Thanks for all the help on my earlier questions.....
How do you plot a simple time series with unequal intervals? I have the following
dateofpoll <- as.ts(c("6/1/02", "7/1/02", "10/1/02", "1/4/03", "1/25/03", "6/7/03", "7/16/03", "8/17/03", "9/4/03")) reelect <- c(51, 47, 49, 51, 49, 49, 46, 45, 40) new <- c(28, 32, 35, 36, 41, 38, 47, 48, 52)
what I'd like is to plot reelect and new (maybe with smoothing) on a time scale, with the x axis labeled for date.....
But I can't figure out how, despite looking at ?ts and various things there
Thanks in advance
You can do it by converting to POSIX format, but a more convinient way is provided by the new contributed package "its" (Irregular Spaced Time-Series, on CRAN) by Giles Heywood (I have not tested it, though),
