...e survfit of my coxph, I think it displays a curve for every single individual factor in my coxph, whereas I would like it to only display the adjusted curves for when Treatment==1 and Treatment==0. How can I do this? A simplified example of my code with only one effect-modifier is: simple.cox.ethnicity <- coxph(Surv(whenfailed,failed) ~ factor(Treatment) + factor(ethnicity)) #I've my data are attached already survfit.simple.cox.ethnicity <- survfit(simple.cox.ethnicity,survmat) #survmat is a data.frame that contains Treatment and ethnicity plot(survfit.simple.cox.ethnicity, col=c("...

...work! select(object, method, selections, options, html_options) end Names of object and method are passed in. How do I get current value of object? object[method] does not work because it is just a string not a real object. Say if have a model called Person which has a field called "ethnicity". There is an instance @person, and I will call validation_select(''person'', ''ethnicity) in my view''. Is there any way, I can get the current value of @person.ethnicity in view helper?

...the beamer class for presentation in Latex. One thing I have not become very good at is properly sizing my visuals to look good in a presentation. For instance, I have the following code that creates a nice plot (sorry, cannot provide reproducible data). bwplot(testedgrade~person_measure|gender + ethnicity, pfile, layout=c(2,5), main = 'Distribution of Person Measure by Grade\n Conditional on Gender and Ethnicity (Math)', xlab = 'Grade') Now inside my latex document using the beamer class for presentation I have the following \begin{frame} \frametitle{Distribution of...

Hi R-ers: I'm drawing a plot and have used different line types (lty) for different race/ethnicity groups.

Hello all, Let's say I have a character string "Race-ethnicity-----coding information" I want to extract all text before the multiple dashes, including the word "ethnicity."

You know, to this day I have never been able to bring myself to inform employers that I'm gay. The humiliation is just too much. It used to be that people hid homosexuality so they wouldn't get fired. Why should I have to disclose personal information just to satisfy some dumb diversity bureaucrat? For most of my 20s I was told I was a worthless over-privileged white male who deserved
