Dear R users, I want to share my joy with you. Please see the following excellent introduction to R "Statistiques avec R " by Vincent Zoonekynd http://zoonek2.free.fr/UNIX/48_R/all.html In paticular, you can see a lot of fascinating graphics examples of R from which you can get many hints. Soryy if this is already well-known, but the CRAN search did not show nothing with the keyword

Hello, I am running R under Linux/x11. I would like to call R from a shell script and have it display a series of graphics. The graphics should remain visible until the user clicks or presses a key. I first tried R BATCH, but it does not load the x11 module, making it impossible to open x11 or png devices. Then, I tried to call R with a 'here' script: R --vanilla --quiet --args

Hello, I use the function 'aggregate' a lot. One small annoyance is that it is necessary to name the factors in the 'by' list to get the names in the resulting data.frame (else, they appear as Group.1, Group.2...etc). For example, I am forced to write: aggregate(y,list(f1=f1,f2=f2),mean) instead of aggregate(y,list(f1,f2),mean) (for two factors with short names, it is not such

Hi, I read the 2000 thread on a MetaPost device in R. If I understand correctly, the main problem with the concept is that R wants the device driver to give back information on the size of strings/labels. To the bet of my knowledge, MetaPost _does_ make it possible to measure the bounding box of text (see section 7.3: Measuring text in the MetaPost manual). For example, one could get the size of

Hi, I know the R can make eps output. But metapost sees to be an even better choice for me. I've been using gnuplot for a while, it seems it has excellent support with its metapost latex terminal. So I can insert any latex equation in the figure. Meanwhile, I can make the font in the figure will be consistent with font used in the main text. I searched R help, but I can not find metapost

Hello Coming from matlab background, I could use some help on this one. I need to generate a data set based on this equation X(t) = 3.8x(t-1) (1-x(t-1)) + e(t), where e(t) is a N(0,0,001) random variable I need say 100 values. How do I do this? Thanks

Hi All, I've started work on a MetaPost device driver (please don't hold your breath). I've copied the XFig driver and renamed everything and this works, I can open the new metapost() and it works exactly like the xfig driver. Now all I have to do is the actual work! Just one question. There is a magic number in ExtEntries as follows: static const R_ExternalMethodDef ExtEntries[] =

Hi all, By default, MetaPost passes all text through TeX. This has the advantage of allowing essentially any TeX symbols in titles and labels. It give us, who use the multibyte character in ordinary communication, much convenience. Gnuplot has fulfilled this function, and it give me a deep impression for I could use Chinese character in plots with a minor modification to the MetaPost file. I

Dear All, I am doing some exercise in statistics textbook on comparison of two experimental means. Is it possible to use t.test() do t-test when I have only two means, sample size, two standard deviations ? (no raw data). Thanks. Pramote

Hi, 1. I started work on a metapost graphics driver a week or so ago and it is gradually taking shape. I'm building up my own test cases into a script as I go, but figured you may have a "canonical testing script" of cases a driver must handle? 2. The clipping function looks like being a tricky problem. It seems to me that the callers of the driver assume that clipping affects all

Hi all, To develop the metapost driver, I did an svn checkout (R-2-4-branch revision 40647) as instructed in http://developer.r-project.org/SVNtips.html i.e., I did a, svn co $REPOS/branches/R-2-4-branch r-release-branch/R Not being a core developer, can I just commit the changes? Am I on the right branch? Most of the work is in devPS.c, but there are also some documentation changes

Dears friends, I have been translating and extended, with educational porposes only, the available material in the www (http://zoonek2.free.fr/UNIX/48_R/all.html) "Statistcs avec R" for the Portuguese of Brazil. I consider the material very good and would like to share this work with anothers users R. Already I translated and I extended two chapters: Introduction to the R and analysis

I would like to know if a MetaPost device is available or in the plans. A search MetaPost in the documents and list archives did not turn up anything. [I would prefer to use MetaPost when the graphics is to be included in a document that I want in both hard-copy and in pdf formats.] If not, how easy/hard is it to add a new device to R? I caouln't see anything about adding devices in the

Hello, I routinely use aov and and the Error term to perform analyses of variance of experiments with 'within-subject' factors. I wonder whether a notion like 'multistratum models' exists for glm models when performing a logit analysis (without being 100% sure whether this would make sense). I have data of an experiment where the outcome is a categorical variable: 20

Dear all, I'm writing a small program to read a file that receives data every time (e.g. every 1second ). During the execution of my program I get the message: " Error in read.table("file.txt", header = T, sep = ";") : no lines available in input " I suppose that it happens when I try to read the "file.txt" while it is being written. To overcome

This relates to a message from Christophe Pallier to r-help some time ago. Like myself, he finds aggregate very useful, but the interface a little cumbersome. I've implemented a more compact formula interface, found at the bottom of this message: data(ToothGrowth) # I used to aggregate like this: aggregate(list(len=ToothGrowth$len),

Hello, this is a follow up on my previous inquiry regarding the use of the map library (Becker and Wilks 1993). Using the 'world' database I would like to draw filled countries in a world map so that the filling colors of each country corresponds to the value of a policy variable "fix.float" at a specific "year" (the goal is to visualize a policy diffusion pattern

The following code was adapted from an example Vincent Zoonekynd gave on his web site http://zoonek2.free.fr/UNIX/48_R/03.html: n <- 1000 x <- rnorm(n) qqnorm(x) qqline(x, col="red") op <- par(fig=c(.02,.5,.5,.98), new=TRUE) hist(x, probability=T, col="light blue", xlab="", ylab="", main="", axes=F) lines(density(x),
