Hello, I very much enjoy "with" and "subset" semantics for data frames and was wondering if we could have something similar with split, basically by evaluating the second argument "with" the data frame : split.data.frame function(x, f, drop = FALSE, ...){ call <- match.call( ) fcall <- call( "with", data = call[["x"]],

Hi everybody, I would like to ask if it is possible using pdf function or some other to print plots in cycle such that every new plot is on new page. like this pdf(file="D:/Plot.pdf",width = 9.25,height=9.25, family="Helvetica",pointsize=8,bg="white") for (i in 1:10){ x <- seq(1,40,1) y <- 2*x+1+5*rnorm(length(x)) hist(y,freq = FALSE) plot(density(y)) }

Dear R helpers,   I am working on the scenario analysis pertaining to various interest rates. In this connection I need to form the various combinations as under :   Suppose I have two sets A = (a, b, c) and B = (x,y,z)   Then I can easily form the cominations as (ax, ay, az, bx, by, bz, cx, cy, cz)   However, if I have say 5 variables, then total no of possible combinations will be 3^5 = 243.

Hi, I am Linux Ubuntu 9.04 user. I'm using R-2.6. Actually, I am developing R package for reading/writing 3D images. I needed to use the R package Rcpp in order to make profit of available C/C++ codes. My problem is that my C code is not able to include the Rcpp.h In fact, when I run this command R CMD build rply, I got the following error message in the file

Hello, I have the following problem when trying to use rm: In a top level script file I have a loop iterating over some index. The loop is not contained within a function, so the scope of variables declared in the loop is global. Within this loop I generate several variables which should be removed at the end of each iteration. To do this, I wrote a function to clean up the workspace. An example

Hi, I am looking for a R package which is capable to process and analysis pictures of tissues (stained) in an automatic way. I had a look on biops and EBImage (Bioconductor) but they are not automatic... Did you already use/know a such package ? Thanks, - Martial _________________________________________________________________ Tchattez en direct en en vidéo avec vos amis !

Hello, I've written a brush for R for the SyntaxHighlighter JavaScript library. It allows you to display R code on a web page with the proper syntax highlighting. It's available here: http://demitri.com/code Comments and suggestions for improvement are welcome! Cheers, Demitri

Dear All, I have a correlation matrix say 'M' (4000x4000) for 4000 genes and I want to subset it to 'N' (190x190) for 190 genes. The list of those 190 genes are in variable 't'. So the idea is to read the names of genes from variable 't' and subset the matrix M accordingly. Any thoughts are welcome! Best Lee [[alternative HTML version deleted]]

Hello, I have some problems to migrate to R >3.0 my devel machine (R.2.15.2). So I decided to start from scratch with a brand new virtual machine. Downloaded latest network install of debian testing, not stable (jessie/sid, SMP Debian 3.16.3-2 (2014-09-20) x86_64 GNU/Linux) installed only with ssh-server and basic utilities (no X). Then I installed R by: apt-get install

Hello everyone, I just showed a friend a prototype of a site offering a service I''m trying to sell (sorry, not on the Internet yet - he saw it at my house). His comment: "Looks like it does everything, but also looks pretty ugly. You''re not going to wow anybody with that". Sitting back and thinking about it, he''s dead right - it needs some bling to make it

Dear all, i am new in R. I am writing a review paper about batteries. However, i am interested in analyzing all the papers by keywords, author, references and year. This could be done by "refviz" a software, which is only running on windows machines and which is not free. So my question to you is, is it somehow possible to write a script that can do all of this work? And if yes, with

Hello, I apologize that I am cross posting here after getting no answer from my initial question on stack overflow <http://stackoverflow.com/questions/33492601/r-setoldclass-only-if-needed>. I should certainly have posted it first here.. I am using 3 packages: - xts - quantmod - 'myPackage' quantmod is creating a union class by doing: setOldClass("xts");

Dear Michael, my package has setOldClass("inla") and the NAMESPACE contains exportClasses(inla) and importFrom(INLA, inla.posterior.sample) the old version of INLA uses the S3 class "inla" but does not export it. the new version of INLA has setOldClass("inla") and the NAMESPACE contains exportClasses(inla) installing my package in combination with an older INLA

I am new to using S4 methods and have run into this problem (on Windows XP using R 2.4.1): I am writing a package in which I use the graph package. I define my own classes of graphs as: setOldClass("graphsh") setOldClass("ugsh") setIs("ugsh", "graphsh") (I know that I "should have" used setClass instead - and I will eventually - but right now

Hello, I am the maintainer of the stringkernels package and have come across a problem with using S3 objects in my S4 classes. Specifically, I have an S4 class with a slot that takes a text corpus as a list of character vectors. tm (version 0.5) saves corpora as lists with a class attribute of c("VCorpus", "Corpus", "list"). I don't actually need the

Dear all, Today I got this error message (R 3.6.1) when installing my package: Error: package or namespace load failed for ?inlatools? in namespaceExport(ns, exports): undefined exports: .__C__inla My package was using setOldClass("inla") and exported the "inla" class via the NAMESPACE. It imports functions from the INLA package. Older versions of the INLA package did not

The package I'm working on can extract data from external packages but would otherwise have no dependency on them. However, I desire to be able to dispatch based on an external S3 class if its package is attached (.First.lib). My code is S4-based and its package has NAMESPACE. Registering the external class prior to the other package being attached doesn't seem to work so I am attempting

Hello, I am writing an interface to some functions from the CRAN package pamr, which is poorly written. I have a S4 method I declared with setMethod. I'd like to provide a signature of "pamrtrained" which is the class of object that training creates. The last two lines of code of pamr.train are : class(junk) = "pamrtrained" junk How can I dispatch on these kinds
