i've heard that you can dump a plot file, and in doing so set a pixel parameter (cbx?). is anyone familar with this procedure? i would appreciate any insight. thanks, kevin

Is there any way to put an argument into an object name. For example, say I have 5 objects, model1, model2, model3, model4 and model5. I would like to make a vector of the r.squares from each model by code such as this: rsq <- summary(model1)$r.squared for(i in 2:5){ rsq <- c(rsq, summary(model%i%)$r.squared) } So I assign the first value to rsq then cycle through models 2 through

Does anyone know of any issues with nesting source() calls within multiple scripts? I have at least one script which always finds errors when I source it but runs fine when run on its own. It containd source() calls to other scripts and it seems to fail during the first nested source() command. Ken Kenneth B.

Dear R wizes, I have a data.frame of species abundances with column names consisting of 4 letter codes then an underscore and a number like this: abco_1, abco_2, abco_3, psm_1, psme_2, psme_3, etc. I would like to get an identifier for all the abco, and psme and other species etc. I used spec.fact<-substring(names(spec.count),1,4) To make a vector of the first 4 letters of

Dear R wizards, I am seeking advice on graphics in R. Specifically, how to manipulate the size and save a plot I have produced using the LDheatmap library. I confess I am relatively new to graphics in R, but I would greatly appreciate any suggestions you may have. LDheatmap produces a coloured triangular matrix of pairwise associations between 600 genetic markers in my dataset.

R-help, Whenever I try to save a plot with "savePlot" the file is not stored in my hard disk with the selected format. Several formats are set and none of them works. I just get the file name with missing extension and it can't be open with programs like Paint and Microsoft Photo Editor Th only one able to open it is "Windows Picture and Fax Viewer" plot(rnorm(10))

Hello everyone, I did some initial tests and it seems that mongrel does not support byte-range requests. Is this correct? The reason I ask is that the iPhone requires byte-range requests to work in order to stream audio or video from a web server. Thanks in advance, alan

Hi all, I am using savePlot in a loop for saving several graph but I get some graph in 553x552, some other in 1920x1119. How comes ? My data are almost all the same (same label, same xlim / ylim, almost same data. Only the color changes). I save them in bmp. Thanks for your help. Christophe

Hi the list, I used savePlot to export some eps graph but it seems that the graph file hold a bug. I include the graph.eps in a LaTeX file. Running latex is ok. But the dvi file contain some mistake, the graph overprint on some text and hide it. Then, when I try to convert it to another format, I get : Ignoring remaining special text following unkown PS operator: "SDict" Remainder

Dear All, I have some code that works in S-Plus for writing saving a graphics file to disk :- graphsheet(type = "auto", format = "WMF", file = "G:\\north0l.wmf", pages = "auto", print.background = F, orientation="landscape", color.style="color") plot(x,y) dev.off() This works fine in S-Plus. I have tried playing

I'm running R from an Xterm window is OSX-Tiger. Graphical windows appear as they should, but I'm having trouble copying from them--using cmd+c or the Copy option in the Edit menu won't place the graph in the clipboard (when I paste into a running OS X app, I get whatever was the last copied thing from a non-x11 window). Any ideas on how to copy from a xterm-launched graphical

Hi, all. I searched a lot at mailing list, installed EBImage and gtk packages, but I couldn't make this simple work: How to add a image file (jpg or bmp ou gif) to an existing plot window (not plot over the image), like the code below (pseudo function add.image): plot(1:10,1:10,main="test") image = read.X("myimage.jpg") add.image(image, x.left=2, y.bottom=4,

Plaintive squeak: Why the change? Some OS's and desktops use the extension, so forgetting it causes trouble. The new default filename keeps a filetype (as before) but the user now has to type a filetype twice (once as the type, once as extension) to get the same effect fo rtheir own filenames. And the extension isn't then checked for consistency with valid file types, so it can be

Hi, In the Windows version of R 0.65.1 I'd like to copy the results of a plot to the clipboard either as a bitmap or as a metafile. The same thing in fact as does the menu "Copy to the clipboard" provides but from the command line. I intend to use the DCOM server version of R to do plots, among other things and copy the results to the clipboard and show these on a picture box in my

Hi, I''ve configured mongrel_clusters behind an Apache 2.2 proxy using named virtual host. Session are saved as ActiveRecordSession. But the cookies created on client side doesn''t correspond to session data saved in database (keys are different). The RoR app react just like it doesn''t have a session at all. If I don''t use Apache as a proxy/load balancer

Dear R users, I would like to fit a glm with Poisson distribution and log link with a known dispersion parameter. I do not want to estimate the dispersion parameter. I know what it is, so I simply want to fix it at a constant for this and other models to follow. My simple, no covariate model is: Tall.glm<-glm(Seedling~1, family=poisson, offset(log(area)), data=tallPSME.df) I want to

Hello, When I use savePlot(filename="xy",type="eps") or savePlot(filename="xy",type="wmf") , I get the following error: Error in grid.Call("L_textBounds", as.graphicsAnnot(x$label), x$x, x$y, : Polygon edge not found (zero-width or zero-height?) This doesn't occur when I change the type to "jpeg" or "bmp". Can

Hi, I am trying to put some graphics I have generated from R on a webpage using dev2bitmap to create a bitmap, .BMP, file. When I look at my notes from 2 or 3 months ago I was successfully able to put the ACTIVE device plot result into a bitmap file using a command such as: dev2bitmap("InsectSpray.BMP") Job done! Now when I try the same command, I get the following: >
