Finding functions in uninstalled libraries
(Many thanks to David Barron & Jonathan Baron for pointing me to 'recode' in the 'car' package). I think I've been told this before, but how do I search for a function/keyword in libraries I don't yet have installed? (ie. on the CRAN site I tried the search engines with "recode" etc., but didn't pick up the car package this way) Stuart Dr Stuart Leask

an info on 3d representation
Dear list, sorry to waste your time. I downloaded R and I like it very much. However, my main interest is in plotting 3D graphics form imported data (points and lines in a 3d space). I imported data in a very elegant way but I wasn't able to find in R something similar to the simple "splot" function of WGNUplot (I don't need persp, image, contour: my values are not

Passing names of variables to functions
Hi, I am still new to R and have a programming question. I have created a small function which takes a parameter. In the function I want to be able to refer to the names of the variables sent to the function (specifically I want to be able to use the name of the variable given to the function in an output table). For example, in the following (fictional) function I want some way of printing

help in a separate window under linux
Hi there. R v1.3.0, Slackware linux 7.1 or Windows 98SE, PII 266, 64Mb RAM. I notice that under windows, R puts help info (ie. the response to '?<function>') into a new window, whereas under linux, it puts it into the main console window. I find the former much more helpful when checking a function's syntax. Is there a simple way of configuring R under linux to put its help

Fw: write.table only writes the first 256 variables/columns
Thanks. I was "believing" an Excel import of the file - as you say, a re-import into R still has 333 columns. I shall look elsewhere for the cause of the mysterious truncation.

R GUI For Which User?
I also agree with Philippe Grosjean that there is a need to investigate the effects of different types of GUIs on software "usability". To do that, however, there is a need to develop a set of appropriate metrics, and to understand that the appropriateness of a given metric (and ultimately a given type of GUI) is likely to be conditional on the type of user. My sense is that the

How to pick colums from a ragged array?
I have a large dataset (~1 million rows) of three variables: ID (patient's name), DATE (of appointment) and DIAGNOSIS (given on that date). Patients may have been assigned more than one diagnosis at any one appointment - leading to two rows, same ID and DATE but different DIAGNOSIS. The diagnoses may change between appointments. I want to subset the data in two ways: - define groups

re: GUI's for teaching
Hi, Have you seen the tcltk package? I believe it is a better option than the one you outline in your message. Why develop a Windows-only GUI? Maybe in a few years your teaching department will give up Windows for Linux (for the reasons you wrote about R: it is free, advanced, and adaptable). There is an article in R News (vol.1, n?3) by Peter Dalgaard on the tcltk package, and the latter

'symbols' not plotting correct circle radii
Hi there. I have been plotting some circles using 'symbols', with radii representing my data, but the radii looked incorrect. It seems to happen with a single circle too: Symbols ( 0, 0, circles = 40, xlim = c(-40, 40), ylim= c(-40, 40)) If I put a ruler up to my monitor (technology!) to compare the radius with the axes, the circle isn't radius 40; it is closer to 15...
