[R] paste together a string object later to be utilized in a function

[moleps]

Sorry for bothering all of you. In the end it turned out to be much simpler than I thought. Takes a while to get used to the vectorizing idea. 



require(survival)
require(ggplot2)

ggkm<-function(time,event,stratum) {
	
	stratum<-as.factor(stratum)
	m2s<-Surv(time,as.numeric(event))
	
	fit <- survfit(m2s ~ stratum)
	
	w<-fit$time
	
	k<-fit$surv
	o<-length(levels(stratum))
	strata<-c(rep(names(fit$strata[1:o]),fit$strata[1:o]))

	upper<-fit$upper
	lower<-fit$lower
	f<-data.frame(w,k,strata,upper,lower)
	
	r<-ggplot (f,aes(x=w,y=k,fill=strata,group=strata))+geom_line(aes(color=strata))+geom_ribbon(aes(ymin=lower,ymax=upper),alpha=0.3)+xlim(0,fit$maxtime)+ylim(0,1)
	r<-r+scale_fill_brewer(f$strata,palette="Set1")+scale_color_brewer(f$strata,palette="Set1")
	return(r)
}





data(lung)
with(lung,ggkm(time,status,sex))

with(lung,ggkm(time,status,pat.karno))
