On receiving an advent calendar from one of our course directors, I suggested we could track each other’s chocolate consumption in a survival analysis and establish who was eating significantly more chocs. Strangely, everybody refused to take part, so I am n=1. Looking forward to being able to highlight some “shocks” on the graph. So far, so smug

If you really want to know:

library(jpeg) today<-12 chocs<-c(5,5,7,7,7,10,10,10,12) lc<-length(chocs) choc.days<-rep(NA,25) for (i in 1:25) { choc.days[i]<-sum(chocs==i) } choc.surv<-25-cumsum(choc.days) holly<-readJPEG("holly.jpg") chocplot<-function(){ plot(1:today,choc.surv[1:today],type="s",lty=1,col="chocolate4",lwd=10, ylim=c(0,25),xlim=c(0,25), xlab="Day in December",ylab="Surviving chocolates", main="Survival of chocolates in Robert's 2012 office advent calendar", bty="n") text(x=10,y=23,labels="Survival curve",col="chocolate4") text(x=6.7,y=17,labels="One a day...") text(x=18,y=20,labels="Restraint",col="red",font=3) text(x=22,y=23,labels="Scrooge",col="green",font=3) text(x=7,y=6,labels="Abandon",col="red",font=3) text(x=3,y=2,labels="Nausea",col="green",font=3) lines(x=c(1,25),y=c(25,1),lty=3) rasterImage(holly,22,0,25,3) } windows() chocplot() jpeg("Advent_calendar.jpg") chocplot() dev.off(dev.cur())
