Plotting number of patients at risk below survival curve
Dear list,
does anyone know of a R-package that has implemented the increasingly popular
inclusion of the number of patients at risk below Kaplan-Meier curves like in
http://bloodjournal.hematologylibrary.org/content/vol116/issue19/images/large/zh89991058760001.jpeg
any hint (or negative answer) is much appreciated.
Thanks

survplot function
Dear R-helpers
I am wondering if there is an option to the survplot function in the design
package that allows for drawing Kaplan-Meier plots starting from 0 instead of
1, similar like fun = 'event' in the standard plotting function used on a
survfit object.
I apologize in advance for having missed any obvious informational sources but
I really didn't find anything in the

XML and odfWeave
Dear R-helpers,
this is just a notice to inform everyone that the current versions of XML and
odfWeave don't seem to be playing nice with each other.
Since it took me quite some time to figure that out, I thought that I let you
know. In my case it helped to install an older version of XML but your
mileage of course may vary.
Best regards
Thorsten

BA.plot with logarithmic axes (MethComp)
Dear R-helpers,
I am trying to plot a Bland-Altman-Plot using the BA.plot function from the
package MethComp. While there is a function to transform the values for
analysis as shown in the snippet below, I would like to have logarithmic axes
for display as well. The usual log = 'xy' does not work because of the
properties of the y-asxis (positive and negative values). I am sure that

Is there an R implementation for the "Barnard's exact test" (a substitute for fisher.test) ?
Hello R help members. I came across today with an article on Barnard's exact
test (http://www.cytel.com/Papers/twobinomials.pdf), that is supposed to
give a more powerful fisher.test - Because it doesn't assume that we know
the row and column totals are in advance. Any pointers to such a function ?
Thanks, Tal

sequential t-test - replies
[my original message to s-news & r-help is attached ]
No one possessed or knew of any S/R code for the sequential t-test. Also
it doesn't appear in the SAS index.
One or two suggested obtaining the S+ seqtrial software which may (or may
not) cover this, but this seemed to be a bit of a "hammer to crack a nut".
I have written a function based on the treatment in Wetheril

plot.new?
Hi all,
I am just beginning to use R and encountered a problem in trying to draw a
regression line using the command "abline(coef(var)" and similar ones but
got the error "plot.new has not been called yet". Does anybody know how can
I call plot.new? Is this an additional package to be found somewhere on the
web? Is it a functionality that I just have to "activate"

I am already using R under Window and would like now to try and install it

glm - predict logistic regression - entering the betas manually.
Dear All,
I know this may be a trivial question.
In the past I have used glm to make logistic regressions on data. The output creates an object with the results of the logistic regression. This object can then be used to make predictions.
Great.
I have a different problem. I need to make predictions from a logistic regression taken from a paper. Thus I need to (by hand) enter the reported odds

optimize simultaneously two binomials inequalities using nlm
Dear R users,
I?m trying to optimize simultaneously two binomials inequalities used to
acceptance sampling, which are nonlinear solution, so there is no simple
direct solution. Please, let me explain shortly the the problem and the
question as following.
The objective is to obtain the smallest value of 'n' (sample size)
satisfying both inequalities:
(1-alpha) <= pbinom(c, n, p1)

aggregate and median
Hello R-experts,
I have a simple question: how do I aggregate data using the median
function with na.rm = TRUE, i.e.
aggregate(x, list(x$y, x$z), FUN = '????')
I have tried 'median(x, na.rm = TRUE)' but that doesn't help.
Any suggestions are very much appreciated,

I have worked through the example provided by UCLA stats group:

However - what I would like to learn is how to use the constraint option.
So in the example given in the link i would like to introduce a constraint that
