...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(&qu...

Buenas tardes, Quiero aplicar la función rbind y necesito tener los mismos nombres de columnas. Como tengo unas 195 variables en cada dataframe, necesito hacerlo de una forma rápida. Tengo 9 bases de datos y tengo que fusionar todas. ¿Como puedo comprobar que los nombres de las variables son los mismos? Y de lo contrario, ¿como detecto las diferencias? He probado con

Hi, I have the following data management issue. I am trying to combine multiple years of ethnicity data into one variable called ethnic. The data looks similar to the following id ethnic07 ethnic08 ethnic09 ethnic10 1 1 1 1 1 2 1 1 2 2 3 3 4 4...

...ed to the standardized incidence ratio concept found in epidemiology. To answer your technical question: fit <- coxph(Surv(......... mysurv <- survfit(fit, newdata= mydata) This will give a set of predicted curves, one for each observation in mydata. If we assume 2 treatments and 4 ethnicities, this means that there are 8 possible predicted curves. You can certainly take the curves for "trt=1, white" and "trt=2, white", plot them together on one graph, and call this your "adjusted" survival curves; the mydata data set would have two observations. T...

...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?

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...

Hi R-ers: I'm drawing a plot and have used different line types (lty) for different race/ethnicity groups. I want a legend that explains what line types correspond to the different race/ethnicity groups. I used the following code: legend( 1992 , 42 , c("Hispanic" , "non-Hispanic white (NHW)" , "non-Hispanic black" , "AI/AN" , "Asian" ) , lt...

WinXP, R-2.9.1 LS., I have been trying to solve a (for me) tricky issue. No matter what I've tried, I just can't find a way to do this. This is the issue: I have a text file (ansi text) "titles.txt" with lines of text; here is an example of such a file: >>>>> a brief history of polio vaccines anti-vaccination movements and their interpretations early warning

...(as in, total exclusion from paid employment) I faced in the labor market. Often from people who had high incomes. People don't know what it's like to live in that sort of fear, to wonder if next year you'll be living on the street or as a prostitute, just for being born to the wrong ethnic group. There are 200 million "white" people in America and, what, twice that number in Europe? How many "white" ethnic groups are there? I mean, in some places Chinese, Korean and Japanese are now "white" ethnicities. What kind of idiot thinks hundreds of millions o...

I had occasion recently to read in a one-line *.csv file that looked like: "CandidateName","NSN","Ethnicity","dob","gender" "Smith, Mary Jane",111222333,"E","2/25/1989","F" That "F" (for female) in the last field got transformed to FALSE. Apparently read.csv (and hence read.table) are inferring that if the entries of a file a...
