help with rowsum/aggregate type functions
Hi--
This is a question with a trivial and obvious answer, I'm sure, but I can't seem to find it in the help files and books that I have handy. I have a dataframe consisting of two columns, "Gene_Name," a list of gene symbols, and "Number," a numeric measure of how frequently a tag representing that gene showed up in a SAGE library. Several of the genes are

Fixed! Thanks all:RE: scatterplot to boxplot translation?
Thanks to David and Jorge - both of your helpful suggestions got me to the desired endpoint. In case anyone else has this question: I boxplotted my y variable data, but did the "cut" operation on the x variable in order to conserve the order of the y data. I see another suggestion coming in from another user that basically says this.
So, my working line of code was:

Running MCMC in R
Dear all
I am now running a MCMC iteration in the R program. But it is always
stucked in some loop. This cause big problems for my research. So I want to
know whether we can skip the current dataset and move to next simulated
data when the iteration is stucked? Alternatively, can the MCMC chain skip
the current iteration when it is stucked and automatically to start another
chain with different

simulation
I'm using an R program (which I did not write) to simulate multilevel data
(subjects in locations) used in power calculations. It uses lmer to fit a
mixed logistic model to the simulated data based on inputs of means,
variances, slopes and proportions:
?
(fitmodel <- lmer(modelformula,data,family=binomial(link=logit),nAGQ=1))
where modelformula is set up in another part of the program.?

Stopping all code execution when ANY error occurs (OR error handling without try/tryCatch)
Hi all,
I often run a bunch of code with Run Selection, and, after it's done
running, I find there have been like 20 errors, all due to an error that
occurred early in my code, which caused problems from there on. (I must then
scroll up through lots of code to find it.)
What I would like is for R to stop executing when an error occurs.
I am aware of a few solutions:
1. Put all the code in a

nesting in CoxPH with survival package
Hello all,
I am trying to understand how to specify nested factors when using
coxph(), and if it is appropriate to nest these factors in my
situation.
In the simplest form, I am testing two different temperatures, with
each temperature being performed twice in different experimental
periods (e.g. Temp5 performed in Period A and C, Temp4 performed in
Period B and D)
I am trying to see if survival

lme vs. lmer results
Hello,
and sorry for asking a question without the data - hope it can still
be answered:
I've run two things on the same data:
# Using lme:
mix.lme <- lme(DV ~a+b+c+d+e+f+h+i, random = random = ~ e+f+h+i|
group, data = mydata)
# Using lmer
mix.lmer <- lmer(DV
~a+b+c+d+(1|group)+(e|group)+(f|group)+(h|group)+(i|group), data =
mydata)
lme provided an output (fixed effects and random

Keep sourcing when there is an error
Hello,
I want to know if there is any way to avoid source() stopping when there
is an error.
Here is the content of my Main.R script:
source("~/R/source/Constructor1.R") # Object1 should be constructed
ifelse(exists("Object1"), # It's an S4 object
print("Object1 exists"), # I can't avoid using 'validity'

process of stepwise selection
Dear list,
I wanna select the significant variables relative to bird distribution,
using stepwise method.
However, the result is always the best-fit model.
Please kindly suggest if it is possible to show the selection process.

Creating q and p functions from a self-defined distribution
Hello all,
I am fishing for some suggestions on efficient ways to make qdist and
pdist type functions from an arbitrary distribution whose probability
density function I've defined myself.
For example, let's say I have a distribution whose pdf is:
dRN <- function(x,d,v,s)
# d, v, and s are parameters
return(d/x^2/sv/sqrt(2*pi)*exp(-(d-v*x)^2/2/(sv^2*x^2)))
this is a legitimate

Floating simulation error
Hi all, I am running a simulation and a curious error keeps coming up
that stops the whole process. The error is a subscript out of bounds
error, and it seems to happen at different points (floating around)
throughout the looping simulation. Say, for example, it crashes on
sample 1 - iteration 200. I can force it to start again on iteration
202 with all of the same settings, and it is

variables in object names
Is there any way to put an argument into an object name. For example,
say I have 5 objects, model1, model2, model3, model4 and model5.
I would like to make a vector of the r.squares from each model by code
such as this:
rsq <- summary(model1)$r.squared
for(i in 2:5){
rsq <- c(rsq, summary(model%i%)$r.squared)
}
So I assign the first value to rsq then cycle through models 2 through

[LLVMdev] Reversing a function's CFG?
Hello,
I was wondering if there was a quick way to reverse a function's CFG and, in turn, all basic blocks within it. Assuming all variables are globals, is there a quick way to generate a function's reversal? I highly doubt such functionality exists but I figured it was worth asking. I'm trying to develop an "undo function" generator pass that would be able to restore

byte-range requests
Hello everyone,
I did some initial tests and it seems that mongrel does not support
byte-range requests. Is this correct?
The reason I ask is that the iPhone requires byte-range requests to
work in order to stream audio or video from a web server.
Thanks in advance,

calculate quantiles of a custom function
Hi,
I guess that my problem has an obvious answer, but I have not been able to
find it.
Suppose I create a custom function, consisting of two beta-distributions:
myfunction <- function(x) {
dbeta(x,2,6) + dbeta(x,6,2)
}
How can I calculate the quantiles of myfunction?
I have not seen any continous function treated in the docs, and applying the
"quantile function" gives me an
