Hello useRs and helpRs, Some time ago, in a gallaxy far away (here is the thread : http://finzi.psych.upenn.edu/R/Rhelp02a/archive/46532.html ) we discussed about a graph gallery showing the power of R in that domain. I did some work around that, and there is a (pretty advanced) draft here : http://addictedtor.free.fr/graphiques/displayGallery.php For instance, there are some of my graphs,

Dear All, is there a simple way to print a data.frame without its row.names? example: datum <- as.Date(c("2004-01-01", "2004-01-06", "2004-04-12")) content <- c('Neujahr', 'Hl 3 K.', 'Ostern') df1 <- data.frame(datum, content) print(df1) datum content 1 2004-01-01 Neujahr 2 2004-01-06 Hl 3 K. 3 2004-04-12 Ostern Can I get

I'm working on some heatmaps, and the person I'm working with would prefer a red-black-green color palette (red denoting gene induction and green denoting gene repression). Does such a palette exist already? If not, is there an easy way to create one? Thanks, Jake

Good morning, (sorry for my english) i have some problems to put off by extimation ARIMA coefficients the ones not significatives. Exist a method to extimate only that significatives? i use the command: arima(). thanks to all Stefano [[alternative HTML version deleted]]

Hi, I have a grouping of some observations. I want to cluster them using hierarchical clustering and compare how the hierarchical clustering shows up vis-a-vis the groupings. Is it possible to do this in color? I guess what I am looking for is a way to color the labels of a hierarchical clustering plot using different colors according to the original grouping. Any suggestions? Many thanks and

Hi Everyone, I'm trying to use cutree to get the clusters after hclust. What I used is: mycluster<-cutree(cnclust,h=0.5) Now, my problem is, how can I get the actual clusters? Thanks! Best, Baoqiang Cao

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

Hello, I am looking for documentation (PDF ?) about doing clustering with the EM Algorithm on R... I'm sorry for this question which may be trivial... Thanks... Dominique

hi, is it possible to create a matrix with one row and according to add a row? in fact, at present, I'm doing an algorithm which fill a matrix. On the web site of CRAN, the package basic is impossible to be load! can you tell me where i can found it! Thanks Sabine --------------------------------- [[alternative HTML version deleted]]

Hello, On my barplot, I have on the axis y, the names of the rows of my matrix r_mat! is it possible to change the color of these names on my barplot? barplot2(t(r_mat),beside=TRUE,horiz=TRUE,plot.grid=TRUE,xlab="R",font.lab=4,las=2,xlim=c(0,1)) thanks, Sabine --------------------------------- [[alternative HTML version deleted]]

Hi all, I want to draw a line with the values of x marked in X axis. I tried with x <- c(0,6,12,18,24,30) #coordinates of points x y <- c(2,5,7,5,7,16) #coordinates of points y plot(x,type="n",xlab="Months",ylab="Y values",main="main",ylim=c(0,16),xlim=c(0,30)) lines(x,y) The graph shows by default an increment of the sequence in x axis that

hi all, I wish to draw on the same graphic device 3 functions. But i don't want them to be on different graph, i want to compare them on the same I don't need mfrow or mfcol, I need something else... 1 graph on 1 device inside this graph 3 ploted function. I saw something unsing data.frame, but i think it's overkill, and something less complicated must exist, if not why? why not

That's probably a stupid question, but I'm looking for a low-level command which plots ellipse, specifying only center and deformation axes. The purpose is to illustrate bivariates gaussians with 2D .95 confident levels without using any specific library. Thanxs for your help, Guillaume

Dear List, I am using R to learn bootstrapping concepts. Not to be oblivious to the contributed packages of boot and bootstrap, I have opted to do the following as a way to hone my R skills. One example I am trying to work through is the following: x <- 1:20 Observed <- sample(x,20) Resamples <- replicate(1000,sample(Observed,replace=TRUE)) Boot.Means <- apply(Resamples,2,mean)

Dear All, How can I sort a data frame with respect to more than one variable? I know that for one variable X one may use: df[order(df$X), ] where df is the data frame containing X. Many thanks, Bernard --------------------------------- [[alternative HTML version deleted]]

Hello, I am trying to place a legend in the title area of a plot. I can not seem to find a way to get legend() to do this. Nor can I use the title() function. Does anyone know a way to do this? I would greatly appreciate any advice. Thanks Josue Samayoa Center for Biomolecular Science & Engineering School of Engineering Division of Physical & Biological Sciences University of

Hi, I am trying to write a function to read in a whole text file as a single string ( so I can calculate its "sha1" hash function using package "digest"). I need a single string containing the whole file, and so far I was using paste(readLines(fileName), collapse = ""). Unfortunately this function gives me warnings : incomplete final line found by readLines on
