similar to: R command line: need intelligent command history recall?

Hi all, I am really new to the R language. I am a long time Matlab and C++ user and I was "forced" to learn R because I am taking a statistics class. I am seeking to reduce the learning curve to as smooth as possible. Are there any addon/plug-in features that can reduce the learning curve, for example, the following features can be very helpful for new learners: 1. Matlab-like

I know there are several threads about IDEs for R. I've tried Tinn-R, but I am looking for an IDE (win) with a preview function that shows me the variables and the table/matrix etc. when klicking. (comparable to Matlab). Does an IDE like this exist or can't IDEs give this functionality in R? best, Michael [[alternative HTML version deleted]]

Hi all, In R GUI window, if you use "up" and "down" key, you will be able to recall the previous and next command that has been used and stored in the command history cache. But there is one inconvenience: In Matlab, you can type the first a few characters of the command that you previously used, and then press ?up" key, you will be able to get to that previous

Hi all, I need to put two different axis to one plot. On the top of the plot, I need to put one axis, with increments from left side to the right side; then at the bottom of the same plot, I need to put another axis, with increments from right side to the left side and showing a different unit. How do I do that? By the way, is there a "hold" command for plotting? If I first plot a

Hello, I have a problem finding a root of a function, which I define like this: tuki <- function(u, x, a, lambda){ if((lambda%%1>0) & u<0) {u<-(u+0i)} f <- Re(x-(a*(u)^lambda-(1-(u))^lambda)/lambda) f } What I want to do is to find the root, but without specifying the interval within which to search for it. I can do it easily in MATLAB with fsolve() or fzero() functions. I

Hi all, I've become quite enamored of R lately, and have decided to try to teach some of its basics (reading in data, manipulation and classical stats analyses) to my fellow grad students at the University of Toronto. I sent out a mass email and have already received some positive responses. One student, however, wanted to know what differentiates the routines that R uses, from those

Tinn-R (http://www.sciviews.org/Tinn-R/) is one of the topmost suggestions when googling an R-(text-)editor for Windows. However, to me it appears dissappointing that Tinn-R does not handle utf-8 (mac-roman, or any other) encoded R-scripts or, in general, text files. Besides Emacs and the R built-in editor, could you recommend a good editor for Windows, even some commmercial for a small

Hi all In two days, I am giving a small, informal workshop in our Department about using R. Initially, it was just for statistician, but surprisingly (to me anyhow) many mathematicians are also coming who have a MATLAB background. They are coming at the Workshop from a teaching perspective. They are considering using R to avoid licensing issues with MATLAB. One thing they were hoping me to

This is very strange: I want compute the following in R: g = B/D * solve(A) where B and D are quadratics so they are just a scalar number, e.g. B=t(a) %*% F %*% a; I want to multiply B/D to A^(-1), but R just does not allow me to do that and it keeps complaining that "nonconformable array, etc." I tried the following two tricks and they worked: as.numeric(B/D) * solve(A)

Full_Name: David Kesling Version: 2.9.0 OS: Windows Vista & XP sp2 Submission from: (NULL) (65.166.169.237) I upgraded to 2.9.0 on my desktop (XP) and my laptop (Vista Home Basic). The XP machine (with both Tinn-R and JGR) is running just fine... very happy. The laptop is NOT doing too well. I've had to activate the XP-compatability mode AND run Rgui as administrator... and there still

I am new comer in R.There r few IDE like Tinn R,VIM etc.I mean How to use them? Do I need to install R and then install them to use or they can work alone? Also does one install packages on R or IDEs? Can I call/use the package from IDEs? regards Parth -- Socrates, proclaimed: "I came to know one thing; that I know nothing".

Hi all, Are there any plans to add more functionality to command-line editing and history editing on the command line? In MATLAB (I know, comparisons are odious ...), you can type "p" and up-arrow on the command line and scroll through the recently entered commands beginning with "p". This is a very useful feature and something that I believe is not replicated in R. Please

Does anyone know of a method that I can get the intersection where the red and blue curves meet i.e. the value on the x-axis? x <- 1:10 y <- 10:1 plot(x,y) abline(lm(y~x),col="blue") abline(h=2.5,col="red") Muhammad

Dear R Users I would like to use optim function to optimize a function. I read help but I couldn't find what I need: is it possible to get information after each iteration, for example as there is in MATLAB: Gradient's Iteration Func-count f(x) Step-size infinity-norm 0 24 388.976

a) How can I set the recording of all windows()-history forever to "true"? I want something like windows(record = TRUE) but not just for the window that opens then, but for all windows I will open ever. b) Scrolling up in RGui (windows 2000) to see past commands is nice, but: Is it possible to type eg "wi" and the "arrow up" and see the last command that started with

Hi all, I want to use "which.max" to identify the maximum in a 2D array/matrix and I want "argmin" and return the row and column indices. But "which.max" only works for vector... Is there any convinient way to solve this problem? Thanks a lot! [[alternative HTML version deleted]]

Hi, I'm looking for the way to make vector plot over a time line. This plot, similar to the "feather plot" in Matlab, is a line in which every thick (a time value) one vector is drawn with its length proportional to one variable (wind speed, for example) and its direction to another (wind direction, for example). Any ideas? Thanks, EKS -- ---------------------------- Eduardo

Hello, Following a discussion initiated on r-devel, that mentions SciViews-R and other GUIs issues for R, I would like to make comments (and would be happy if these comments would initiate interesting initiatives). A big, big problem with SciViews-R is that a part of it is written in Visual Basic 6, a M$$$$ language, not supported any more, buggy, non transposable to other platforms, etc,
