The zoo package can represent and plot irregular time series. There are three vignettes that describe it plus the help pages. See ?zoo ?plot.zoo ?xyplot.zoo e.g. library(zoo) z <- zoo(1:3, Sys.Date() + c(1, 2, 5)) plot(z) library(lattice) xyplot(z)

Hi, I am getting accumulated data from PostgreSQL, ie for every day in which a condition is true I get the number (count) of cases. Starting date is 2008-01-01 and end day the last day for which the condition is true (which is not necessarily today). I obviously do not get records (dates) with count = 0, in other words this is not a complete list of every day since 2008-01-01. Now I want I plot this, with the sum on the Y axis and the months on the X axis, preferably as a line drawing. Any ideas? el -- Dr. Eberhard W.
