plot(pam.object) error with R-1.7.0 on Red-Hat 8.0 i686
I don't know if there is some fault in compiling or a bug of the new R-1.7.0 version: cl.pam.2 <- pam(as.dist(1-cor(mel.data)),2) plot(cl.pam.2) perform a right partitioning and silhouette plot on the old R-1.6.2 instead "Error in clusplot.default(x$diss,...... ; x is not numeric" is the output on the new R-1.7.0. Same platform: RH8.0 i686. Some suggestions? A.S.

expressions and paste
I have written a function to plot data which will be used for various different chemistries. A simplified version is: plot_data <- function(risk,levels,chem,sd2,measure){ plot(risk, levels,main=paste ("per", sd2, measure, "\n in usual", chem)) } The problem is with the title. This works fine if the variable "chem" is just text, but if it is an expression then

normality test
Hello, I am analysing several samples whose sizes are from 9 to 110. I would like to test their distribution with R, whether they are normal or not. I wonder which test for normality from R should I use . Thank you for help.

which on array
Good morning ! Today I found a strange, for my poor knowledge of R, behaviour of 'which' on a matrix: HAL9000> str(cluster.matrix) num [1:227, 1:6300] 2 2 2 2 2 2 2 2 2 2 ... HAL9000> class(cluster.matrix) [1] "matrix" HAL9000> ase <- cluster.matrix[1:5,1:5] HAL9000> ase [,1] [,2] [,3] [,4] [,5] [1,] 2 2 2 0 -2 [2,] 2 2 2 0 -2 [3,]

lines on class objects table
Hi dear R-list. I would superimpose many lines of class 'table' over a plot(table.0,type ="l",...), I tried 'lines(table.n,type="l",..)' but its behaviour is quite different from those of 'plot' : >plot(table,type="l"...) # start graph from x = 0 >lines(table,type="l"...) # start graph from x = 1 Some sugestions? Thanks

Graph window is not available any more
Hi all, I have currently been using the book Modern Applied Statistics with S from Venables and Ripley. At chapter 6 on Linear Statistical models I wanted to produce the plot as shown by "Figure 6.1" using Whiteside's data. xyplot command seems not to work on my version of "R"(version 1.7.0) running on different environments (Win XP, Win 98 and Win 2000). I then used the

Number Format
Hi A very simple question on number formats. After some calculations, some variables I have come out looking like this: -1.892972e+00 Now apart from the fact that the "e+00" is completely redundant, I would rather have the number represented without the e bit. I want to export data like this to a text file and would rather have: -1.892972 than -1.892972e+00 I have tried

Rweb: how to use source()
I cannot discover how to set or find the working directory in Rweb, so that I can source() a file from the server. The file I source() must refer to a data file in its directory. setwd() does not do anything, and getwd() says that the working directory is in /var/www/cgi-bin/ (on Linux).

place 4 ini files
Dear expeRts, I collect some lab specific functions for a package. Some of this functions need initial data (ini files written in R-code). My question is: Where is the place in the package structure for such files; how to load the files? I think something like: source(paste(R.home(),"/library/__pkg__/data/__.ini.R", sep="")) looks a bit clumsy. I haven't find something

small world models?
Hi, I've searched the archives for a discussion on the use of R for developing "small world" or "scale-free" network models but have been unable to dig anything up. Is anyone working on these types of models using R, and if so, have you found this language amenable to their development? thanks, matt farnsworth

gene ontology association
Hello! I don't know if there is some R-package able to associate ontology to a long list of GeneBank Name (a txt-tab file or an XML file), i.e. I would as output a formatted file with 4 columns (1:GeneBank Name 2,3,4:ontology). I know that I have to perform a mapping of genes, I got a look on AnnBuilder pkg, but I 've not idea from where to start. Some suggestion? Thanks in advance!

I have to build many matrix, with different dimensions, and I would to assign them a same 'prefix' name, i.e. "aval", but, obviuosly different suffix, something like: for (i in 1:n) { aval%i% <- matrix(scan(data....),nrow=nr[i],ncol=nc[i] ... } where "%i%"
