PowerCut Killed R - is my code retrievable?
I've been tweaking code for several days on and off in R, cut and pasting in from a text editor (I just leave them open all the time). I think I got something that was usable but then a powersurge tripped the fuses and unfortunately the machine I was working on doesn't have a UPS.
Does R hold the command data in cache some place? I've purposefully not opened R since the crash so

Non-unique Values
I might be missing something really obvious, but is there an easy way to locate all non-unique values in a data frame?
Example
mydata <- numeric()
mydata$id <- 0:8
mydata$unique <- c(1:5, 1:4)
mydata$result <- c(1:3, 1:3, 1:3)
> mydata
$id
[1] 0 1 2 3 4 5 6 7 8
$unique
[1] 1 2 3 4 5 1 2 3 4
$result
[1] 1 2 3 1 2 3 1 2 3

Kaplan Meier - not for dates
I have some data which is censored and I want to determine the median. Its actually cost data for a cohort of patients, many of whom are still on treatment and so are censored.
I can do the same sort of analysis for a survival curve and get the median survival... ...but can I just use the survival curve functions to plot an X axis that is $ rather than date? If not is there some other way to

odfWeave - merged table cells, and adding information like totals and p-values
I'm hoping I'm missing some (probably fundamental basic process) which might make my life easier!
Lets assume I have a 3 column table summarizing results from a trial from three arms (Arm A, B and C).
For each arm there will be a number of pieces of information to report. The simplest example might be to compare this to the demographic comparisons often seen in clinical traisl where you

Comparing two different 'survival' events for the same subject using survdiff?
I have a dataset which for the sake of simplicity has two endpoints. We would like to test if two different end-points have the same eventual meaning. To try and take an example that people might understand better:
Lets assume we had a group of subjects who all received a treatment. The could stop treatment for any reason (side effects, treatment stops working etc). Getting that data is very

odfWeave - A loop of the "same" data
Before I go and do this another way - can I check if anyone has a way of looping through data in odfWeave (or possibly sweave) to do a repeating analysis on subsets of data?
For simplicity lets use mtcars dataset in R to explain. Dataset looks like this:

Using 'field names' of a data.frame in a function
I may be doing this wrong! but I have a function which I have simplified a lot below. I want to pass some 'field names' of a data-frame to the function for it to then do some manipulation of.

matchit - can I weight the parameters?
This may be a really obvious question but I just can't figure out how to do it.
I have a small dataset that I am trying to compare to some controls. It is essential that the controls are matched on Cancer Stage (a numerical factor between 1 and 4), and then ideally on Age (integer), Gender (factor), Performance Status(factor).
I'm using matchit to try and do this, but it seems to give

Summarising Data for Forrest Plots
I tried to post this a few times last week and it seems to have got stuck somehow so I'm trying from a different email in the hope that works. If somehow this has appeared on the list 20 tiems and I never saw any of them I apologize ;-)

Thanks Ivan and Calum
I continue to appreciate your support.
Calum, I entered the code snippet you provided, and it returns 'file

is happening is that the path from getwd() is being appended to the

Obtaining value of median survival for survfit function to use in calculation
Hi,
I'm sure this should be simple but I can't figure it out! I want to get the median survival calculated by the survfit function and use the value rather than just be able to print it. Something like this:
library(survival)
data(lung)
lung.byPS = survfit(Surv (time, status) ~ ph.ecog, data=lung)
# lung.byPS
Call: survfit(formula = Surv(time, status) ~ ph.ecog, data = lung)

?OT: Probabilistic Simulation
Sorry this may well be defined as Off Topic. I apologize in advance.
I am interested in performing what I think would be a probabilistic sensitivity simulation. I've done some crude ones before in excel but I'm wondering if R can help me do it more effectively?
I have a set of theoretical variables for simplicity lets use (what I think) is an easier example: I have a peg and a hole

Thanks for that. That seems to fix one problem (the lack of a

Is there a sexy way ...?
Admit it, Rolf. Haven't you wondered if S, in a more private way, is sexier than R?
OK, kidding aside, we have talked this to death.
Just FYI, the conversation was stimulating for some of us and I have continued on my own and located functions I see as useful in the stringi and stringr packages to make my silly version ever less silly! LOL!

If loop
"Or use <<- assignment I think. (I usually return, but return can only
return one object and I think you want two or more"
You can return any number of objects by putting them in a list and
returning the list.
Use of "<<-" is rarely a good idea in R.

If loop
OK. The fact it's in a function is making things clearer.
Are you trying to update the values of an object from within the function,
and have them available outside the function. I don't speak functional
programming articulately enough but basically
v <- 1
funA <- function() {
v <- v+1
}
funA()
cat (v)
# 1
You either return the v from the function so
funB <- function() {
