For wishlist: sanity checks for subsets in lm, glm (PR#515)
I got stung by this yesterday: R> x <- seq(0,1,length=101) R> y <- x + rnorm(101)/5 R> test.data <- data.frame(x=x, y=y, cond=(x <= 0.5)) R> # A perfect fit! But very implausible parameter estimates. R> glm(y ~ x, data=test.data, subset=cond) Call: glm(formula = y ~ x, data = test.data, subset = cond) Coefficients: (Intercept) x -0.1283 29.5571

3d in R
Dear R-users and R-developpers, I've not been able to find 3d graphics in R, like Splus spin() or brush(). Are there any that I've missed and/or is anybody working on implementing these type of functions?

png output in batch
I'm trying to use R in a cgi script to produce graphics files in png format, and I'm having a problem. My shell command line looks like this: R </usr/dfs/auction/eligibility.R --no-save >/tmp/R.out and the line in the R script looks like this: png ("foo.png", pointsize=18) If I run outside the cgi context, it runs great. When run as in a cgi script, I get this error

building the development version
I'm trying to build the current development version of R on an SGI running IRIX6.5. Everything proceeds merrily until I reach the eda package. This is the error message I get if I cd to the appropriate directory and type 'make' or 'make all.' Does this make sense to anyone? -- Thanks, Debby gmake[3]: Entering directory `/l/fsc/dfs/src/R/src/library/eda' building

xgobi?
Hi all, As far as I understood from the documentation of xgobi. The package is intended to plot data in 3D (and more). Why if I enter example(xgobi) nothing displays even though the example calls also the xgobi command (yes I did load the library)? Do I need to install anything else for xgobi to work? I use R 1.6.1. on Windows 2000 platform or R 1.5.1 with RedHat 7.3 (none works). Miha

need help building R on SGI
I'm trying to build R-1.5.0 on an SGI. I downloaded the tar file just a couple of hours ago. These are the various variables I set before configuring, and the arguments to configure I'm using: export R_PAPERSIZE=letter CPPFLAGS=-I/usr/dfs/src/readline export LDFLAGS='-L/usr/common/lib -L/usr/lib32 -L/usr/dfs/src/readline' export CONFIG_SHELL=/v/bin/sh SHELL=/v/bin/sh ./configure

xgobi
Hi, Just started with exploring R. Nice ! (for many years using Splus). I tried to install and activate the package xgobi. - first download of xgobi.zip - then the R-command to install: install.packages('N:\\d024\\xgobi.zip',CRAN=NULL) - finally the command to attach the library: library(xgobi) Up to now, everything seemed to work. Also the help. No warnings that the

postscript: can't center plot
One of our color postscript printers needs a slightly larger margin than the default, so I'm trying to send slightly smaller graphics to it, but all the extra margin I provide ends up at the right and bottom of the page. These are the relevant (I imagine) ps.options: $paper [1] "special" $width [1] 10 $height [1] 8 $pagecentre [1] TRUE I tried this on two systems, in

trouble with maps
Has anyone else seen this behavior from the "maps" package? map('state', fill=TRUE) results in a lively mix of overlapping polygons inside a map of the US, but they have no obvious relationship to state boundaries. (See attached jpeg.) -------------- next part -------------- I reinstalled the maps and mapdata packages from ftp://ftp.mcs.vuw.ac.nz/pub/statistics/map/

lm() appears to fail with large number of variables (PR# 744)
This is not a bug, only evidence that the least squares fitting procedure is more numerically robust than I had expected. With 11 observations you can only estimate 11 linearly independent regression coefficients (at best). That's what you got (intercept + first 10 variables). How many did you expect to get estimates for? In summary: no bug, lm is working as advertised. > -----Original

In Win95/NT you can use xgobi (program and R interface) as well, provided you will install an x-server on your machine (a free one is available from http://www.microimages.com/freestuf/mix/).
