#Error in read.zoo("SC2.csv", sep = ",", format = "%m%m/%d%d/%y%y%y%y %h%h:%m%m") : index contains NAs Error message what am I doing wrong SC2.csv is a comma seperated file. The above data is right out out of the csv file, which is more like 30,000 rows. There are some NA for all of the variables except DateTime for a week here and a week there, but I can not find any missing dates. thanks stephen -- Let's not spend our time and resources thinking about things that are so little or so large that all they really do for us is puff us up and make us feel like gods. We are mammals, and have not exhausted the annoying little problems of being mammals. -K.
