Rich,
The cenboxplot function uses cenros to estimate the censored values. The
cenros function requires at least 2 uncensored observations to be able to
do the regression. The cenros function does issue a warning when there are
more than 80% censored data, but that is suppressed in cenboxplot.
Rich,
The documentation for cenboxplot states that the second argument must be
logical and not integer. the function cenboxplot substitutes synthetic
values for censored values using ros, hence the error message from the ros
method.
I also do not understand how you expect group = 'SO4' to wo
Chris,
I think that you really need to quantify what you mean by correlation.
Things to consider would depend on what the matrices represent--are they
the estimates of the same set of N geographic points, are they traces of
the same line, are they traces of the same polygon outline? If either

I just checked. I've got 0.2.5. I'll update tonight and see if that fixes

The answer to your last question is easy--you cannot add a new component
to an object of class "htest" and have it printed by print.htest. But that
does not mean that you cannot add a component to the output for your own
use.
You will need to decide what you want for output, both visual
Anybody use fgui? I find it very handy.
I have a question about an argument to the call to gui in the first

I'm curious. I've used the paired-prentice Wilcoxon test for the analysis
of parried survival data. I haven't run into use of the coxph for that
previously, but I have seen it referenced a couple of times in recent web
searches.

Dave,
I am a little confused. You ask about a triangle distribution, but
describe the situation as a relation between y and x. Do you really want a
piecewise linear fit of y to x? That could be gotten using nonlinear least
squares.

How about any:

The function which will tell you the index if any match

Andrija,
You should be able to extract the data that you want using a call like
this (AD substituted for your c)
with(AD, tapply(X2, X1, function(x) sort(x, dec=T)[1:5]))
That returns a list like this:
$`1`
[1] 10 9 8 7 6
$`2`
[1] 25 24 23 22 21
Just package it the way that you want.
