I'm writing a couple of related functions, and I'd like to generate a (single) .R file (containing the function definitions), and separate .Rd files (documenting each function). Would this be possible with Sweave/noewb? Has anyone tried something along this idea? -- Regards, Bj?rn-Helge Mevik

As of R 1.7.0, princomp no longer accept matrices with more coloumns than rows. I'm curious: Why was this decision made? I work a lot with data where more coloumns than rows is more of a rule than an exception (for instance spectroscopic data). To me, princomp have two advantages above prcomp: 1) It has a predict method, and 2) it has a biplot method. A biplot method shouldn't be too

Dear developeRs, I've searched the documentation, FAQ, and mailing lists, but haven't found the answer(*) to the following: When should one specify LazyLoad, LazyData, and ZipData? And what is the default if they are left unspecified? (*)Except that 1) If the package you are writing uses the methods package, specify LazyLoad: yes, and 2) The optional ZipData field controls whether the

Allowing for messages in non-ASCII encodings would probably be a good idea, but I think allowing non-ASCII variable names is dangerous. -- Regards, Bj?rn-Helge Mevik

I'm using R for calculations and plots in a statistical paper. Is there a canonical reference to use in the bibliography?

Dear developeRs, As of icc 10, the -c99 option is deprecated, and generates a lot of warnings when compiling R or R packages. If you use CC="icc -std=c99" instead of just CC="icc", R's configure will not add the -c99 option, and the code seems to compile and run just fine. (Please don't hesitate to let me know if this is a bad idea. :-) -- Regards, Bj?rn-Helge

As far as I can tell, there are no facilities in the "base" R for image analysis. Is there any extension or package for R that implements image analysis? I'm thinking of features such as o Reading and writing image files, o displaying indexed or "true color" images, o resizing, cropping, etc, of images, o filters for manipulating images (smoothing, edge detection, etc) o

Dear developeRs, I use Red Hat Enterprise Linux WS release 4 (Nahant Update 2) on an x86_64 machine (two Intel P4 CPUs with 64 bit support), and R-beta_2005-12-12_r36712.tar.gz. If I run configure without any options, it does not list tcltk among the supported interfaces: ./configure [...] R is now configured for x86_64-unknown-linux-gnu Source directory: .

Dear developeRs, I have a package, pls, that implements package options. The users are supposed to use a function pls.options() to manipulate them. If a user changes the options, they are stored in .GlobalEnv. I was recently informed that this is against current CRAN submission policies, so I need to change that. I have looked at several different packages that implement package options, and

Greetings. I'm trying to recreate in R some regression models I've done in SAS, but I'm not getting the same results. My advisor suspects this may be due to differences in precision between R and SAS. Does anyone know where I can find specifications for R's type double? (It doesn't seem to be in the R Language Definition.) Thanks in advance for any help anyone can

Dear developeRs, I'm trying to build R (2.7.1, on an x86_64 running Linux, but I believe I have observed this on x86 and with earlier versions of R as well) using external BLAS and LAPACK libraries _and_ generating libR.so, libRblas.so and libRlapack.so. Without --enable-BLAS-shlib, configure is able to find and use the external LAPACK library: ./configure \

In the "old days", one way of speeding up matrix calculations was to drop the dimnames of the matrices prior to the calculations, i.e., dimnames(X) <- NULL. I distinctly remember that this could have a great impact at least in Splus 3.x (under UNIX/Linux). I just did a small, informal test of this with a couple of functions I use to fit plsr models, in R 2.3.0 (Linux). It

The installation of R I'm using (R 1.2.0 on Redhat Linux (R-base-1.2.0-2.i386.rpm)) apparently expects to find tcl in ./share/tcl8.0, ./share/tcl8.0 or /usr/local/share/tcl8.0: > library (tcltk) Error in firstlib(which.lib.loc, package) : Can't find a usable init.tcl in the following directories: ./share/tcl8.0 ./share/tcl8.0 /usr/local/share/tcl8.0 However, tcl is installed in

We recently discovered that since R 3.3.0, on our CentOS 6 based cluster, R gets built without TIFF support. The last version where TIFF support was built, was 3.2.5. We have libtiff 3.9.4 installed: $ rpm -q libtiff-devel libtiff-devel-3.9.4-21.el6_8.x86_64 (Since CentOS 6 is so old, we have manually installed newer versions of some dependencies: curl 7.46.0, zlib 1.2.8, bzip2 1.0.6, xz 5.2.2

Dear all, apply(X, MARGIN, FUN, ...) returns an array of dimension c(n, dim(X)[MARGIN]) when FUN returns a vector of length n > 1. Matrices and arrays are also vectors, so if FUN returns a matrix or an array, apply returns an array of dimension c(n, dim(X)[MARGIN]) as above. This is in accordance with the description of apply in the Blue Book, and also how Splus works (at least v6.0). I am

Hi All, would appreciate an answer on this if you have a moment; Is there a function (before I try and write it !) that allows the input of a covariance or correlation matrix to calculate PCA, rather than the actual data as in princomp() Regards Glenn [[alternative HTML version deleted]]
