Is there a way to have 'comment' keep a list?
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:

My goal is to be able to easily create docs from R, but to be able to share it with other researchers (who do not use LaTeX) so they could easily copy/paste the tables and edit them for

Capturing R console output into a file (sink+savehistory ??)
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

Is it possible to "right align" text in R graphics?
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?

Windows 7, update.packages problem: "unable to move temporary installation"?

Which version control system to learn for managing R projects?
Hello all, I wish to learn a version control system for managing my R (data analysis) projects. I know of SVN and github, and wonder if there is any reason for which I should prefer the one over the other (or any other platform). An example for a reason could be if it will make it easier for me to later work with R-forge or CRAN or any other platform for R code distribution. Thanks, Tal

Subversion graphical client?
Hi All - I notice that most of the Rails team are using Mac OS X and TextMate for Ruby development. I too am working on Mac OS X and trying TextMate and (shudder?) EMacs. I was wondering about version control. Are folks using Subversion? If so, are they using a graphical client? Which one do they recommend? Yours, Jordan -- Posted via http://www.ruby-forum.com/.

Why is vector assignment in R recreates the entire vector ?
Hello all, A friend recently brought to my attention that vector assignment actually recreates the entire vector on which the assignment is performed. So for example, the code: x[10]<- NA # The original call (short version) Is really doing this: x<- replace(x, list=10, values=NA) # The original call (long version) # assigning a whole new vector to x Which is actually doing this: x<-
