Hello, I am currently working with satellite tracking data for an organism with irregularly spaced location data in space and time (point data is occasionally spaced by 1-10 days). I have 4 columns of data, Lat, Long, Date, Time. I would like to linearly interpolate my data set so that I have one position per day with attached time stamps. I am fairly new to R, any pointers on code for this would be most helpful! Thanks! -- View this message in context: http://n4.nabble.com/interpolating-between-lat-long-position-data-with-time-tp1820014p1820014.html Sent from the R help mailing list archive at Nabble.com.

In addition, the R-sig-geo mailing list is a more suitable list to ask this question, you will probably get more response there. cheers, Paul -- Drs.
