I have two data sets, each a vector of 1000 numbers, each vector representing a distribution (i.e. 1000 numbers each of which representing a frequency at one point on a scale between 1 and 1000). For similfication, here an short version with only 5 points. a <- c(8,10,8,12,4) b <- c(7,11,8,10,5) Leaving the obvious discussion about causality aside fro a moment, I would like to see how

I am looking for a mailing list for general statistical questions that are not R related. Do you have any suggestions for lists that are busy and helpful and/or lists that you use and recommend? Thanks in advance, Ralf

Hi R Users, I need to produce a simple report consisting of some graphs and a statistic. Here simplification of it: # graphics output test a <- c(1,3,2,1,4) b <- c(2,1,1,1,2) c <- c(4,7,2,4,5) d <- rnorm(500) e <- rnorm(600) op <- par(mfrow=c(3,2)) pie(a) pie(b) pie(c) text(ks.test(d,e)) obviously, the ks.test does not make it to the output. How can this be archived by a)

I would like to plot some text in a existing plot graph. Is there a very simple way to do that. It does not need to be pretty at all (just maybe a way to center it or define a position within the plot). ( ? ) Ralf

I assume R won't easily generate nice reports (unless one starts using Sweave and LaTeX) but perhaps somebody here knows a package that can create report like output for special cases? How can I simply plot output into PDF? Perhaps you know a package I should check out? What do you guys do to create handouts (before actually publishing)? Thanks in advance, Ralf

I am a beginner in R, so please don't step on me if this is too simple. I have two data sets datax and datay for which I created a qqplot qqplot(datax,datay) but now I want a line that indicates the perfect match so that I can see how much the plot diverts from the ideal. This ideal however is not normal, so I think qqnorm and qqline cannot be applied. Perhaps you can help? Ralf

R Friends, I have data from which I would like to learn a more general (smoothened) trend by applying data smoothing methods. Data points follow a positive stepwise function. | x x | xxxxxxxx xxxxxxxx | x x |xxxx xxx xxxx | xxxxxxxxxxxxxxxxx | |

Hello dear R help group, I would like to download the tRNA data on: http://gtrnadb.ucsc.edu/download.html And then import it into R. Can anyone direct me as to how to do so?

Hello dear R help group, I am trying to read a .txt file, with Hebrew column names, while keeping the column names looking well in R - but without success. I uploaded an example file to: http://www.talgalili.com/files/aa.txt And am trying the command: read.table("http://www.talgalili.com/files/aa.txt", header = T, sep = "\t") This returns me with: X.....ª X...ª......

Hi R-fans, I would like put out a question to all R users on this list and hope it will create some feedback and discussion. 1) What are your 3 most useful R package? and 2) What R package do you still miss and why do you think it would make a useful addition? Pulling answers together for these questions will serve as a guide for new users and help people who just want to get a hint where to

After reading more, I understand I didn't formulate my last question correctly, so please allow me to rephrase: What I am looking for is a way to save the R console session output. That is, a command that would combine the results of using: ?sink # And ?savehistory My motivation for this is that doing it will allow someone who is a blind user of R to be able to easily export his results to

Hello all, The following line of code includes a right-to-left language text, yet the R graphics engine displays it from left to right. One problem this causes is when there are parenthesis in the test, here is a basic example? plot(1:10, main = "שלום (טקסט)") Is there a way to make sure the text is displayed from right to left? Many thanks for any suggestions, Tal

Hello all, I would like to recreate the plot shown here (from a useR 2009 presentation): http://www.agrocampus-ouest.fr/math/useR-2009/abstracts/pdf/Hocking.pdf I downloaded the code for that image, and discovered that it relies on external web services, and also having PERL installed on the computer. I believe this could be done "locally" using the "seqLogo"

Hello all, I am using R 2.13.0 with windows 7, after giving my user full privileges to the R folder (as described here<http://www.r-statistics.com/2011/04/how-to-upgrade-r-on-windows-7/> ). This allows me to install new packages just fine. However, when using update.packages(), to update existing packages, I keep getting the following error (for example, when updating the MASS package):

Hi all, I just failed in loading a saved wordspace (13MB of size), and received these errors: Warning: stack imbalance in 'missing', 52 then 51 Warning: stack imbalance in 'if', 50 then 53 Warning: stack imbalance in 'as.environment', 57 then 59 Warning: stack imbalance in 'ls', 54 then 53 Warning: stack imbalance in '.Internal', 54 then 53 Warning: stack

Hi everybody, I would like to count how many times names in list L, nombreL, apear in list C, nombreC. Can I improve the next program? cuenta <- 0 topL <- length(nombreL) topC <- length(nombreC) for (i in 1:topL) { for (j in 1:topC) { k <- grep(noquote(nombreL[i]),nombreC[j])

Hello all, I recently discovered the "comment" command. I see it can only hold a vector of characters. Is there a way (or an alternative), to make it possible to have it keep a list? (for example, to keep different pieces of information like date of creation, information of each variable and so on) The closest solution I can think of is using 'names' on the vector, like this:

I have written a function to emulate minitab's QQ plotting output (with SW test and AD test results on the graph): mtab.norm<-function(x) { library(nortest) library(lattice) x<-as.numeric(x) x<-as.vector(x) plot.ht<-4.6 plot.wd<-4.6 pt.ht=plot.ht/5 txt.sz<-(plot.ht/7.5) X11(width=plot.wd, height=plot.ht, bg='gray96') qqplot(x, pch=16, cex=pt.ht,

Hello all, I would like some R function that can translate a string to a "URL encoding" (see here: http://www.w3schools.com/tags/ref_urlencode.asp) Is it implemented?
