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:

[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 -

[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)

Re: [R] 3D matrix

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 -

[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

help.search(subset) on my R installation gives: nchoosek(vsn)List all subsets of size k from n objects and vsn is one of the Bioconductor packages. From that, the index.subsets() you want shouldn't be too hard to construct... HTH, Andy -Original Message- From: Spencer

[R] high memory allocation

Hello, I have trouble with my cluster analysis using package cluster. diana and agnes both seem to try to allocate memory directly, so I can not use virtual memory of my Windows2000 operation system. I do have 320 MB of memory. But they claim about 600 MB. Do I have a chance to do the analysis
