density estimate
Hi,
I have a vector or random variables and I'm estimating the density using
"bkde" function in the KernSmooth package. The out put contains two vectors
(x and y), and the R documentation calls y as the density estimates, but my
y-values are not exact density etstimates (since these are numbers larger
than 1)! what is y here? Is it possible to get the true estimated density at
each

read.table : how to condition on error while opening file?
Hi,
I'm using read.table in a loop, to read in multiple files. The problem
is that when a file is missing there is an error message and the loop is
broken; what I'd like to do is to test for the error and simply do
"next" instead of breaking the loop. Anybody knows how to do that?
Example:
filelist <- c("file1.txt", "file2.txt",

odds ratio: how to create reference
HI there,
i know this is a basic question, though i need some help because this
is somewhat away from my current issue, but nevertheless interesting
to me... Lets assume i have some estimated probabilities, say
estimated by a logit model. i know i can also state them as an odds
ratio.
Now i?d like to state these odds ratios as a reference to a specific
outcome of my investigated

group by-like statement for 2-row matrix
Hi,
my problem is as follows:
I have a matrix of two rows like this:
2 2 3 4 4 4 5 5 6
1 1 2 1 3 3 2 1 1
Can I apply something like "group by" in sql? What I want to achieve
is the some of second row for each unique entry of first row:
2 -> 2 (=1+1)
3 -> 2
4 -> 7 (=1+3+3)
5 -> 3 (=2+1)
6 -> 1
Thanks!!

Disentagling formulas
I am writing a program in which I would like to take in a formula, change the response (Y) variable into something else, and then pass the formula, with the new Y variable to another function. That is, I am starting with
formula <- Y~X1+X2+X3
and I'd like to do something like
Y <- formula$Y
newY <- f(Y)
lm(newY~X1+X2+X3)
So far, it seems that my

error in predict glm (new levels cause problems)
Dear R-helpers,
I try to perform glm's with negative binomial distributed data.
So I use the MASS library and the commands:
model_1 = glm.nb(response ~ y1 + y2 + ...+ yi, data = data.frame)
and
predict(model_1, newdata = data.frame)
So far, I think everything should be ok.
But when I want to perform a glm with a subset of the data,
I run into an error message as soon as I want to predict

Sequences
Hi,
I am trying to make a sequence and am using a for loop for this. I want to
start off with an initial value ie S[0]=0 then use the loop to create other
values. This is what I have so far but I just keep getting error messages.
#To calculate the culmulative sums:
s<-rep(0,207) #as this is the length of the
vector I know I will have
s<-as.vector(s)

factors levels ?
Hi,
It's just some example code.. The application is uninteresting. I am
searching for some functionality.
X <- rnorm(100) //my data
Y <- seq(-3,3,by=0.1) // bin boundaries.
Now I would like to generate a - list of factors, length as X...
i.e.: all values in the range [-3,-2.9) have the same factor... [-3,-2.9) etc.
I would assume R has such a function but I cant recall which one

Help with vector gymnastics
Hello,
What is the best way of solving this problem?
answer <- ifelse(tf=TRUE, i * 5, previous answer)
where as an initial condition
tf[1] <- TRUE
For example if,
tf <- c(T,F,F,F,T,T,F)
over i = 1 to 7
then the output of the function will be
answer = 5 5 5 5 25 30 30
Thank you.
