Is there a way to make the plot(cox.zph(model)) use some other symbol than open circles? plot(cox.zph(model), pch=whatever) seems to have no effect. Thanks. --Chris Ryan

This TV series might have some advice on that. https://www.imdb.com/title/tt2543312/ --Chris Ryan On Tue, Jul 3, 2018 at 9:25 AM, J C Nash <profjcnash at gmail.com> wrote: > . . . Now, to add to the controversy...

I have both the 1st and the 2nd edition of Frank Harrell's book. I'll send you the 1st edition if you cover the postage. (4th class book rate would probably not be all that expensive.) Let me know...

I've set myself the task of learning about these packages, and about tidy data concepts. What is the relationship between plyr and dplyr? Does the latter replace the former (meaning I can concentrate on learning the latter)? Or is...

I may have to do a very simple demo about random variation in spatial epidemiology, without access to R. I would have internet access. Is anyone aware of a website where one can generate repeated examples of a simple CSR...

Unfortunately R-studio is not an option, but r-fiddle is perfect! Thanks. --Chris On Tue, Sep 5, 2017 at 1:58 PM, VIRGILIO GOMEZ RUBIO <Virgilio.Gomez at uclm.es > wrote: > Hi, > > You can use r-fiddle: > > http://www...

running R 2.5.1 on WinXP. plot(model formula here) produces 4 useful residual diagnostic plots. Two questions about them: 1. How can I isolate just one of the four, and have only that one be shown? str(plot...

This might be a bit off-topic, but up until recently (a day or so ago?) I loved using inside-r.org as a quick and easy way to access help pages on R commands. Took me to what I...

In the sparr package, risk() includes a logical argument for tolerance. If tolerance = TRUE, a pixel image of p-values is produced. Alternatively, the tolerance() function does something similar, but with more granular control of options. So basically one p...

Richard-- Nice. If I understand your code correctly, in the line ddm <- matrix("", (n+2) %/% nc, nc) I could instead use ddm <- matrix("", (n + nc - 1) %/% nc, nc) for generalizability, as I may have to increase nc as the list...

I think some inadvertent cutting and pasting may have made my last e-mail difficult to interpret. Here is the .tex file I get as output of Sweaving my .Rnw file. Note that "\Sexpr{2+6}" appears where you get...

You can see from the code below that the title of the dialog box is too long for the width of the selection box. How might I widen the box? Thanks. --Chris Ryan counties <- c("TIOGA", "BROOME", "ONTARIO", "ONONDAGA", "WESTCHESTER...

Is there a way to automate fitting and assessing loglinear models for several nominal variables . . . something akin to step or drop1 or add1 for linear or logistic regression? Thanks. --Chris -- Christopher W. Ryan, MD SUNY Upstate Medical University Clinical Campus...
