I have a plot of cumulative distribution function which is a step function,
I'd like to put a cycle at the right end of each line to indicate that the
value here is not available in this line.
How can I do that?
Thank you.
cdf<-function(x){
do.call("rbind",lapply(1:nrow(as.matrix(x)), function(i){
a<-x[i]
if (a<0.5){b=0.1}
else if (a<1){b=0.3}
else if (a<1.5){b=0.5}
else if (a<2.5){b=0.7}
else if (a<3){b=0.9}
else b<-1
}))}
xx<-seq(0,3.5,by=0.01)
pp<-cdf(xx)
plot(xx,pp)
