handling of zero and negative indices in src/main/subscript.c:mat2indsub() (PR#7824)
This message contains a description of what looks like a bug, examples
of the suspect behavior, a proposed change to the C code to change this
behavior, example of behavior with the fix, and suggestions for 3 places
to update the documentation to reflect the proposed behavior. It is
submitted for consideration for inclusion in R. Comments are requested.
Currently, the code for subscripting

accepts mis-dimensioned index matrices I agree this is wrong and have made
it an error.

Fix for bug in match()
Hello all,
I posted the following bug last week:
# These calls work correctly:
match(c("A", "B", "C"), c("A","C"), incomparables=NA) # okay
match(c("A", "B", "C"), "A") # okay
match("A", c("A", "B"), incomparables=NA) # okay
# This one causes R to hang:

C dll compilation + S Poetry example
Dear all;
Working with the following code extracted from the document S Poetry
by Patrick Burns (from CRAN), I haven't been able to load the
resulting dll into R. The code is basically the calculation of the
quadratic form x'Qx:
static double quad_form(double *Q, double *x, long n)
{
long i, j, ij;
double ans = 0.0;
for(i=0; i < n; i++) {

Asterisk -> Nortel CS1K via NRS
Hi,
Was wondering if anyone had any tips or experience in getting a Nortel CS1K
and Asterisk 1.4.19 to talk to each other via NRS? So far I've gotten
asterisk to place calls to the CS1k via the NRS, however calls originated by
the CS1K get rejected by the NRS with a 404 Not Found message. If I take
the NRS out of the equation by replacing the IP address of the NRS in the
CS1K with that

using mle2 for multinomial model optimization
Hi there
I'm trying to find the mle fo a multinomial model ->*L(N,h,S?x)*. There
is only *N* I want to estimate, which is used in the number of successes
for the last cell probability. These successes are given by:
p^(N-x1-x2-...xi)
All the other parameters (i.e. h and S) I know from somewhere else.
Here is what I've tried to do so far for a imaginary data set:

about the subscript assignment porblem
Hi, Dear,
I have a problem for the new version 2.0 of R
When I put this code in it give me the error:
uis$ivhx3[uis$ivhx>0] <- 1*(uis$ivhx==3)
Error: NAs are not allowed in subscripted assignments
but this would happen in version 1.91
there are missing data in the data set and it is
represented as NA
the data set can be find on line

Yes, segmentation fault.

nested hierarchical design

I would like to know what syntax I need to use to do a nested anova for
1. a continuous variable and 2. count data (x out of y)

in R as well.
This is the hierarchical model I would like to use: a continuous

How to apply a function to subsets of a data frame *and* obtain a data frame again?
Dear all,
First, let's create some data to play around:
set.seed(1)
(df <- data.frame(Group=rep(c("Group1","Group2","Group3"), each=10),
Value=c(rexp(10, 1), rexp(10, 4), rexp(10, 10)))[sample(1:30,30),])
## Now we need the empirical distribution function:
edf <- function(x) ecdf(x)(x) # empirical distribution function evaluated at x

2 bugs in max.col() (PR#9542)
Dear R-Developers,
I think I found two bugs in max.col(). Ties between zeros are not broken, which might affect simulations. -Inf and Zero can be treated the same, which can give completely wrong results, e.g. when the second max is sought by replacing all maxs by -Inf.
To fix max.col I do offer the C-code behind my function rowMax(), which also handles NAs and seems to be faster. However,

reduce limit number of arguments in methods:::cbind
Dear all,
As far as I understand, the number of arguments in methods:::cbind is
limited by the "self recursive" construction of the function
which generates nested loops.
A workaround could be to use the internal cbind function on blocks of
non S4 objects. The limitation would then be reduced to the number of
consecutive S4 objects.

R-alpha: line types
Responding to my own post, after some hacking:
To fix the behavior of the following test code (the rect()s inherit the
lty set by the previous abline())--
x _ (1:100)/10
plot(x,sin(x))
abline(h=0,lty=2,col="red")
rect(1,0,2,0.5)
abline(v=2)
rect(3,0,4,0.5)
Here are some diffs (now all I have to do is wade through and get lwd
working properly ...)
