rect function
Dear all,
I have a question about how to load data or (entering data )to each cell of
a rectangle created by rect .
e.g.
I have a matrix
rbind(1:2,1:2)
I have created a 2x2 rectangle by using:
a<-0:1/10
b<-0:1/10
kk<-expand.grid(a,b)
plot.new()
rect(kk[, 1], kk[, 2], kk[, 1] + .1,kk[, 2] + .1)
so how do we put the value of rbind(1:2,1:2) into the relevant

image/area plot
Dear R users,
I am trying to produce an image plot, that represents the proportions of
a factor (z variable), so that the number of squares of each colour
represents each factor level, with the respective label inside (sorry
for the crap English).
# Something like this:
kk=data.frame(fact=letters[1:10], freq=c(5,1,10,2,10,7,5,10,30,20)) #
factor and respective frequecies

“For” calculation is so slow
Dear All,
The function I wrote can run well with the small data, but with the large
data, the function runs very very slowly. How can I correct it? Thank you
very much. My function as below:
a<-c(1:240)
b<-c(1:240)
l=function(a,b){
v=0
u=0
uv=0
v[1]=0
u[1]=0
uv[1]=0
for (i in 1:(length(s)-1)){
v[i]<-((gx[[i]][b,(gx[[i]][a,1]+1)])-(gx[[i]][a,gx[[i]][a,1]+1]))/(gx[[i]][a,gx[[i]][a,1]+1])

Subset function
Hi,
can anyone help me how to use 'subset' function on my data frame?
I have created data frame 'data' with a few variables and with row names.
Now I would like to subset rows with concrete row names.
Using data[] I know how to do it. But I dont know how to formulate the
subset condition:
subset(data, subset = ?, select = c(var1, var2))
Thank you very much,

I'm trying to convert an S-Plus program to R. Since I'm a SAS programmer I'm not facile is either S-Plus or R, so I need some help. All I did was convert the underscores in S-Plus to the assignment operator <-. Here are the first few lines of the S-Plus file:

Help with R Function writing for Matrix
Dear all,
I have a task to find the first all zero row of a matrix X ( nothing known
about X). I need to write a function which returns either the row index of
the first all-zero row, or NA if there are no all-zero rows. and I also need
to locate all rows which are non-zero (should be a vector of row indexes).
Can somebody give me some hints on this?
Thanks a lot.

dnbinom(,size<1,)=0 (PR#842)
This came up on r-help but indicates a bug.
dnbinom(x,n,p) calls dbinom_raw(n-1,...)
which returns 0 for n<1.

difference in using with() and the "data" argument in glm call
Dear all,
I am dealing with the following (apparently simple problem):
For some reasons I am interested in passing variables from a dataframe
to a specific environment, and in fitting a standard glm:
dati<-data.frame(y=rnorm(10),x1=runif(10),x2=runif(10))
KK<-new.env()
for(i in 1:ncol(dati)) assign(names(dati[i]),dati[[i]],envir=KK)

Consistant test for NAs in a factor when exclude = NULL?
Dear folks?
Is there a function to correctly find (and count) the NAs in a factor when
exclude=NULL, regardless of whether their origin is in the original data or
by subsequent assignment?
In example number 1 below, where NAs are assigned by is.na()<-, testing the
factor with is.na() finds the correct number of NAs. In example number 2,
where the NAs are from the data, neither is.na(), ==NA,

Memory leakage/violation?
Hi,
I've spotted a possible memory leakage/violation in the latest R v2.1.1
patched and R v2.2.0dev on Windows XP Pro SP2 Eng.
I first caught it deep down in a nested svd algorithm when subtracting a
double 'c' from a integer vector 'a' where both had finite values but
when assigning 'a <- a - c' would report NaNs whereas (a-c) alone would
not. Different runs

[LLVMdev] alias analysis results
Hi there,
I am trying to understand how AliasAnalysis works out in LLVM. I used
the following simple test-case (test4.c):
--
void test()
{
int *jj, *kk;
int aa = 100;
jj = &aa;
*jj = 300;
}
int main()
{
test();
return 0;
}

Then I did "llvm-gcc -emit-llvm -c -o test4.bc test4.c" to get bc. I
tried the following 2 ways to get what I expect to get as
