RE: [R] dot density maps
Dear Roger, Thank you very much for the reply. And now I have to a apologize for my late response. I was quite a while out of the office. This is exactly what I was looking for. I think it will be of great help to have this implemented in a package.

I think that you can combine the polylist class from the maptools package with the csr function in the splancs package to position points randomly (the gridpts() finction can be used instead of csr() to give grid points): . . Could you indicate whether this function is any use, and if you would like it added to some suitable package?

[R] dot density maps
Dear All, In the moment i'm using the map and maptools package to read shapefiles and display the maps. I'm looking for the possibility to draw points (randomly positioned or positioned according to a grid) into the polygons instead of filling the polygons with colors. For example: a map (shapefile) with 10 countries, 15 points in the polygon of country A, 20 points in the polygon of country B.

[R] Greek fonts
Dear all, I need Greek text in titles, axis labels, etc. for graphs. The Graphs are produced in png-format - to use them later on in HTML pages. As the output has to be multilingual they are produced in a loop (for each language). The strings for the titles, labels ... are stored in a text file (Greek, English, French...). The only way I found so far - for Greek - is: 1) change the Rdevga by adding Courier to the fonts (the only font that worked for me). 2) Change the language for non-unicode programs in the windows setting to Greek Is there a way to avoid changing the setting for non-unicode programs in windows. If I'm changing the setting to Greek, non uni-code characters of other languages are not displayed correctly (ex. accents in French) Is there a way without changing the Rdevga in order to avoid manipulation after installation of R. Something like par(font=Courier : plain) I'm using R Version: 1.9 Windows: XP Thank you in advance for any help Johannes [[alternative HTML version deleted]] __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
[R] Rterm
Dear all, Two questions regarding rterm First: C:\Program Files\R\rw1081\bin\rterm.exe --vanilla test.r --args Arg1 Arg2 worked for me so far with r Version 1081, to start a R script with the given arguments. With R1090 C:\Program Files\R\rw1090\bin\rterm.exe --vanilla test.r --args Arg1 Arg2 There is the error message: Rterm.exe is not a valid Win32 application I tried on Windows 2000 and XP I couldn't find out what to change. Second: I would like to set the working directory as well, in the same command, when calling an r script with rterm.exe from the command line. Is there a way to do this? Can somebody help me with these issues?

What I usually do on Un*x-like systems is to cd to the directory first, then start the R run. Something like cd my favorite dir R --vanilla ... Since you're already specifying the absolute path for Rterm, the above should work... That's the only way. The `working directory' is the directory from which you launch an application (although you can fix that by a shortcut). R looks in the working directory for several things, e.g. a .Rprofile file, before it ever runs any R code like setwd. If that is not a problem you can use something like (from a decent shell) (echo setwd(somewhere); cat test.r) | Rterm.exe --args Arg1 to make the first R code run change directories. Or you can have at the top of test.r setwd(Sys.getenv(WD)) and use Rterm.exe WD=c:/data test.r --args Arg1 Arg2 -- Brian D.

[R] PNG Problem on Windows 98
Dear all, with the new version of R it is normally no problem to produce very fast graphics in the png format. In the office i want to work with R - Windows 98 is used. There are french versions and english versions of Windows 98 second edition. The png graphics are only on one computer correct. On the other computers - the x-axis labels, the legend text and the mtext (on the bottom) is missing. Attached are simple example files one in jpg (which is ok) and one in png format. produced with: png(test3.png); plot(1:100); mtext(c(aaa,bbb),c(1,2),c(4,1)); legend(50,50,); dev.off() for jpeg with jpeg(..) Any idea where the difference in the installation could be, like missing files ore necesarry updates for the windows system? Thank you very much in advance for any help.

Re: [R] Questions about png() on Windows
Thank you for the reply,
it is not essential that the format is png. Every format that can be
displayed in a web browser would be fine.
for an interactive web application i need to produce a lot of graphics
(up
to 50) on demand.
In the moment i'm using the png format.
The png()
...using png(file=Rplot%03d.png, ...); 'plots' ; dev.off()...
produces very good graphics. The problem is it takes too long to produce
the
png files.
The bitmap()
...using bitmap(file=Rplot%03d.png, type=type = png256,...);
'plots';
dev.off()...
works really fast. But on my system the quality is poor compared with
png()
even with a higher resolution than 72.
I'm using R 1.7.0 on Windows NT ; Ghostscript 8.00
1) Is there a possibility to speed up the png()
or to improve the quality of the png produced by bitmap()
There is a possibility. You have the source code, and we would be happy
for you to optimize it and submit a faster version. It looks up pixel
values one at a time, and the use of block operations should speed it up.
I don't think i have the ability (in the moment) to do so - but i will have
a try
Meanwhile: has somebody experience in improving the quality by setting
different parameters?
2) How is it possible to give names to the png files (if producing
more
than one plot) instead of Name+serial number like Rplot%03d.png
Just start a new device for each plot!
To open a new device every time slows it down again.
On my sytem:
system.time({
for(i in
1:50){xy-paste(i,.png,sep=);bitmap(xy);plot(rnorm(100));dev.off()}
})
[1] 4.40 5.62 42.70NANA
system.time({
bitmap(%03d.png);for(i in 1:50){plot(rnorm(100))};dev.off()
})
[1] 0.62 0.16 1.49 NA NA

[R] time series outbreak detection
Dear all, i have multivariate timeseries (weekly data). 1)Moving standard deviation With the filter function together with lag from package ts it is possible to calculate a moving average for the time series for each week at once (6 weeks back from the actual week and 12 weeks from the last two years). But i also need the associated standard deviations. Is there a function for this? 2)Robust Regression The time series derives from reported cases due to different pathogens. Some of them with saisonal pattern. There are huge differences in counts (depending on the pathogen) from zero up to several hundred counts per week. I have only data since 2001. I want to realize outbreak detection algorithms (so far, depending on the pathogen with Standard Deviation / Poisson and CUSUM). Beforehand i have to clean the data from past outbreaks. Has anybody experience with a rather robust regression model which cuts former outliers? Thank you very much for advice.

[R] rownames as parameter in functions
Dear all,
i want to give the names of columns of a data set (dat) as parameter to a
function,
in order to select single rows by the row names.
I tried several ways.
Like:
the data set :
dat
A B C D E
1 2 3 1 6
1 4 5 2 4
.. .. .. .. ..
the.col.names-c(A,C)
f-function(par){sapply,function(par)(dat$par*2)}
f(the.col.names)
Should give the result
A C
2 6
2 10
.. ..
Thank you in advance
