Dear R users,
If anyone can tell me how to extract the p values from the output of gee?
Many thanks in advance.

selections of data by one variable
Dear R experts,
My problem is as follows:
Suppose I have a data frame d comprising two variable a<-c(1:10) &
b<-c(11:20).
I now want to select a subgroup according the values of b.
I know if I just want to select, say, b=17, I can use f<-d[d$b==17] and R
will give me
> f
a b
7 7 17
However, if now I want to select a subgroup according to b==e<-c(13,15,17),
then the

negative variances
Dear R experts,
I had a question which may not be directly relevant to R but I will be
grateful if you can give me some advices.
I ran a two-level multilevel model for data with repeated measurements over
time, i.e. level-1 the repeated measures and level-2 subjects. I could not
get convergence using lme(), so I tried MLwiN, which eventually showed the
level-2 variances (random effects for

p value in MANOVA
Dear R users,
Can anyone tell me how to get the p value out of the output from
summary.manova?
I tried all the methods I can think of, but failed.
Many thanks

extracting standard error from lme output
Dear R experts,
I want to extract standard error from the output of lme, but I found
fix.effects() does not include SE of the coefficients. Many thanks in
advance.

error message in simulation
Dear R-users,
I am a dentist (so forgive me if my question looks stupid) and came across
a problem when I did simulations to compare a few single level and two
level regressions.
The simulations were interrupted and an error message came out like 'Error
in MEestimate(lmeSt, grps) : Singularity in backsolve at level 0, block 1'.
My collegue suggested that this might be due to my codes

Do you mean it does need a patch for isohybrid.c. And the patch looks like:
#if _FILE_OFFSET_BITS == 64
fseeko(...)
#else
fseek(...)

[LLVMdev] LLVM IR in DAG form
I don't want to get into the debate w.r.t. which IR style is better -
ask me over beer if you care about my opinions - but as an FYI, there
are serious proposals being worked on to introduce some notion of memory
def-use edges to help in analysing memory operations. I don't think
we've settled on a concrete proposal yet, but I wouldn't be surprised to

Re: Writting R Function
Hi,
I think I found the problem. It lies in my Fortran program. Is there a
way, after a DO loop, to make sure it does NOT return anything?
Cheers,

[LLVMdev] long double type on ARM
That is from 2.5, and just because there is nothing special listed in
config.gcc does not mean it doesn't work. For 2.5, the ARM port of
llvm-gcc did not require a separate llvm-arm.cpp source file, so
nothing needed to be added to config.gcc. It worked fine as far as I
know.
For 2.6, you will see that there are some ARM-related changes to
config.gcc in llvm-gcc.

[LLVMdev] LLVM IR in DAG form
Hi all,
this is Jeehoon Kang, a CS PhD student and a newbie to LLVM.
I am wondering why LLVM IR's basic block consists of a list of instructions,
rather than a DAG of instruction as in the low level (ISelectionDAG).
My gut feeling tells me that LLVM IR in DAG form may admit more
optimisations in a systematic manner. This is because data dependence is
more explicit in a DAG of instructions

Hi,
i want transform data and using apply(data,2,fuz)
, but i don't know why the values < low & > high don't get 0 or 1, they
get
the value from Formula ,too "((x-low)/(high-low))" what's not the
intention ?
....is switch more approriate !?
thanks for advance ,Christian

Mac Vorbis Player
I've got a working (standalone) Mac Vorbis player. It doesn't handle
clipping nicely (it makes narsty noises that XMMS doesn't), the code's
not commented yet, there's no other way to quit while the sound plays
besides force quitting, and there's no real error checking, but it works
and I got around the problem with os_types.h by putting a mac-specific

My problem, using Win2k,R.1.7.0, 256RAM is that i'm getting memory-erros go about the 1000.000 border , but
i need bigger test data. Ok is approriate buy more RAM, but is there a possibilty simulate a lot of single rows, one after
another and between this 2 steps -> Add th row to database and delete them

Loop Delaying
Hi there,
I know this question may sounds strange, but here it goes:
Is it possible to delay the speed of a for loop? For example, if I
have:
for (i in 1:100) {
blah blah blah
}
within the for loop I want to draw a series of plots, and combining the
plots together I'll have an animation. Problem is the loop is too fast
and I only see the end result (which is not surprising actually).
