Hi I get a matrix with the columns named like "X13 X22 X1 X14 ...", i.e. not successively. That has it's good reasons, but now how can I rename the columns to "X1 X2 X3 ..."? Thanks a lot, David

Hi I am trying to replicate a vector in n rows for comparison purposes with another matrix. foo <- c(1,2,3) bar <- rbind(foo,foo) # does the trick for 2 rows bar <- rbind(rep(foo,2)) # does something else How do I generate a matrix with all rows=foo without writing 'foo' n times as arg? Thanks, David

Hi cor(x,apply(x,1,sum)) gives me the correlations of each column with the sums of each row (correct me if I'm wrong, please). What I need are the correlations of each column with the sums of each row except the entry in the given column. It seems that for any one column i I get it by doing: cor(x[,i],apply(x[,-i],1,sum)) But I struggle to get it for all the columns. I was trying things

Dear list I am comparing the results of several different experimental setups. With kruskal.test() I can test if there is any difference at all in any of them, if I understand it correctly. But now, when there is a difference, how do I generate a (half-) table of pairwise comparisons, using e.g. wilcox.test(), to find the ones where the difference actually occurs. I guess I don't have to

Hi I have a matrix of type "character" (strangly) and am trying to apply the function "aggregate" to it, but unfortunately without success. It seems to me that aggregate would work, if I only could get rid of the quotation marks around each item. So for a very simple example which looks as my actual data look (of course here I put the quotation marks on purpose, but I have

Dear all! After hours of trying around, I gave up: I have a 2-dimensional array, and I know how to split it into its rows and how to get the mean for every row using 'sapply'. But what I want is to calculate the mean over the first n rows, and then the second n rows, etc., so that I get a vector like: v == mean1(row 1:5), mean2(row6:10),... (trivial, you might say. I find it rather

Dear all, I would like to use the biological symbols for male and female as plotting symbols in a scatterplot (ideally filled and non-filled). R does not seem to have these symbols using pch= in plot() nor are they implemented via expression() or at least I did not find them. I found that the symbols are e.g. available in the wasysym and the marvosym package in LaTeX. I have coded two very rough

Hi, there! I finally became a disciple of 'R', after having lost years of my life handling data with a popular, rather wide-spread spreadsheet-software. Now I want to plot the results of many runs of my simulation over time, so that the means +/- Standard error are on the y-axis, and time on the x-axis. I have tried 'boxplot', with timesteps as the grouping variable, but did

I'm using an SVM as I've seen a paper that reported extremely good results. I'm not having such luck. I'm also interested in ideas for other approaches to the problem that can also be applied to general problems (no assuming that we're looking for spirals). Here is my code: library(mlbench) library(e1071) raw <- mlbench.spirals(194, 2) spiral <-

Dear all, this is a rather basic question; i am not sure how to structure my data well: I want to extraxt various measures from my raw-data. These measures are of different sizes, so I decided to store them in a list, like: run1 <- list(Dom = (my_vector), mean = (my_single_number)) I can do that in a for loop for 40 runs, ending up with 40 lists: run1, run2, ..., run40. To have all the

Hi, Another question about graphics... Suppose I have: par(mfrow = c(4, 6)) which will set up a figure region for 24 plots. But, I actually only need 23 plots. In fact I wrote a little function, foo.plot, which will draw all the 23 plots at once with: foo.plot(x) where x is a data frame. Now, suppose I want to draw several set of these 23 plots, but want to put them all in one postscript

Is there any way to change the orientation of the labels on the end of the dendrograms to horizontal rather than vertical? If so, how can I do that. _____________________________________________ Patrick Richardson Biostatistician - Program of Translational Medicine Van Andel Research Institute - Webb Lab 333 Bostwick Avenue NE Grand Rapids, MI 49503 ph. 616.234.5787 This email message,

Hi, ESS replaces "_" by "<-". How can I switch off this feature? I need to be able to type the underscore Thanks Eryk -- Witold Eryk Wolski Heidmark str 5 D-28329 Bremen tel.: 04215261837

Dear all, I would like to compare two distance matrices to find the correlation between those and create a XY plot.could you please kindly help me and let me know how I can do that using R.(Mantel test?). Your help is very much appreciated!! Many thanks! Regards, Sima Fakheran ............................................................... Sima Fakheran Esfahani PhD Student Institute of

Dear R People: I have finally seen the error of my ways and have decided to use ESS for R and S + stuff. However, I have a question right from the beginning. I'm somewhat confused by the installation instructions. Do I install XEMACS or ESS first, please? Windows XP R Version 2.0.1 (S + 6.2) Thanks so much! Sincerely, Laura Holt mailto: lauraholt_983 at hotmail.com

Dear R users, I downloaded an ess-5.2.2 package and hope to use emacs as front to work with R. I modified ~/.emacs and start R by M-x R. But I found when I quited the R session, it still asked me to save the work space or not. I added inferior-R-args with "--save" args. But it seemed that it had no effect. Can you tell me how to pass the arguments other than --no-readline to

Hi Everyone, I am a beginner running R 2.9.2 under Ubuntu and typically use Emacs w/ESS. However, I am confused with history() command. When I issue command history() in Emacs within an R session, this is what get: > history() Error in savehistory(file) : no history available to save Similarly, history(max=10) command gives the same error message. However, there is this In/Out Menu in the

Im running R 0.99 on SuSE 6.3 with Linux 2.2.14 and Xemacs 21.1. When I try to compile ESS the processes stops with an error message: Making info file `ess.info' from `ess.texi'. ./newfeat.texi:3: itemize requires an argument: the formatter for @item. ./newfeat.texi:9: itemize requires an argument: the formatter for @item. makeinfo: Removing output file

Hi all, I don't know if this is the proper place to ask this, but I am trying to configure emacs/ess on Ubuntu 8.04 to run the way described for ESS and Xemacs in Windows (John Fox's guide). I installed ess as directed at http://ess.r-project.org/Manual/ . Under Windows I could use Emacs/ess fine (but I am obviously a novice at emacs), but am having trouble doing so in Ubuntu. At
