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]]

I haven't been able to connect to http://bugs.r-project.org the last few days. Is there a problem with the site (or am I having a problem :-) ? -- Bj??rn-Helge Mevik

...If the package you are writing uses the methods package, specify LazyLoad: yes, and 2) The optional ZipData field controls whether the automatic Windows build will zip up the data directory or no: set this to no if your package will not work with a zipped data directory. -- Sincerely, Bj?rn-Helge Mevik

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

...plement (I believe I've seen one on R-help). A predict method seems to be more difficult, because the prcomp object doesn't include the means that need to be subtracted from the new data. Would it break conformance with S to let prcomp return the means as well? -- Sincerely, Bj?rn-Helge Mevik

Actually, we'll be discussing tools to make packages in general that can work in both S-PLUS and R, and also how to make some S-PLUS-only libraries available in an open-source...

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 want to build R optimized, with either MKL, OpenBLAS or ATLAS. My OS: Fedora 22 Hardware: CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 8 Thread(s) per core: 2 Vendor ID: GenuineIntel Model name: Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz I am a little confused when it comes to choose a method and would like to hear your experiences. If I am right, I have 3 possibilities: -

hi R help group, I have installed PLS package in R and use it for princomp & prcomp commands for calculating PCA using its example file(USArrests example). But How I can use PLS for Partial least square, R square, mvrCv one more think how i can import external file in R. When I use plsr, R2, RMSEP it show error could not find function plsr, RMSEP etc. How I can calculate PLS, R2, RMSEP, PCR,

Is there a bug in the configure script, is the "R Installation and Administration" not up to date, or is it me that misunderstands something here? -- Regards, Bj?rn-Helge Mevik -------------- next part -------------- A non-text attachment was scrubbed...
