Hi List, I want replace characters within a vector. Outside R I could use sed, but I'd like to automate it in R. For example vectorx xxxyyz xxxyyza xxxyyzzb I want to change to: vectorx aaayyz aaayyza aaayyzzb The obvious replace command only deals with whole data entries? Any hints would be appreciated. Thanks Herry

Dear statisticians, I would like to save results for a "for loop" in a vector previously created. My result would be of class "matrix". I tried the following script: Script: #Creation of a previous vector n.Tree<-2 VectorX<-rep(1,n.Tree) #loop for (i in 1:2) { Ti<-MatOccurTree[Tree[i],1] #number of observation for Tree i Xi<-matrix(data=1,nrow=Ti,ncol=2)

I hae tried searching the web for the answer, but, man is there a lot of pages ... :( in the language I develop in, if I have a structure I can dynamically refer to the contents of a field of the structure like so: MESSAGE SomeStructure:Field(SomeFieldName):Value where SomeFieldName is either a quoted constant or a variable expressions In "C", I beleive that you can refer to

Dear list, I'm using the Sweave function in order to get some report. Here one chunk: <<echo=F,results=tex>>= report<-lapply(repor, function(x) { (print(xtable(data.frame(x[1:2,]), align="|l|rrr|"),floating=FALSE,tabular. environment="longtable",include.colnames=FALSE,size="\\small"))

Hi, my mapstraction onclick event handlers always yielded javascript errors in Virtual Earth maps ("e.view is undefined"). I''m using version 6 of mapcontrol.ashx. After consulting Virtual Earth documentation, I came up with a solution. Here is my patch (based on rev 212) > var that = this; 360c361,368 < me.clickHandler(e.view.LatLong.Latitude,

Hi, I want to generate a number of vectors and store them with different names, like this: x=1 while (x<100) { vector#x# = rnorm(100) x=x+1 } where each vector has, at its hand, instead of #x# a number which goes from 1 to 99. How can I do this? Thanks Gabriele Zoppoli, MD Ph.D. Fellow, Experimental and Clinical Oncology and Hematology, University of Genova, Genova, Italy Guest

Hi, I want to create a pdf of my Man-pages from my package. Therefore I run in the terminal Rd2pdf on the package and a pdf of all the pages is created. After the titlepage there is the general package page, which includes "Description" and "Details" etc. Unfortunately after the Subtitle "Details" there is a pagebreak (and 3/4 white page) which I did not set

Hi, I noticed that the R reference manual seems to be missing the license permissions on the copyright page. Below is a patch to "refman.top" which adds the same permissions as the @permission{} macro in "R-defs.texi". I'm filing this bug as I have been preparing to publish the R Reference Manual (in several volumes). I plan to donate 5 EUR to the R-foundation for each

Hi! Pretty low content question but I've had major trouble finding an answer for it so I hope it's alright. I'm obviously new to R, and have been trying to get rid of the numerated output I get in the console. What I mean more specifically is that X<-4;X comes out as [1] 4 and I'd like to get rid of the listing [1]. This isn't usually a problem when working with the

Is there a way of doing this? I'm using plot() to produce a scatter of my data, but it routinely defaults to plotting 2 sets of x axes and 2 y axes. I'd like to not plot the upper and rightmost axes. I can use 'axes=F', and then manually add axes with 'axis', but then the newly created axes do not intercept. TIA, Dan

I recently noticed some anomalies in the Mocha RDoc. Within a method RDoc comment, any word that happens to be the same as a method in the same class gets turned into a link. You can see an example [2] with the word "once" and another [3] with the words "yields", "times" and "with". Does anyone know how to stop these words incorrectly being made into

Hi! Why do I still get an error message on the try function?: > options(show.error.messages = FALSE) > > trab <-matrix(nrow=6,ncol=6) > trab[,] <-0.0001 > rownames(trab) <- c("A","B","C","D","E","I") > colnames(trab) <-

Hello, I've got roaming profiles set up on my machines, that load and run netlogon scripts that do various things. I would like there output suppressed, i.e. I don't want to even see the dos box, I just want the things to do there job and go on. Is this possible? Thanks.

I'm trying to display my deciles without scientific notation, but have not found an option that will allow me to do so. According to web searches, the options(scipen=999) should remove scientific notation, but it seems not too. Does this option work with quantcut function? Is there any other option that can be used? I am using verison 2.10.0. library(gtools) library(gdata)

Dear R list, I have a dataset with a column which should be read as character, like this: name surname answer 1 xx yyy "00100" 2 rrr hhh "01" When reading this dataset with read.table, I get 1 xx yyy 100 2 rrr hhh 1 The string column consists in answers to multiple choice questions, not all having the same number of answers. I could format the

Hello, I want to do simulations with an external simulation model. For this purpose I wrote a R-script which makes the pre- and post-processing of the data (generate scenarios, analyze results). The R-script writes the input file for the simulation with e.g. write(x, file="test.dat", ncolumns=10) The problem is, however, that this command (and even constructions with cat) will add a

Hi Attached is a patch to add HtmlWindow and some of its friends, including HtmlEasyPrinting. Also a sample. I haven''t tried exposing the parsing and rendering API yet to allow custom tags etc - I just wanted to get basic HTML and the 0.6.0 compatibility classes first. There may well be some quite easy classes left. There''s one ugly kludge to get OnOpeningURL to compile -

i have a time Series of IBM closing px from 1/1/2000 to today I want to graph the time serie by dividing the graph by year and month all the monthly graphs with the same year will go to one page. so from 1/1/2000 to 11/19/2010. i will have 11 pages, and each page will have 12 graphs (jan to dec) except for 2010. I am able to do it in R, but when i use sweave, I can only print the last page.

Dear R Users, I am trying to suppress the information printed by the ecdf function during an assignment. Various alternatives have failed me so far: > a=summary(ecdf(rnorm(100)))["1st Qu."] Empirical CDF: 100 unique values with summary > invisible(a=summary(ecdf(rnorm(100)))["1st Qu."]) Empirical CDF: 100 unique values with summary > (function()

Hi, I'm currently trying to find and fix memory leaks (compiling with ``-fsanitize=address``) in the KLEE tool [1] an having found some leaks and I'm having trouble suppressing them. I'm trying to suppress them using the ``-fsanitize-blacklist=blacklist.txt`` option as documented at [2]. I'm using Clang 3.7 ( Arch Linux package 3.7.0-6). The sort of reported leaks I see are ```
