R-alpha: R-beta:matrix & vector multiplication.
Both of these used to work and seem useful and harmless:
R> matrix(1,ncol=1)%*%c(1,2)
Error in matrix(1, ncol = 1) %*% c(1, 2) : non-conformable arguments
R> matrix(1,ncol=1)*(1:2)
Error: dim<- length of dims do not match the length of object

R-alpha: ?bug in [.data.frame
If you subscript a data frame using the names of the columns and there is
more than one column with the same name only the first one is found.
eg
mm<-data.frame(1:10,log(1:10))
names(mm)<-c("(offset)","(offset)")
mm[,"(offset)"] # only returns first column
mm[,"(offset)"]<-rep(1,10) # only sets first column
This *is* compatible with S, but I

R-beta: problem with gee() with singletons
A bug (misfeature) has been found in the S gee library (and thus in the R
gee library). The problem, which is shared by nearly all gee
implementations, involves the calculation of working correlations when
some clusters have only one observation. For compatibility reasons nearly
everyone uses the computing formula from the first SAS macro by Karim,
rather than the formula from the original GEE

R-beta: calling R from FORTRAN
There was a question earlier today, on either r-help or r-devel, about
calling R code from FORTRAN (I deleted it accidentally, so I don't know
which list it belonged to).
Anyway, there is a workaround to call R functions from FORTRAN which is
used in the "integrate" library. It was invented for S by Mike Meyer. The
FORTRAN code needs to be written to call a fixed C function and

0-extent matrices?
Is there a good reason not to allow matrix extents to be zero? I have been
writing a function which fits glms under certain linear constraints. I
fit the model with a reduced set of variables and then transform back to
the original set. This involves operating on submatrices of the
covariance matrix and subsets of the coefficients. Sometimes these subsets
are empty. A zero-length subset of the

R-beta: purpose of n in identify() function?
I think I am misunderstanding something about the identify() function.
if we have an example such as this:

> y_1:10
> plot(x,y)
> identify(x,y, n=1)
[1] 2 3
>
I clicked on two points and identify() returned both of them (2 and 3).
The manual says n is the maximum number of points to be identified.
If I specify n=1, should identify() return a single value?

R-beta: lmsreg
Does R have a function like the S(plus) function, lmsreg, Least Median
of Squares Regression? I am using R-0.61.

R-beta: question on dyn.loaded code
Hi,
when designing libraries for R, is it possible to call C/Fortran
subroutines from other dynamically loaded code?
The following example crashes R:
********* fn1.c *****************
void twice(int *i)
{
*i = 2 * *i;
}
*********************************
********* fn2.c *****************
extern int twice(int *i);
void negtwice(int *i)
{
*i = -1 * twice(i);
}

R-alpha: lbeta, ctrl-C and crashes
1. lbeta and beta do not work properly: lbeta returns its first
argument and beta gives the lbeta result.
In names.c lines 245-6, the codes for these should be 2 and 3 instead
of 1 and 2
2. crtl-C does not work (except the first time) on Red Hat elf Linux
(which has many many other problems as well) nor on the previous
version of Linux for Amiga. It worked on Slackware aout Linux and now
works

R-beta: Inquiry
To Whom It May Concern,
I have been informed that there is a public domain software called
"R" which is available through ftp://stat.auckland.ac.nz. I've tried the
address but I can't find the software itself. Can you help me on this. Thanks.
