par(xaxp)
I think this is a bug; at least this behavior is not documented in plot
or plot.default.
plot.default resets xaxp, and leaves xaxp reset when it exits:
par(xaxp=c(0,1,4))
print(par("xaxp"))
plot(c(0,1),c(0.2,0.3))
print(par("xaxp"))

Are sockets supported on Irix?
When I try to open a server socket on the system setup listed below, I get
the following error:
> a <- make.socket(port=8091,server=TRUE)
Error in make.socket(port = 8091, server = TRUE) :
sockets are not available on this system
I just wanted to make sure that sockets were generally available for this
platform (or, perhaps, I need to upgrade to 1.2.2 on this system), before I

creating function bodies using body()
I'm having trouble figuring out how to create a function using "body<-"
(). The help file for body() says that the argument should be a list of
R expressions. However if I try that I get an error:

nlme: bug in getCovariateFormula (PR#1038)
I found that predict.gnls failed with a wierd error message about a
non-numeric argument to a binary vector in one of three nearly identical
uses.
Error in Inh/Ki : non-numeric argument to binary operator
(Inh and Ki are arguments to the function used in the formula for the
object whose predictions were requested).
It turns out that the problem is in getCovariateFormula().

typo and user-proofing in odesolve() (PR#1295)
A couple of minor points about the odesolve package
(which I am otherwise enjoying very much):
1. "scalar" is misspelled as "scaler" in the definitions of
the rtol and atol parameters
2. it is possible to crash R by doing something dumb, e.g
failing to read the documentation carefully enough and (a)
returning only a vector of derivatives and not a list of

lme() with known level-one variances
Greetings,
I have a meta-analysis problem in which I have fixed effects
regression coefficients (and estimated standard errors) from identical
models fit to different data sets. I would like to use these results
to create pooled estimated regression coefficients and estimated
standard errors for these pooled coefficients. In particular, I would
like to estimate the model

surprising behavior of match.arg() (PR#872)
If a function needs to be passed as an argument to another function,
default arguments to the function being passed are lost. Consider this
example:
fun1 <- function(x, A=c("power","constant")) {
arg <- match.arg(A)
cat(paste("A is:",paste(A,collapse=", "),"\narg is:",arg,"\n"))
cat("formals:\n")

Rcmd REMOVE does not allow --library argument (PR#957)
This is in Windows 98. The problem exists in both rw1021 and rw1023, using
ActiveState Perl builds 620 and 626:
C:\>Rcmd REMOVE --library=C:/R/Rlibs RBMDS
Unknown option: library
Usage: Rcmd REMOVE [options] pkgs
Remove the add-on packages specified by pkgs from the default library
tree (/library) or the tree specified via `--library'.

resolution of windows metafiles
I am having trouble getting smooth-appearing curves in figures produced as
windows metafiles using R (R-1.1.1 on Windows 98). When I import them into
a word processor (either MS Word 97, or WordPerfect 9.0), the figures
appear only slightly bumpy on screen, but when printed, there is a clear
jaggedness reminiscent of aliasing. Is there a fix for this (if the answer
is "upgrade to 1.2",

pdf page limit?
Is there a limit on the number of pages that can be in a pdf file? I am
using pdf() (on R version 1.4.1, running on Red Hat 7.1 on an Intel box)

Rai and Van Ryzin Model
R-users,
Has anyone implemented (coded) the Rai and Van Ryzin dose-response model from
their 1985 Biometrics paper. I'm trying to avoid re-inventing the wheel. If not
any hints on coding this would be greatly appreciated.
Thanks,

Parsing for list components
How do I parse an identifier of a list component, e.g.
mylist$mycomponent
or
mylist[[1]] ?
Parse does not do the job, e.g.
parse(text="mylist$mycomponent")
returns an expression with just one term, instead of "mylist", "$",
"mycomponent".
What I need is a way to extract the list name (e.g. "mylist"), given
an identifier of a component.

concatenating lists
Dear People,
I have been trying to perform concatenation operations on lists without
success. Consider the following example.
> x <- runif(2)
> y <- runif(2)
> z <- runif(2)
> xy <- list(x,y)
> xyz <- list(x,y,z)
I want to have a function foo such that foo(xy,z) is the same as xyz. This
appears not to be as easy as I thought, though there must be a way.
For example
