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......

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:

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

This is copy & paste from my session: > xyz<-as.vector(c(ls(),as.matrix(lapply(ls(),class)))) > dim(xyz)<-c(length(xyz)/2,2) > > allobj<-function(){ + xyz<-as.vector(c(ls(),as.matrix(lapply(ls(),class)))); + dim(xyz)<-c(length(xyz)/2,2); + return(xyz) + } > xyz       [,1]              [,2]        [1,] "a"               "character"  [2,]

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, 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):
