Hello, R users. In C (or C++) language, a function can be used as an argument of another function as follows: // function used as an argument void foo(int x) { ... } // function using a function as an argument void bar(void (*func)(int ), int arg1, int arg2) { .... } // The function 'bar' will be called as follows int main() { .... bar(foo, arg4foo, other_arg);

Hi, R-users. I tried to install the 'RODBC' package by input C:\R>RCMD install RODBC_0_8-2_tar.tar , but I got the message 'Error: cannot change to directory 'RODBC_0_8-2_tar.tar' ' and failed to install. The file 'tar32.dll' lies in the system directory. How can I install the package above mentioned? OS:Win95 R_HOME:c:\R\rw1020 >From Kobe,

Hi, all. Now I am trying to embed R in C++ code with COM interface. Which header file should be included (specially in case of using Borland C++ compiler)? And are there any library files to be linked when compiling?

OS : Win95 R Version : 1.4.0 JDK Version : 1.3.0 Hi, R-statisticians all over the world. I'm trying to handling R objects in the Java code as follows: [c:\myjava\R2JTest.java] import org.omegahat.R.Java.*; class R2JTest { public static void main(String args[]) { REvaluator e = new REvaluator(); Object val = e.eval("objects()"); int i;

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

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

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.

Hello all I would like to visualize the hazard ratios of a cox proportional hazards model. I have seen some good examples in the New England Journal of Medicine: http://content.nejm.org/cgi/content/short/353/26/2747/F3 http://content.nejm.org/cgi/content/short/350/26/2654/F2 (I hope these are open access, but I am not sure) And something similar in the book 'R Graphics' by Paul

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

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)

Dear R-users, after seeking for help in R-search I did not find any hint on my particular problem. Countless help on "true" overlay, but nothing on this. Please consider the following: par(mfrow = c(2, 1)) T <- seq(0, 20, by = 0.01) ## PLOT 1 plot(T, 30*exp(-0.65*T), type = "l" ) points(T, 30*exp(-0.26 * T), type = "l", lty = "F8") points(T,

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.

Hi, I need to draw a line segment between two points on different plots in the same multigraph.I've tried looking at the zoominplot function in plotrix but havent understood much.any help is appreciated ~Aks [[alternative HTML version deleted]]

Dear all, Would it make sense to have a separate mailing list (special interest group*) for Grid graphics? (or is there one already?) I don't feel comfortable 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

Dear R users, Following some of the recent questions and discussions about the R plotting abilities, it occurred to me again that it would be very valuable to have an R graph gallery. Eric Lecoutre made a very nice example in: http://www.stat.ucl.ac.be/ISpersonnel/lecoutre/stats/fichiers/_gallery.pdf It would be very useful to many beginners, but probably also advanced users of R, to have an

Hello, My name is Philippe Favrot, I'm a french occupational doctor (working in Luxembourg), and I'm an "R beginner". I would be happy you could help me about the utilization of "R". Recently, I measured sound levels in a plant. Before the measuring, I divided the plant in 3 virtual rows and 8 virtual columns. I measured the sound level at each intersection of rows

I am trying to create some graphs with R and it seems to be able to do what I need. However, I have so far not been able to find any sort of explanation of how the graphics system works. I am for instance trying to create a multiple figure, and I seem to have to call plot.new() before every new plot command, I have however not found any explanation of what this actually does. ?plot.new does give
