Try this: # test data tt <- c("23:05:02", "23:10:02", "23:15:03", "23:20:03", "23:25:03", "23:30:03", "23:35:03", "23:40:03", "23:45:04", "23:50:04", "23:55:03", "23:55:03") x <- c(0.575764, 0.738379, 0.567414, 0.663436, 0.599834, 0.679571, 0.88141, 0.868848, 0.969271, 0.878968, 0.990972, 0.990972)
library(zoo) library(chron) z <- zoo(x, times(tt)) plot(z) Read the R Help Desk article in R News 4/1 about dates and times and also read the chron article in its references. Also read the zoo vignette which you can access like this: library(zoo) vignette("zoo") and also read ?axis in case you want to customize the axes.
