Thanks. I have later realised that if data frames are unequal (i.e. data2edit 01:23:42 01:23:47 01:23:51 01:23:54 01:23:58 01:23:59 the result for 'y' is $y [1] NA NA NA NA NA NA Similar error occurs with the 'zoo' package. Is it better to do interpolation/further manipulation in another software tool? ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
