The release notes for R 2.0.0 states: It is now possible to specify colours with a full alpha transparency channel via the new 'alpha' argument to the rgb() and hsv() functions, or as a string of the form "#RRGGBBAA". NOTE: most devices draw nothing if a colour is not opaque, but PDF and Quartz devices will render semitransparent colours. A new argument

I'm using R 2.0.1. I looked in the email archives but didn't see anything on this topic. I've noticed a surprising (to me) difference between AIC and BIC: > methods("AIC") [1] AIC.default* AIC.logLik* > methods("BIC") [1] BIC.gls* BIC.lm* BIC.lme* BIC.lmList* BIC.logLik* BIC.nls* The BIC.gls BIC.lm BIC.lme BIC.lmList and BIC.nls functions appear

I've noticed that a frequently asked question on R-help is how to sort a data frame by multiple columns. Since this question is asked so often, making this task easier for users seems a worthwhile goal. At a minimum, the following changes to the documentation would surely be helpful and reduce email postings to R-help: 1. In the "See Also" section of the help page for

I have seen a couple of posts about color schemes like those at the ColorBrewer site. Most recently: http://geography.uoregon.edu/datagraphics/color_scales.htm These color schemes can work very well for regions (bars, polygons, images, etc.) but are not very suitable for points and/or lines. Is anyone aware of research/suggestions for a color scheme to use for scatter plots? I've looked at

Full_Name: Kevin Wright Version: 1.9.0 OS: Windows 2000 Submission from: (NULL) (170.54.59.160) The html help file for the 'library' function contains this sentence: Note that installed.packages() returns... The 'installed.packages' hyperlink points to 'installed.packages.html'. The latter file does not exist for me. I suspect the link should be to

Not necessarily a bug report, but might be nice to change. I'm using R 2.0.0 on Windows 2000. The promptData function creates a .Rd file in which the 'usage' section is: \usage{data(<dataset>)} I've looked at several of the help files for various data sets. It looks like the use of 'data' is being reduced and so it might be more appropriate for promptData to

First, a disclaimer. I am not affiliatied with the SAMM package. I am only a user of the package, but I have been contacted (off list) by people requesting information about SAMM and so I am posting this information here. SAMM is software for fitting mixed models. Versions are available for both S-Plus and R. More information and downloads of the software (and manual) are available here:

I have an S-Plus library that I would like to port to R. The library sends a mix of static and dynamic output to an html file. For example cat(" ... Big block of HTML formatting code ... ") cat(dat()) cat(" More static text ") With S-Plus I can just cut and paste HTML code from other files into my S-Plus script file. This makes maintenance of the script fairly easy. The

If you've 'rediscovered the web' with Firefox (http://getfirefox.com), you might find this tip handy. Suppose you want to search the (local) R documentation for information about the lme function. Wouldn't it be nice to just type into the browser address bar: r lme and have the search performed? Here's how (on Windows): Click on this link:

R 1.9.1 requires multi-line strings to contain a backslash at the end of each line (except the last line). As noted by Mark Bravington (http://tolstoy.newcastle.edu.au/R/help/02b/5199.html) this requirement appears to be undocumented. In S-Plus 6.2, multi-line strings do not need a backslash for continuation. I recently (http://tolstoy.newcastle.edu.au/R/devel/04b/0256.html) requested

Full_Name: Kevin Wright Version: 1.8.0 OS: Windows 95 Submission from: (NULL) (170.54.59.160) This bug also happens to me using R 1.9.0 on Windows 2000. Took me a long time to create a reproducible bug, but I think I have succeeded. I suspect my test function has a bug, but I don't see anything wrong. Plus, the bug only shows up when selecting certain filenames. Nearest I can speculate,

Hi all, I'm attempting to convert all the pointers to arrays the mdct_backward function so it can be partitioned off for a hardware implementation. Although this code is quite short I'm finding it a little tricky. As it stands, mdct_backward is passed values by reference i.e. void mdct_backward(mdct_lookup *init, DATA_TYPE *in, DATA_TYPE *out) o my modified version starts void

...is scheme could not work? Are there hooks in the Vorbis stream format to tell the decoder that this as been done so that it will know to play back slower than normal?

First, a big thanks to all of the developers and users that have worked to make R such useful software. It is only because I find the software so useful that I have the following opinions. A recent post to R-devel listed the 'Top 10 Features' for one person. I found it to be quite an interesting read. Over the past couple of years I have assembled my own lists. Retrospective. Some of

I'm using R 1.7.0 on Windows 2000. I'm a long-time user of R, but am experiencing frustration because I can't figure out how to view the function definition of a non-exported method. (I know I can go view the source code or the code in the library directory but I am trying to view the function inside the R environment. In particular, library(mva) biplot.princomp Error: Oject

I've searched for a while and have not been able to find a succinct, one-page guide to the graphics parameters that control the layout of plots. I was thinking about creating one, but thought I would see if this has already been done. I'm thinking more about a visual guide to the pare parameters than a text description. Kevin Wright

I recently posted a request for a Mozilla search engine plugin for the R java search applet. Having recieved no response, I pursued this myself and came up with an alternative. I found a "bookmarklet" that was used to submit searches to Amazon. I modified the code to submit searches to the R search engine. I tested the following using Firefox 0.9 on Windows 2000. Create a
