similar to: selecting a group of points from a scatterplot?

I'm trying something that I thought would be pretty simple, but it's proving quite frustrating... I want to display, for instance, the correlation coefficient "rho" in a graph. I can do something like: text(x, y, paste("rho =", cor)) where cor would be my previously calculated correlation coefficient, and x and y the coordinates. Obviously that displays

Hello list, I use R for microarray analysis. One procedure I use takes a large matrix, and loops through it looking for specific rows, does an operation with them, and outputs a result (single row) as a row of another matrix. The loop goes on about 25000 times. When I run the loop directly from the R console itself, it takes about 3 minutes in my computer. I'm ok with that. Now,

Dear list, is there a way to open a .zip folder so that one can extract and modify files inside and then save teh .zip folder again? thanks!

Hi All, I have substantially expanded the table that compares SAS and SPSS add-on modules to somewhat equivalent R packages. This new version is at: http://r4stats.com/add-on-modules and I would very much appreciate any feedback you might have on it. The site http://r4stats.com is the replacement to http://RforSASandSPSSusers.com and includes the support files for both "R for SAS and SPSS

Hi, after reading about it in the forum, I tried the Tinn-R editor (in WinXP) running R 2.5.0... nice one! However, I am trying to change the syntax-colouring from the default to my own preferences... and I can do that, but my options don't appear to be saved and get lost when I close Tinn-R. I've searched help menus, and google... and I can't find how to make sure my

Hi, I was wondering if there's a way in R to open a web browser (such as Internet Explorer, or Firefox or whatever). I'm doing some analyses that have associated urls, and it would be nice to have the ability to directly open the relevant page from within R. I was looking at the help for 'url' and I can see I can probably access the information I need and display it in my

I have just started using the package 'rgl' to explore my data as a 3D scatterplot. It's a great tool. But I would like to be able to save some graph views and it appears the only format available is 'png' and it doesn't look that nice. It is excellent to work with on screen and explore/play, but when it comes to producing a good quality graphic I'm a bit

Hello Rusers, I have worked on a R Wiki page for solutions in exporting R graphs, especially, the often-asked questions: - How can I export R graphs in vectorized format (EMF) for inclusion in MS Word or OpenOffice outside of Windows? - What is the best solution(s) for post-editing/annotating R graphs. The page is at: http://wiki.r-project.org/rwiki/doku.php?id=tips:graphics-misc:export. I

Hi, I have been using 'read.table' regularly to read tab-delimited text files with data. No problem, until now. Now I have a file that appeared to have read fine, and the data inside looks correct (structure etc), except I only had 15000+ rows out of the expected 24000. Using 'readLines' instead, and breaking up the data by tabs, gives me the expected result. I do not

Hello, I am trying to execute an example provided in the help files for the playwith() function. I try to execute the first example: library(playwith) if (interactive()) { options(device.ask.default = FALSE) ## Scatterplot (Lattice graphics). ## Labels are taken from rownames of data. ## Just click on the plot to identify points. playwith(xyplot(Income ~ log(Population / Area), data =

Hi everyone, I hope there's a simple way to achieve what I want, but I haven't found the way. I do microarray analysis using R and a number of packages as well as some functions created my myself. When I save the workspace, it saves all the data structures, that's great... But when I click (I'm on Windows XP, if it matters) on teh resulting .RData file, I have to reload

Is there a package (other than xgobi which requires an X server) that will do scatterplot brushing? I see a mention in the mail archive of R-orca by Anthony Rossini but it is not in the current list of packages. My OS is Windows XP version 5.1, service pack 2 R version 2.4.1 (2006-12-18) Thanks [[alternative HTML version deleted]]

Hi List, This is possibly a newbie error. I have however searched long and hard and haven't found a solution. I am attempting to plot multiple lattice graphs in R, plotting 4 per page and moving on to a new device to plot the next 4 and so on. (I want to do this in R and not export to a pdf etc) I notice that in S-PLUS multiple tabs are opened in one device, R does not seem to have this

Hi, in approximately one months time mentoring institutions can propose projects for the Google Summer of Code 2009, see http://code.google.com/soc/ Last year the R Foundation succesfully participated with 4 projects, see http://www.r-project.org/SoC08/ for details. We want to participate again this year. Our project proposals will be managed by Manuel Eugster (email address in CC). Manuel

A new package, *latticist*, is available now from CRAN. Latticist is a graphical user interface for exploratory visualisation. It is primarily an interface to the Lattice graphics system, but also produces displays from the vcd package for categorical data. Given a multivariate dataset (either a data frame or a table), Latticist attempts to produce useful displays based on the properties of the

As per a request, here is a brief guide to what is available to R users as packages in Ubuntu. Each release of Ubuntu includes the latest version of R and the recommended packages. In addition, there are approximately 80 additional r-cran packages available in the default repositories. The limitation to these packages is that they are not updated and reflect the current version of the

Hello, I am having trouble installing the package playwith on the latest Mint "helena", running R version 2.10.1 (2009-12-14). I suspect it has to do with the GTK library but as far as I can tell there is nothing wrong with it. Any help extremely appreciated.
