Thanks for the answer. I found that smth like below works subset <- c(1,0,0) series <- c(1,1,1,0,1,0,0,1,1,0,0,0,0,1)
subset1 <- paste(subset, collapse='') series1 <- paste(series, collapse='') xx <- gregexpr(subset1, series1, fixed=TRUE) as.numeric(xx[[1]]) ## yields the first element numbers in series [1] 5 9 -- View this message in context: http://r.789695.n4.nabble.com/detect-subset-in-series-tp4076285p4076644.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.
