Hi all, I have created following codes : mat = cbind(c(0.000059710430,0.000023057380), c(0.000023057380, 0.00005971089)) set.seed = 1000 vary = runif(dim(mat)[1], 2000, 3000) calc = function(mat, vary) { result = vector(length = (length(vary)+1)) result[1] = sqrt(t(vary) %*% vary) for (i in 1 : length(vary)) { result[(i+1)] = sum(vary)*sum(vary*mat[,i])

Dear all, I am looking for some kind of interactive plot to draw a histogram for a normal distribution with different sample size. In that plot there would be some sort of "scroll-bar" which will take min value 10 and maximum value of 10,000 as sample size (n) from a standard normal distribution. In that case user will scroll in that scroll bar and histogram with different sample

Hi all, I have an array of 10000 x 200 x 200 numbers... which is a time-series of 200x200 2D data... The 1st dimension is the time index. Is there a way to make a movie out of these data - i.e. playback 10000 frames(200x200) at a playback rate per second? Thanks a lot! [[alternative HTML version deleted]]

Hello, I am trying to build some dialog boxes but I am having problems. I'm using R-2.13.1 in Windows 7 I want to have 4 numerical entry boxes and 3 radiobuttons in a row ( 4 rows) for entry data and 2 rows for output with a button for 'compute' and another for ;quit' Can somebody indicate a tutorial or an example with similar type of dialogs? Thanks R.Heberto Ghezzo Ph.D.

if i want to plot the chi-square distribution with a different degree of freedom how can i plot it in the graph?Sometimes i plot the histogram and cut it in a lot of piece.It's distribution like a chi-square.So i want to plot the chi-square with a different degree of freedom to compare it . -- View this message in context:

Hello! I want to create a command for choosing input parameters via a new window that shows a table in which the parameters can be written in. R should open a seperate window in which the user is asked to put in some values (just numbers), afterwards a new file containing these values should be created and saved in the working directory. Does anybody how I can solve that problem and which package

Dear All I want to plot a kind of figures, which can interactive with user. For example, i have a matirx which can be showed by image function. i.e. we can compare the value depend on different colors. However, the change of colors depend on the range of value. Nowaday, i want to set a bar, which can be moved by user such that the user can obtain the appropriate range. Does anyone suggest me which

I'd like to provide a simple user capability of choosing some parameters that I could grab to generate a graph. User would be selecting choices via radio buttons etc via a web browser. I work in a Windows environment.

Hi, I would like to get all X iterations in optim output in matrix form. I know about the follow approach: sink("reportOptim") optim( ......., control=list( trace=6,..........) ) sink() all_iterOptim <- readLines("reportOptim") unlink("reportOptim") all_iterOptim <- all_iterOptim[ grep( '^X', all_iterOptim ) ] ### TODO: the rest !!! :-) But it is very

...but still not block in the automatic checking. I recommend running "example" with the argument "ask=FALSE", otherwise you will need to hit enter 2-4 times each time a diolog pops up and every time you update something in the dialog. There are several new functions including: tkexamp, a tool for creating interactive Tk based examples of what options to functions do (mainly for plots, but one example shows a non-plotting function). dynIdentify and TkIdentify, tools that create a scatterplot with labels, then allow you to drag the labels with the mouse to better locations. col2...

How I can vary the parameters for a function? I have a function with 5 parameters I want to turn the function for a range of numbers for one of these parameters!! i want to have in the end the value of the function in the different cas of one of the paramter (the others paramters are fixes!!) thank you for your help [[alternative HTML version deleted]]

Hello, I need to design a fairly simple front-end for someone to use an R script system that I've built. My thought was to just use the text based menus available in the base R package, perhaps in some kind of loop. How have other people done this? Any "best practices" that you can recommend? Thanks! -- Noah Silverman UCLA Department of Statistics 8117 Math Sciences Building

I'm making some 3D plots with contour3d from misc3d and wireframe from lattice. I want to view them from below; i.e. the negative z-axis. I can't figure out how to do so. I would like my point of view looking up from below, with the z, y, and x axes positive going away. Can anyone tell me the correct settings for screen to achieve this? Here is what I've found so far:

Hi R, I have a an excel file with a lot of data. I need to create an user interface in R, which has one single screen. It needs to contain a right pane containing the click buttons for different countries (say). If the user clicks a country, then a chart needs to be created for that country, taking the data from Excel. Is this possible and which package helps me in doing this? Many thanks in

Hi, I am looking for a R package to draw 3d plot. But not in a static way like scatterplot3d or stuff like that. I would like to make rotate the plot, to zoom/unzoom etc..., actually to render the graph 'dynamic'... (for the biologist and bioinformatician, a R package which permitts to reproduce what pdb viewer does). Does a Way exist to do something like that in R ? Thanks,

Hi, I'm looking for a manual (we based or pdf) which would explain in detail with graphical examples what all the option can do in plot and par. Does anybody now anything like this? A couple of manuals to R I went through do have plot parameters mentioned, but sometimes it is hard to understand or imagine what the parameter can do (the same with the related help page) e.g. I met "From

In an R graphic, I'm using cond.col <- c("green", "yellow", "red") to represent a quantitative variable, where green means 'OK', yellow represents 'warning' and red represents 'danger'. Using these particular color names, in B/W, red is darkest and yellow is lightest. I'd like to find color designations to replace yellow and

Hi, all, I would like to know if there is any gui interface out there (academic or commercial) that allows one to edit R-language generated graphs (e.g positioning x axis labels.) It would be nice to have something like the user interface of Igor or Origin. I have already used JGR and R-gui. These are good, but they don't allow one to easily edit graphs. I have also tried
