The correct command for forest plot should be "plot" (instead of
"forest") if you are using metagen from meta package.

Hi all,
I have a question about survplot in Design package. There is an option to print
the number of subjects at risk at the start of each time interval.
But I do not know how the time interval is decided, i.e. I do not know the
correspoding time to the number at risk printed.
How can I get the
I should note that I realise this function is pretty trivial to write

and I have not seen it. I

Is there a function to determine whether a set of vectors is cleanly

Hi Blue Jay,
If your sequences are small (<10Kb) and you have a few samples (~100)
the seqinr package from CRAN itself is a very straightforward way of
handling DNA sequences, but if you plan to do more sophisticated things
that can drain your RAM and processor time, I would definitely recomm

Samuel,
Since the difference in AUCs has insufficient power and doesn't really
take into account the pairing of predictions, I recommend the Hmisc
package's rcorrp.cens function. Its method has good power and asks
the question "is one predictor more concordant than the other in the

Hi
Another possibility could be that .RData was saved when some packages were
used and are not installed in this R version (I often percieve it when I
migrate among different computers). If the complete error message suggests
it you can install that package and you may open your .RData again wi

I have a problem fitting the following Weibull Model to a set of data.
The model is this one: a-b*exp(-c*x^d)
If I fitted the model with CurveExpert I can find a very nice set of

nls.lm function in R I can't obtain th
