I am not sure whether this is 100 % related, but I also get some unexpected behaviour with NA and rollapply: In the following example I would expect in Line 3 to see a 1 instead of an NA (mean out of [1, NA, NA] What do you think ?
> mean(c(1,NA, NA), na.rm=TRUE) [1] 1 > A1a<-zoo(c(NA, NA, 1,2,3,4,5,6, NA, NA)) > A1b<-rollapply(A1a,4,mean, na.rm=TRUE, na.pad=FALSE, align="right") > View(cbind(A1a,A1b)) > cbind(A1a,A1b) A1a A1b 1 NA NA 2 NA NA 3 1 NA 4 2 1.5 5 3 2.0 6 4 2.5 7 5 3.5 8 6 4.5 9 NA 5.0 10 NA 5.5 ----- Christian Langkamp christian.langkamp-at-gmxpro.de -- View this message in context: http://r.789695.n4.nabble.com/Zoo-bug-tp2287282p3065458.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.
