I have a time series from 1933-2005 of precipitation at Fayetteville NC. I get the following error messages when I plot the zoo series. Any help would be appreciated. If you need the data I can dput it or send the csv. I didn't include it here because I didn't want to clog up anybodies email account. I know that this is not reproducible, and I will send along the file if needed.

These are date and times in the format YYYYMMDDhhmmss. I would like to take this column and make a chron object form them. I have tried a couple of the split family of functions but they need character input here is the data: date.time <- c(19851001001500, 19851001003000, 19851001004500, 19851001010000, 19851001011500, 19851001013000, 19851001014500, 19851001020000, 19851001021500,

Does anyone know of a test for stationarity of a time series, or like all ordination techniques it is a qualitative assessment of a quantitative result.
