a problem for me from the probability plots Thank for any help!

Re: [R] robust regression
Hi, the package is called quantreg and yes, it solved my problem. LAD regression was actually the method I was looking for, thanks a lot. However, some of my problems are rather large and even if I use the method 'fn' and 'pfn' recommended for large problems in 'rq' I get an error: res - rq(o ~ y + s -1,tau=0.5,method=fn,contrasts=list(s=(contr.sum))) Error: cannot allocate vector of size 1950212 Kb Is there are way to avoid that? The least square procedures are able to handle these large problems. best wishes, joerg Patrick Burns wrote: Two possible alternatives are: 1) Use least absolute deviation regression, which you can get from Roger Koenker's package that I think is called quantile. 2) The LAD regression is essentially equivalent to median polish (see, for instance, Understanding Robust and Exploratory Data Analysis by Hoaglin, Mosteller and Tukey). To gain some more efficiency for nearly Gaussian data, you could replace the median by a location estimator that is more efficient, such as a trimmed mean.

[R] L10N and i18n of R
Dear R-users of non-English speaking countires. Maybe a good news for those who want to use R in their local languages. Recently two Japanese, E. Nakama and M. Okada, succeeded in making R speak Japanese. At present, R can handle Japanese (as well as other languages, I guess) character strings if one use consoles which can understand Japanese. Also P. Murrell kindly provided a facility to plot hundreads of Japaense characaters as graphical symbols (Hershey vector fonts). Nakama and Okada's L10N (Localization) and i18n (internationalization) patches make it possible to use Japanese object names and to display Japanese characters on graphical devices (although still limited). If you are interested, please visit URL: http://www.okada.jp.org/RWiki/index.php?%5B%5Bi18n_of_R%5D%5D which is the only English page of RjpWiki, a Wiki-based collaboration site supported by Japanese R users. Nakama's patches can also handle other languages than Japanese. He kindly built Korean and Russian version of R (1.7.1) as rpm binaries (although he can understand neither Korean nor Russian). We are glad if these patches can give hints to R users who want to use local languages. Please note their patches are by no means complete and may potentially give your systems troubles. They and related binaries are offered without no warranty. Feedbacks and reports are welcome, but mere inquiries and complains not. Since the version up of R is so frequent, we cannot promise that these patches will be updated in future. Yours Shigeru Mase Dept. Math. and Comp.

The Carbon version needs precompiled binary packages (In principle you could compile them yourself, but that is not straightforward for this version). The precompiled binary packages live at http://cran.r-project.org/bin/macos/contrib/ As systemfit has no compiled code then I believe a binary package created on any system will work, so you could get a Windows zip file and unzip in in the library directory. Note that I have only tried this with a package created under Darwin. This system is clearly unsatisfactory, and that's why our Mac guru, Stefano Iacus, is now working on a GUI for the Darwin version rather than compiling packages.

[R] read.spss doesn't work anymore
A couple of months ago, probably using an older version of R, R used to run the following code just fine: library(foreign) data.exp1 - as.data.frame(read.spss(dataDef.sav)) Issuing the same commands now (after starting R using --vanilla), gives me the following behavior: library(foreign) x - read.spss(dataDef.sav) Error in read.spss(dataDef.sav) : Calloc could not allocate (-2147483648 of 1) memory x - read.spss(dataDef.sav) x - read.spss(dataDef.sav) Segmentation fault The first two assignments return instantaneously, after the second x contains all original SPSS variable/column names but no data, after the last read.spss - it takes a while before R returns with the Segmentation fault.
