>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
