I have the dates of occurence of a repetitive event. I would like to plot the density of these events, as well as their specific temporal location. This is as far as I have gotten:
# generate some sample data: dates in 2014 random.dates <- sample(1:31, 100, replace=TRUE) random.months <- sample(1:12, 100, replace=TRUE) dd <- as.Date(as.character((paste(random.dates, random.months, "2014", sep="-"))), format="%d-%m-%Y") dd <- dd[!is.na(dd)] # plot density with a "rug". density(as.numeric(dd)) plot(density(as.numeric(dd))) rug(as.numeric(dd)) # But horizontal axis label is not very informative # would prefer labeling the start of each month plot(density(as.numeric(dd)), axes=FALSE) library(zoo) new.axis <- as.yearmon(dd) # but then what? This is where I get stuck--adding back a sensible axis Grateful for any guidance. Thanks. --Chris -- Christopher W. Ryan, MD, MS cryanatbinghamtondotedu Early success is a terrible teacher. You’re essentially being rewarded for a lack of preparation, so when you find yourself in a situation where you must prepare, you can’t do it. You don’t know how. --Chris Hadfield, An Astronaut's Guide to Life on Earth --- ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
