Hi Just in case somebody could be interested I've found that
unlist(lapply(split(mydata,as.Date), cummax)) could make the job but I don't know if it's the proper way if I want to use zoo objects. Any suggestion?? -- View this message in context: http://r.789695.n4.nabble.com/aggregate-with-cummax-tp2331991p2332653.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
