Hi I have put up some web pages containing a number of plots (and diagrams) produced using R (they correspond to the figures for a book that I am working on about R graphics), with the relevant R code provided for each plot (or diagram), at http://www.stat.auckland.ac.nz/~paul/RGraphics/rgraphics.html Hope these are of some help/use; comments/suggestions welcome.

Thanks in advance. -- Ar...

Hi there, I hope to draw a plot like this: http://www.sg-chem.net/swizard/Ru-bqdi-spectra.gif is it possible to draw it using R? thanks for any suggestions. regards, Jinsong

Dear R users since R 2.6.0 when I try to save a graph from the Rgraphic device I find that the system becomes so slow that I'm forced to kill the process. This usually does not happen at the beginning of the session. The problem seems to arise when the system opens the dialog window to choose the directory and file name. (R version 2.6.1 under Windows XP) Thank you all Giovanni --

Hello, I would like to plot my data in a fashion similar to a boxplot, but plot the true data points without a box, just overlay lines of the summary generated by the boxplot. I have less than 10 observations within each group, so I think showing the actual data would be more effective than the box of the boxplot. I have been unable to find a way to do this. Here is example data: >

Hello ! There is something quite simple I want to do with R but I found nowhere in the help how to do it. I just want to plot data which are in a matrix, every column being a data set and having the same x-axis (just an index). So for example if I have a 50 x 6 matrix I want 6 set of points on the same plot. I tried plot,new() plot(MATRIX[,1]) plot(MATRIX[,2]) ... but it replaces the previous

Dear R users, I want to create a C program drawing a scatter plot with R functions. Is it possible to do such a thing with interfaces declared in 'Rgraphics.h'? If so, I would like to get sample C sources. >From a user in Japan.

...g for. As far as I understand, layout() is intended to flexibly divide the plot region, not to subdivide the plot region nor the figure region. One solution could be to export PLOT 1 , say as png, and then overlay on it PLOT 2 with pixmap() as in this example http://www.stat.auckland.ac.nz/~paul/RGraphics/custombase-pixmap.R but it seems to me a bit too much complicate Thanks in advance for your time -- Ottorino-Luca Pantani, Universit? di Firenze Dip.

Hi again! I put this question in another topics post before but I fear it might drown there. Is it possible to have transparent / alpha blended colors for pie charts? I am using the pies in a map of pies and those pies are sometimes overlapping so it would be great to see if another pie lies beneath. Thanks, Werner

Hi folks, I try to plot a variable which contains string-variables. it works, but the problem is that there are a lot of values at the x axis (up to 24) SO i have to scale or rotate the label at the x axis. I tried this with the text() function. It doesn't work correctly. Is there a simple way to rotate the labels? Best regards, Sebastian

...ortable asking questions about the design of new a new grid class in R-help where I'm guessing most people won't be interested. Of course having yet another mailing list would only make sense if it's to be followed by those people who work with Grid (lattice, vcd, ggplot2, latticeExtra, Rgraphics, etc.). Having read a bit of code from these packages recently, I get the feeling that several people may have been facing similar problems or reinventing the same things. Just a thought, Best regards, baptiste *: http://www.r-project.org/mail.html

Dear r-list, I am trying to visually seperate the two main clusters of a dendrogram. The idea is to use: 'edgePar=list(lty=3)' for 'dend1[[1]]' and 'edgePar=list(lty=1)' for 'dend1[[2]]' I have not found a way to solve this. Any suggestions? Patrick hc <- hclust(dist(USArrests), "ave") (dend1 <- as.dendrogram(hc)) par(mfrow=c(2,2)) plot(dend1)

...ug? And equally important, does anybody know how I could get this type of plot in an easy way? Thank you very much, Vera PS: in case it is not clear what I mean with "plotting region", please check page 6 of the following document http://www.stat.auckland.ac.nz/~paul/Talks/Rgraphics.pdf [[alternative HTML version deleted]]

Hi: I am doing some work that involves plotting points of interest superimposed on photographs and maps. I can produce the plots fine in R, but so far I have had to do the superimposition externally, which makes it tedious to do exploratory work. I have looked to see if there is some capability to put a background picture on a plot window, but I have not found anything. Advice, anyone? Cheers

hello, the example below does not work. (i know it's not supposed, but it makes it clear what i'm trying to achieve) par(mfrow=c(2,1)) xyplot(y~x2|x1,data=dataframe1,pch=20) xyplot(y~x2|x1,data=dataframe2,pch=20) i know i could probably merge the two datasets and do something like xyplot(y~x2|x1+dataset,data=merged) any other suggestion? thanks.

...lower left corner. In some ways the figure I'm trying to create is analogous to figure 1.5 in Paul Murrell's excellent "R Graphics", which combines a map of New Zealand with a map of the world. I tried adapting the code for that figure, http://www.stat.auckland.ac.nz/~paul/RGraphics/examples-map.R However, the following problem has me stumped: New Zealand lies along a N.E. - S.W. axis, leaving room in the bottom right (or top left) corner of a figure for a small map of the world. In contrast the 48 contiguous states nearly fill a rectangular figure, leaving no room for...

...ctures RUtilities.h Functions which operate at the C level without special knowlege of R structures (But maybe not Math). RMath.h We probably need a separate set of declarations but maybe not. RGraphics.h This is big and is logically separate from other C code. Some things which are not in here should be -- e.g. hsv2rgb.
