Fonts and Line widths
Hi All R guru's, A couple of simple questions which I cannot find answers to in "an introduction to R" or in the reference manuals. I am running R on Win95, and have plotted up quite a nice box and whisker plot: char<-read.table("n:/reddinm/grifpr~1/survey/char.txt") attach(char) boxplot(Al,Fe,OC,pH, range=0,xaxis=FALSE, ylab="Proportion of Unirigated

Sans Serif Fonts?
Hi All, I am preparing a few plots for publication. Unfortunately the journal requires figures to have all text in a sans serif fonts. I realise that there is support for the use of Hershey vector fonts in the function TEXT, but how do I get the text on axes to be sans serif? For example, the labels and axis values produced from this line of code: plot(SolPC, SorbPC, ylab="Sorbed P

Repeated Measures?
HI There, I was wondering if there was a procedure in R for carrying out greenhhouse geiser type repeated measures analysis and ante-dependence testing? I've checked out the nicely written manuals, but it seems to lack an entry in the index (maybe because this technique has not been implemented yet).

Repeated Measures
Hi R Gurus, I am more or less a beginner with R. I have searched your FAQ, manuals, and the archives of this list for an answer to this question, unsuccessfully. I commonly do analysis of chemical characteristics of soils, by depth intervals (e.g. 0-100 mm, 100-200, 200-300, etc), comparing two soil profiles that have received some treatment (effluent). In Genstat I can handle this problem

matching a sequence in a vector?
Hi All, I've been trawling through the documentation and listserv archives on this topic -- but as yet have not found a solution. I'm sure this is pretty simple with R, but I cannot work out how without resorting to ugly nested loops. As far as I can tell, grep, match, and %in% are not the correct tools. Question: given these vectors -- patrn <- c(1,2,3,4) exmpl <-

Redirecting Output to Clipboard
Hi R Gurus, I have a question that some of you may have dealt with before. I would redirect output to the clipboard, rather than to the screen. Is this possible? Is a function already written for it, or is it just an option in print? Any help would be appreciated. Also, thanks to all those who have helped develop this great software, or who make the effort here to support the user-base.

Par arguments and pin and fin
Hi R Gurus, I want to change the size and shape of the plot region, but cannot work out how to use the arguments pin and fin in the par() function e.g. : par(lwd=1.5, font=1, mfrow=c(2,1), pty="m", plt=c(.1,.9, 0.1,.9), mar=c(1,4,0.1,0.1) pin=c(6,12)) this gives me a syntax error associated with pin. How should I be using these arguments? Thanks, Matt Redding

Grouped Regression
HI All R Gurus, Please reply directly to this email if you have a suggestion, as I am not currently an R-help member. I would like to complete a non-linear regression with groups. Having gone down the path of completing such things under GENSTAT, I would prefer to do it with R. My example data set is... TimeTreat ExtrVol2 SorbedT ET1 39.5 384.5 ET1

Bootstrapping on R
Does R have a bootstrap command like SPlus, or do we have to form our own code if we want to do bootstrapping in R?

does a factorial function exist
I've looked through the documentation with R-0.64.1 and have been unable to find a high-level function for evaluation of factorials (i.e., n!, not factorial designs). Is there such a function? It is trivial to code, so everyone could write their own, but it also would be worthwhile as a standard tool. I'm guessing I am just overlooking it.

R installation problems...
Dear all I already posted this problem to r-help in mid-decembre; see http://www.r-project.org/nocvs/mail/r-help/2000/3876.html But, up to now it did not manage to get R properly working. I reinstalled R-1.0.0, R-1.1.1 and R-1.2.0 from scratch, and always run into the same error message: ... [Previously saved workspace restored] now

Letter Spacing
Hi All, I've been trying to make some adjustments to the graphics in a paper I wrote some time ago, for which the comments have been returned from the reviewers. I always use R for publication graphics...I think it does the best job available, for the things I am interested in. I could not get my graphics in R 181 to look the same as the old ones (completed 8 months ago), the text seemed

nls: singular convergeance
Dear R-experts, I have 28 data points that I would like to fit with a non linear broken-stick -- with three fitted parameters. When I view trace -- and use the final values as lines on the graph of data -- it looks pretty good. Q1. Why am I getting singular convergeance? Q2. Can you suggest another approach that may prove more satisfying? I have read previous examples on nls and this sort of

rpart unbalanced data
Hello all, I am currently working with rpart to classify vegetation types by spectral characteristics, and am comming up with poor classifications based on the fact that I have some vegetation types that have only 15 observations, while others have over 100. I have attempted to supply prior weights to the dataset, though this does not improve the classification greatly. Could anyone supply some
