>From multiple data.frames I created two lists, one with temperature, one with gps data. With your help and lapply I managed to interpolate the timestamps of gps and temperature data. Now I want to merge/join both lists via the time-stamp, taking only times, where both lists have data. For the single data-frames that worked just fine with:
both <- merge(gps,temp) For the two lists of data.frames I first tried an lapply over both lists...something like both <- lapply(temp, gps, function(x){x <- merge.... Then I found "both<-merge.list(gps,temp)", but this doesn´t work either. It just transfers the first list "gps" to both Thanks for any hint, Thomas -- View this message in context: http://r.789695.n4.nabble.com/merging-lists-within-lists-via-time-stamp-tp3712631p3712631.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.
